2019-07-15 - version 2.0.19
* Fix: Check if return value of $order->get_date_created() is null before calling $order->get_date_created()->date() to avoid fatal error in some edge cases.
* New: Added clear_database_cache() to clear cache when order status changes.

2019-06-26 - version 2.0.18
* Fix: Some clients may query the API Status function before the API Key activation is completed, causing an inactivate API Key status to be cached and returned, so the errant cache is cleared upon API Key activation if it exists.

2019-05-09 - version 2.0.17
* Fix: insert_setting_after() method called only when is_admin() == true caused fatal error in some cases.
* Fix: " API tab can no longer be updated, as it was deprecated at version 2.0.
* Fix: Incorrect product_id was found if the client sent a legacy Software Title string, rather than the new numeric value for the product_id to the API Update function. This caused legacy API Update requests to fail, particularly for Variable products.
* New: Added Requires PHP version data option to the WordPress plugin information API.
* New: Requires PHP version field added on the Product edit API tab, and Variable product variation settings.
* New: Added icons to product API tab.

2019-02-28 - version 2.0.8

* Update: Change api-keys.php template column wording from Product by Product ID to Product Title.
* Update: Change api-keys.php template column Product ID cell data from URL to plain text to make it easier to copy.

2019-02-13 - version 2.0.7
* Tweak: Template overrides for yourtheme/woocommerce/api-keys.php, and yourtheme/woocommerce/api-downloads.php have moved to yourtheme/woocommerce/myaccount/api-keys.php, and yourtheme/woocommerce/myaccount/api-downloads.php
* Fix: The API Manager no longer relies on the woocommerce_downloadable_product_permissions table for download data, but rather only looks for the first Downloadable files URL on the product due to issues described in the following docs. Please read https://docs.woocommerce.com/document/digital-downloadable-product-handling/ for more information on how adding/changing Downloadable files URLs on products can cause download/update URLs to stop working since WooCommerce 3.0.
* Update: Added Product ID to api-keys-order-complete.php email template.

2019-01-29 - version 2.0.6

* Fix: WooCommerce Subscriptions subscription item checked for active subscription before creating API resource for item.

2019-01-12 - version 2.0.1
* Fix: Newly completed order active subscription check disabled as it returns inconsistent values with a WooCommerce Subscriptions subscription. Broke API resource creation with new subscription product order.
* Tweak: Use order creation time for API resource access_granted field.
* Tweak: Unlimited activations on product must have a limit value set, such as 1000, rather than 0 or empty.
* Tweak: If product activation limit is increased, all API resources with the product will have the activation limit increased to match. Decreasing the activation limit will have no effect on API resources.

2019-01-06 - version 2.0.0
* Dev: The next release may not run if PHP version 7 or above is not installed. Upgrade now if you haven't already.
* Dev: WooCommerce 3.0 or above is now required.
* Dev: WooCommerce 3.x Compatibility Release.
    - New: Added Order data store to conform to WooCommerce 3.x CRUD.
    - New: Added Product data store to conform to WooCommerce 3.x CRUD.
* Dev: If you are using WooCommerce Subscriptions with the API Manager, then WooCommerce Subscriptions version 2.1.2 or above is required.
* Dev: The entire plugin has been almost completely rewritten, and built on a new data model, but with full backward compatibility for client software. The changes are too numerous to list here. See docs to learn how everything works.
* New: If API Product is downloadable, then any URL can be used for the remote, or local server, file download.
* New: If API Product is downloadable the download file can be any file type rather than only a .zip file, and can be uploaded locally, using Amazon S3, or be accessible through a remote URL.
* New: API products are no longer required to be downloadable. The product could be a membership, a subscription, or whatever that requires an API Key for access. The API Key could be used as part of an account authentication process.
* New: API Products are no longer required to be virtual or downloadable. API Products can now be anything, even a service.
* New: Refactored and redesigned for version 2.0.
* Dev: Moved data to custom database tables.
    - Renamed woocommerce_api_manager_secure_hash to wc_am_secure_hash
    - Added: wc_am_api_resource
    - Added: wc_am_api_activation
    - Added: wc_am_associated_api_key
* New: Dramatically reduced API call response time.
* New: Reformatted API JSON output to adhere closer to JSON API format standards, http://jsonapi.org/, with backward compatibility. See docs for examples.
* New: Added optional pretty formatted API logging in three flavors: debug, error, and API responses only, plus a test log that can be used if manually debugging or testing code blocks.
* New: Support for .selectWoo().
* New: API Access Permission is controlled for the entire account by a Master API Key from the User profile screen.
* New: Introduced verbose and informative API debug and error logging, enabled under WooCommerce > Settings > API Manager > Debug.
* New: Unauthenticated API calls can be made to see if there are software updates available, but are not provided a download URL. Software that has an active API Key will see the update URL, but an inactive API Key will not. In both cases a WordPress plugin or theme will need to be in an activated state to send API queries. See docs for more detail.
* New: Software information and update API calls can use specific request to get serialized or JSON data returned.
* New: The constant WC_AM_TRUSTED_SOURCES can be added to the wp-config.php file to allow only specified servers to authenticate API Keys. WC_AM_TRUSTED_SOURCES has an array value of IP address used as a list of trusted sources, which the API uses to block unauthorized API access. Incoming requests will need to send an ip_address value to be compared against the trust source list. This feature could be used for a remote service that uses the API Manager to authenticate an manage API Keys.
* New: Items can be added/removed on an order in the backend dashboard, which requires an order status change. Adding a WooCommerce Subscription item to an order requires several steps, which will not work as expected when adding a subscription item to a backend existing order. Due to this limitation, WooCommerce Subscriptions must be created with a frontend purchase only.
* New: After a subscription switch both Master API Key, and Product Order API Key, remain unchanged. The number of current activations is reduced to become equal to or less than the total number of activations switched to.
* New: Product ID replaces deprecated Software Title in the product edit > API tab.
* New: Product Order API Keys can be custom generated at the moment a product is purchased using the 'api_manager_custom_product_order_api_key' filter.
* New: API Keys and API Downloads can now have their URL edited in Settings as they are now real endpoints.
* New: Amazon S3 access keys can now be defined in wp-config.php for better security, or saved in settings to the database for convenience but less security. The secret access key is encrypted if saved in the database.
* Tweak: Use new WC_AM_Scheduler() scheduler class to schedule batches that build, and rebuild, user API data for new installations only. This will help to manage load on the server, and elminiate exhausting server memory before the build has been completed on stores with a lot of orders.
* Tweak: Refresh order screen after adding, or deleting, API Key.
* Tweak: Refresh order screen after deleting, or toggle, API Key activation.
* Tweak: Cut load time of order screen Add API Key product list in half, and display only products that were purchased.

* Tweak: Moved templates/my-api-downloads.php to template/emails/api-downloads.php.
* Tweak: Moved templates/my-api-keys.php to template/emails/api-keys.php.
* Tweak: Added safeguard to prevent API products that have been purchased, are associated with an order, from being deleted.
* Tweak: Once the Product edit screen API checkbox is checked, the product becomes an API product, and the API checkbox cannot be unchecked, making this a permanent API product.
* Tweak: API requests directed to the old upgrade-api endpoint will be forwarded to the new wc-am-api endpoint. The API Manager PHP Library will be updated for this change, as should all non-PHP, and non-WordPress software.
* Tweak: API requests directed to the old am-software-api endpoint will be forwarded to the new wc-am-api endpoint. The API Manager PHP Library will be updated for this change, as should all non-PHP, and non-WordPress software.
* Removed: Add API Key product seletion removed from order screen.
* Removed: Per order activation toggle on order screen. API Access Permission can still be turned off for a specific product on the order screen..
* Removed: template/email-lost-api-keys.php.

* Removed: Support for .chosen().

* Tweak: Remaining support for WooCommerce Subscriptions < 2.0 removed.

2016-06-05 - version 1.4.4

* Fix: Fix above also fixed in templates/my-api-keys.php and templates/my-api-downloads.php.
* New: Added tabbed My Account pages for WC 2.6. Updated templates/my-api-keys.php and templates/my-api-downloads.php for WC 2.6.

* Fix: Check if the order exists, and if the order has been trashed, when handling API requests or displaying downloads and API Keys in My Account dashboard. Both my-api-downloads.php and my-api-keys.php will need to be updated if templates are overridden in a theme.

2016-01-12 - version 1.4.2
* Fix: Do not modify order completed email by adding a download or API Key section, if the order does not contain a downloadble product, or if the product is not set to use the API.

* Fix: Don't display API Keys or API Download on My Account dashboard for orders that have been trashed.

* Fix: Simple Subscription Product > API tab > Software Activation Limit would not update.

2015-11-08 - version 1.4.0
* Fix: If user_email was different than billing_email, the user_id could not be found, which caused activations and updates to fail.
* Fix: The get_download_count() method was used as a check to verify download permission. The method has been rewritten to provide a more reliable verification.

2015-11-03 - version 1.3.13
* Fix: Software and Update APIs now determine if an order uses the Subscriptions < 2.0 download permissions, Subscriptions >= 2.0 download permissions, or non-Subscription order download permissions. Hopefully this will catch all edge cases.

2015-10-30 - version 1.3.12
* Fix: Products purchased as a WooCommerce Subscription did not show correct My API Downloads download URL if the download file existed on the local server rather than on Amazon S3.

2015-10-28 - version 1.3.11
* Fix: If Download Expiry was not set on installations that do not use WooCommerce Subscriptions, downloads did not display. If my-api-downloads.php is used in the theme, be sure to update it.

2015-10-14 - version 1.3.10
* Fix: Downloadable product permissions were not correctly detected in Software and Update APIs if the product was not a subscription product.

2015-10-09 - version 1.3.9.9
* Fix: My Account templates, my-api-keys.php and my-api-downloads.php, updated to display subscription and non-subscription API Keys and API Downloads. Was only showing subscription API Keys and API Downloads.

* Fix: Fixed fatal error in admin/tools/class-wc-am-tools.php from missing closing parenthesis.

2015-07-24 - version 1.3.9.6
* New: Added First-Time Data Build button to settings page, to allow products to be setup and configured on new installs prior to build API data that includes API keys for customers who have already purchased products that are now setup to use the API Manager, so existing customers can start using their new API Keys.
* New: Added message with directions for new installations to do the First-Time Data Build and product configuration.
* Tweak: Use direct SQL query for some account first-time data prep to avoid overhead of some WordPress functions.
* Tweak: Overall better performance improvements for first-time API data build for new installs, and for emergency data rebuilds.
* Tweak: Improved intelligence of emergency data build, so it only replaces API Keys for customers that should have them.
* Tweak: Ensure first-time data is built only once manually from the API Manager settings screen, then hide the button. Also hide the button if API data has already been created for customers.
* Tweak: Only allow emergency, and first time build, buttons to be displayed on the settings page by defining the following constants in wp-config.php.
	- WAM_FIRST_TIME_BUILD_BUTTON
	- WAM_REBUILD_API_DATA_BUTTON && WAM_REBUILD_DOWNLOADBLE_PRODUCT_PERMISSIONS (must be defined at the same time)
	- For example: define( 'WAM_FIRST_TIME_BUILD_BUTTON', true );
* Tweak: Small performance improvements throughout the plugin.
* Tweak: On very old installations with WooCommerce Subscriptions activated, API Keys could have been added to subscription renewal orders, when they should only exist on the initial subscription order. Upon upgrade, a routine will remove those old API Keys from subscription renewal orders. The routine will only run once.
* Tweak: Fixed Lost API Key form not always sending out API Keys due to missed errors. Added more logic to catch errors, such as an email that does not have an account, so those errors will be displayed on the form.

2015-05-28 - version 1.3.9.5

2015-02-18 - version 1.3.9.1

2015-02-14 - version 1.3.9
* Tweak: WooCommerce 2.3 UI compatibility
* Tweak: Changed template override routine. To override templates in a theme place them as follows:
	- yourthemeroot/woocommerce/woocommerce-api-manager/my-api-keys.php
	- yourthemeroot/woocommerce/woocommerce-api-manager/my-api-downloads.php
* Tweak: Autoselect API License Key on Order edit screen on mouseover for easier copying.

2014-12-09 - version 1.3.8
* Tweak: Enforce API Access Permission order screen checkbox in the License and Update API.
* Tweak: When API Access Permission order screen checkbox is unchecked, deactivate all API Key Activations for that API Key on the order screen, and the My Account dashboard.
* Tweak: When API Access Permission order screen checkbox is unchecked, list the activation in My Account dashboard as deactivated and prevent deletion by customer.
* Tweak: If API Access Permission is unchecked, activation is inactive/disabled, downloads remaining is zero, or access expires has expired, the License and Update APIs will not be accesible by the API Key or activation attached to the order.
* Tweak: Added more License and Update API messages in response to queries.
* Tweak: APIs now only use unique instance as the means to identify an individual activation.
* New: Added Toggle button to activate/deactivate an activation individually on the order screen. This is enforced in the License and Update API.

2014-09-08 - version 1.3.7
* Example plugin and theme code moved to private Github repositories. Send WooThemes support your Github username, so the author can grant access to the repositories.
* New: WooCommerce 2.2 compatible
* New: WordPress 4.0 compatible
* Tweak: Sort My API Keys alphabetically in My Account. Located in templates/my-api-keys.php
* Tweak: Sort My API Downloads alphabetically, and without duplicates, in My Account. Located in templates/my-api-downloads.php
* Tweak: Do not display the Add API Key button on a subscription renewal order.
* Tweak: Do not create an API License Key for product orders unless the API and the Downloadable boxes are both checked on the Product edit screen.
* Tweak: Moved array methods to their own array class. Located in includes/class-wc-am-array.php
* Translation: Updated translation routine. Replaced base .po and .mo files with i18n/languages/woocommerce-api-manager-en_US.po and i18n/languages/woocommerce-api-manager-en_US.mo.
* Translation: Added Dutch translation thanks to David de Boer.
* Fix: WooThemes Helper License Key field did not display in some WordPress installations, so the plugin could not be activated.

2014-07-21 - version 1.3.6
* Tweak: Some web hosts have security policies that block the : (colon) and // (slashes) in http://, so only the host portion of the URL can be sent by the client software. For example the host portion might be www.example.com or example.com. http://www.example.com includes the scheme http, and the host www.example.com. Sending only the host also eliminates issues when a client site changes from http to https, but their activation still uses the original scheme. To send only the host, use a line like the one below:
	- str_ireplace( array( 'http://', 'https://' ), '', home_url() );
	- An example of the line above is in the root file of the API Manager example plugin and example theme.
	- Additional info: https://github.com/woothemes/woocommerce/issues/5616
	- When the : (colon) and // (slashes) in http:// request are blocked, the example plugin will return the following messages:
		- The license could not be deactivated. Use the License Deactivation tab to manually deactivate the license before activating a new license.
		- Connection failed to the License Key API server. Try again later.
* Tweak: The esc_url_no_scheme() and esc_url_raw_no_scheme() methods were added to sanitize URLs without prefixing http://, as esc_url() does.
* Tweak: Don't display Add API Key option on Subscription renewal orders. The active API License Key exists on the Initial Order for the subscription.
* Tweak: templates/my-api-manager.php has been removed, and split into two template files: templates/my-api-keys.php and templates/my-api-downloads.php.
* Tweak: Don't display disabled downloads in My Account API Downloads table.
* Fix: API License Key activation status checks would return inactive some of the time in error, if more than one product was purchased in the same order. This did not affect activations, deactivations, or updates.
* Fix: Invalid argument supplied for foreach() error appeared on order details and email order items templates due to false being returned to the associated filter rather than an empty array.
* Fix:  moved above the  foreach loop, so the table can be formatted with alternating table row colors, in the templates.

2014-06-30 - version 1.3.5
* Tweak: Implemented new singleton design pattern to ensure only a single instance of each class exists.
* Tweak: Wrote a more complete uninstall routine.
* Tweak: Uninstall hash table on plugin uninstall or deactivation.

* Removed: Removed all support for WooCommerce Software Add-On.
* Removed: Removed all support for WooCommerce 2.0.
* New: Download URLs for the My Account dashboard, and software updates, are now secured with hashed authentication. The new hash class uses password_hash() for PHP 5.5, a compatibility library for PHP 5.3.7 - 5.4.x to simulate password_hash(), and the WordPress class-phpass.php for PHP < 5.3.7. Download URLs can be set to expire from 5 - 60 minutes after the URL is generated for added security. The woocommerce_api_manager_secure_hash table was added to manage hashed authentication.
* New: Can now set the downloads remaining and access expires under Downloadable Product Permissions to restrict Update API downloads. Number of downloads limit, and time limit when access expires, can be set per product or per order.
* New: Can now set access expires under Downloadable Product Permissions to restrict License Key API activation. Time limit when access expires can be set per product or per order.
* New: New My API Downloads table added to the My Account dashboard with the following columns:
	- Product
	- Version
	- Version date
	- Documentation
		- Changelog
		- Documentation
	- Download
		- Download
		- Save to Dropbox
* New: New setting that allows all download links in email, My Account dashboard, and Order Details to be removed. Emails will provide a link to the My Account dashboard. All download links will still be available from the My API Downloads section of the My Account dashboard.
* New: New setting to enter the Dropbox App Key for the Save to Dropbox link.
* New: New Documentation setting in the product editor. When a documentation page is set, this provides the Documentation link in the My API Downloads section of the My Account dashboard.
* Tweak: Refactored API Manager Theme Example code to match approach used in the Plugin example. The theme name/software title is now parsed automatically from the stylesheet Theme Name:. The theme version is now parsed automatically from the stylesheet Version:. The plugin update class now uses the parsed version rather than the last checked transient version.
* Tweak: API Manager Theme Example now contains methods and a hook to remove product data and deactivate the license key when switched to a different theme.
* Tweak: The API Manager Example Plugin update class now uses the hardcoded software version rather than the last checked transient version.
* Tweak: The API Manager Example Plugin update API library can be found in api-manager-plugin-example/classes/class-wc-plugin-update.php.
* Tweak: Improved download handling class. Check if buffer is empty before emptying. Check if file exists, before attempting to open.
* Tweak: Improved JSON API responses.
* Tweak: Improved AJAX responses.
* Tweak: Moved Helper class instance from AMHelpers() to WCAM()->helpers().
* Tweak: Load shared classes as singular on-demand instances. This approach was also applied to the example plugin also, to prevent duplicate admin messages from the APIs.
* Tweak: The My API Keys section of the My Account page is now responsive.
* Tweak: Any amazonaws.com URL can now be used for Amazon S3 downloads, not just s3.amazonaws.com.
* Tweak: Software Activation Limit for a Simple Product type now returns an empty string rather than zero if no value entered.
* Tweak: API Manager Theme Example is now setup as a child theme for easier testing. Choose the parent theme available on your installation, or test with the code integrated into your parent theme.
* Tweak: woocommerce_get_template() changed to wc_get_template() for WC >= 2.1.
* Tweak: If order is made from United Kingdom, use licence rather than license.
* Tweak: APIs no longer check for wc_ prefix in the API License Key string now that support for WooCommerce Software Add-On has been dropped. This will prevent any issues if a prefix other than wc_ is used.
* Tweak: Removed unused global variables from local scopes.
* Tweak: Check if WP_HTTP_BLOCK_EXTERNAL is defined, and set to true, in the API Manager, example plugin, and example theme.
* Tweak: In the example update class, added a timeout of 45 seconds in the plugin_information() method for the wp_remote_get() function. This should provide more time for slow responding sites.
* Tweak: Local server WooCommerce download URLs can only be used once. If the URL is on a page, then the page needs to be refreshed to use the download URL again.
* Fix: The API Manager Theme Example had the product id and software title data values switched when sending to the Update API, allowing Dashboard > Updates to display, but Appearance > Updates did not display. Now both update screens display updates available.
* Fix: If a download URL was obtained, it could be used to download a product file with weak authentication an unlimited number of times. This is default WooCommerce behavior. This was fixed with the new hashing authentication class.

2014-04-08 - version 1.3.3
* Fix: $nonce_salt value was set improperly in the encryption class. The WooCommerce > Settings > API Manager > Amazon S3 > Secret Access Key will need to be saved again.
* Fix: Deactivation was returning an error, rather than an array. The new 'deactivated' key now returns the value true if the product was deactivated. The new 'activations_remaining' key now returns a string value containing the number of activations remaining, after the deactivation is completed. The 'reset' key has been removed, as it was never returned.
* Fix: Email and My Account > Order Details download links were not returning the Amazon S3 URL if that option was set.
* Tweak: The API Manager Example plugin wc_am_license_key_deactivation function code has been updated to demonstrate how to return a successful deactivation, and to display deactivation errors.
* Tweak: Prevent multiple activations from the same Domain/Platform for the same product. The domain/platform for each activation should be unique, and only one activation is now possible for each unique domain/platform for a product. Existing activations for a unique domain/platform will be removed for a product, so the new activation can be processed.
* Tweak: If Amazon S3 option is set, Email and My Account > Order Details download links are set to expire 24 hours after being generated.
* Tweak: Under WooCommerce > Settings > API Manager > Amazon S3, there is an option to turn off the download links in email and My Account > Order Details. If the Remove Download Link option is selected, a Download Files section is added to the customer completed order email, with a link to the My Account page to download files from that location.


2014-02-12 - version 1.3.2
* New: Amazon S3 support added. See http://docs.woothemes.com/document/woocommerce-api-manager/ for detailed instructions.
* New: Activation status check added to the License Key API. Takes the form of [status_check] => active or [status_check] => inactive. An example can be found in api-manager-plugin-example/am/classes/class-wc-key-api.php under the method name status().
* New: Added 'api_manager_extra_software_activation_data' filter hook to the License Key API to output current order data.
* New: Added 'api_manager_extra_software_status_data' filter hook to the License Key API to output currently active activation data.
* New: Added 'api_manager_my_account_delete' to the My Account template.
* Tweak: In api-manager-example.php of the Example Plugin, added several checks in the am_example_inactive_notice method.
* Tweak: In api-manager-example.php of the Example Plugin, the Api_Manager_Example_Key class is only instantiated once.
* Tweak: Removed urldecode from $_GET. The superglobals $_GET and $_REQUEST are already decoded. Using urldecode() on an element in $_GET or $_REQUEST could have unexpected and dangerous results. See Notes: http://us1.php.net/manual/en/function.urldecode.php.

2014-01-16 - version 1.3.1
* Tweak: Improved download handler
* Fix: Updated text domain
* Fix: On order complete emails, the API License Key and Software Title were blank if an API Manager 1.0 API License Key existed for an order.
* Fix: On lost API key emails, the API License Key and Software Title were blank if an API Manager 1.0 API License Key existed for an order.

2014-01-01 - version 1.3.0
* New: WooCommerce 2.1 compatible
* New: WordPress 3.8 compatible
* New: Added $extra information property to the Update API class. Can be used to send any additional information from the client software. The information can be any data type.
* New: Added api_manager_get_extra_api_data filter hook to access $extra information data sent from client software. This is a very powerful and flexible feature that has a lot of possibilities.
* New: Added new WooCommerce 2.1 hooks that allow the API Manager to cleanup customer data after an order is deleted.
* New: API License Keys can be found using Search Orders field. Limit of 100 License API Keys can be searched for per order.
* New: Can now add multiple products per order support. Multiple products, rather than only individual products, can be handled per order. This allows products to be purchased in multiples, bundles, chained, grouped, composite, etc, and to be assigned a unique API License Key for each item.
* New: Added searchable pull-down menu to add API License Keys to an order. Can now add a unique API License Key on the order screen for any existing line items in the order. Downloadable product permission must also exist for that order item. Only existing lines items for the order will be listed in the Add API License Key pull-down menu.
* New: Added delete API License Key button on order screen.
* New: Can now activate different products from the same domain name/platform on the same order, provided each product activation has its own unique instance id.
* New: Different products from the same domain name/platform on the same order can now check for software updates, provided each product has its own unique instance id.
* New: Added WooCommerce Settings API Manager tab with buttons to rebuild API Manager data, and to rebuild the woocommerce_downloadable_product_permissions database table.
* New: API Manager data will now be automatically built on a new install, so the Account Prep Tool plugin has been deprecated.
* New: Order Note is added for customer software activation/deactivation events. This option can be selected in the WooCommerce Settings API Manager tab.
* New: The software activation version on the order screen will be updated whenever the client software does an Update API query. The API Manager example plugin now has an updated License Key activation class, Api_Manager_Example_Key, that sends the software version along with the other activation data, so the Software activation will show the client software version immediately upon activation, and then it will be updated on each Update query.
* New: Third party plugins can now receive any type of data, and any data type, from client software through the Update API using the following hooks:
 	- Filter: api_manager_extra_update_data
 	- Action: api_manager_extra_data
* Tweak: Software Title in product API tab form must match the product_id the client software sends, or the client software will get an error message. This prevents a product from using the API Key of a different product to access the APIs.
* Tweak: Made the API Manager Example Plugin much easier to configure and integrate into products.
* Tweak: Classes can now only be instantiated once. Saves memory, and prevents the need to use globals.
* Tweak: Tightened security in the plugin code.
* Tweak: Added more activation error messages specific to new errors that apply to features added in this version.
* Tweak: Method added to output inline JavaScript.
* Tweak: Refactored downloads method into its own class.
* Tweak: Update API subscription detection for individual orders improved.
* Tweak: Updated _file_paths to _downloadable_files for WooCommerce 2.1.
* Tweak: Added detection for the new WooCommerce 2.1 wc_ prefix for the post meta _order_key key value.
 	- see https://github.com/woothemes/woocommerce/pull/4151
* Tweak: Refactored subscription status methods.
* Tweak: Refactored the helpers class.
* Tweak: Added downloadable product permission check to the License Key API.
* Tweak: Software Add-On support is now limited to only allow existing License Keys to access the Update API. The API Manager will no longer create a Software Add-On license key for new orders, and the Software Add-On activation table values will no longer be updated by the API Manager. Limited support for Software Add-On is provided so all existing customers can be migrated over to the API Manager License Keys.
* Tweak: Added check for empty product ID, instance ID, and API license key values in License Key API.
* Tweak: Added orderly sorting and display of API License Keys on the order and My Account screens.
* Tweak: Improved data presentation on the order and My API License Key Products screens.
* Tweak: Added Settings | Documentation | Support links to plugin administration screen.
* Fix: WooCommerce inactive warning resulted in fatal error due to $text-domain not being called correctly.
* Fix: API, Global, and Subscription checkboxes were not displayed properly in WooCommerce 2.1 or WordPress 3.8.
* Fix: Added CSS to fix some form elements not displaying properly under WooCommerce 2.1 in WordPress 3.8.
* Note: Although $text_domain is used in the update class, a string literal is preferred. For example 'wc_api_manager'. A variable cannot be read by some translation software.

2013-11-15 - version 1.2.1
* New: Added delete button on My Account dashboard to allow customer to delete domain names they activated for an order.
* Tweak: public $text_domain to the software update class, so it is now required. See the plugin example.
* Fix: class-wc-plugin-update.php in the example plugin, and class-cc-tk-plugin-update.php in the example theme, are now using $this->text_domain to do localization for error messages.
* Fix: CSS table column now properly expands on My Account page when the Subscriptions extension is activated.
* Fix: My Account page had some text that was not being run through WP translation functions.
* Fix: Admin Menu had some text not being run through WP translation functions.
* Fix: The API Manager will remove self-upgrade data for itself when it is deactivated for toddlahman.com customers. This change has no impact on WooThemes customers.
* Fix: Translation updates applied to plugin example, also applied to theme example.
* Localization: Refactored localization to use public $text_domain.
* Fix: Invalid request deactivation message was fixed in the example plugin in the class-wc-api-manager-menu.php file using the line:
	if ( $_REQUEST['option_page'] != 'am_deactivate_example_checkbox' ) {
* Fix: Invalid request deactivation message was fixed in the example theme in the class-cc-tk-license-menu.php file using the line:
 	if ( $_REQUEST['option_page'] != 'cc_tk_deactivate_checkbox' ) {
* Dev: Localization: French translation provided by Nicolas Maillard

2013-11-08 - version 1.2.0
* Tweak: In class-wc-api-manager-order-admin.php removed readonly attribute for Software Title and Software Version to allow those fields to be edited.
* Fix: Fixed option key typo in API Manager plugin example zip file.
* Tweak: Rewrote WooCommerce API Manager Account Prep Tool zip file to build API Manager data for old accounts, and to rebuild data for existing accounts. The rebuild feature allows improperly built data, due to product misconfiguration or bad data that already existed before the API Manager was installed, to be rebuilt by simply activating the plugin, then deactivate.

2013-09-28 - version 1.1.1
* New: First Release
