6th June 2023 / v23.0

  • Change The WPO365 | M365 APPS extension now includes the Gutenberg Editor Block to embed a SharePoint Document Library in WordPress (was previously sold as a separate extension called WPO365 | DOCUMENTS). [M365 APPS, DOCUMENTS]
  • Improvement An administrator of a website that receives OpenID Connect based ID tokens from multiple sources, can now configure the plugin to ignore ID tokens not issued by a Microsoft Azure AD based Identity Provider. [LOGIN+, SYNC, INTRANET]
  • Improvement A new (translatable) error message – for the case where the ID token is intended for a different audience – has been added. [LOGIN]
  • Improvement The Documents (shortcode and Gutenberg based) app – to embed a SharePoint library in WordPress – can now be configured to show / hide an “Open in SharePoint” link in the app’s header. [M365 APPS, DOCUMENTS, INTRANET]
  • Improvement The WPO365 authentication cookie (set when you configure an “auth.-only” authentication scenario) can be prefixed to help work-around server-side caching services / plugins that support naming convention based cache busting. [LOGIN]
  • Improvement 3 new developer actions have been added. See the updated documentation for details. [LOGIN]
  • Improvement Exceptions logged by the Microsoft Graph Mailer are earmarked when logged in ApplicationInsights with a new custom property “wpoMail”. Administrators can now configure a query-based alert in ApplicationInsights and trigger a new alert specifcally for mail-related errors if “wpoMail” equals “error”. [LOGIN, MS GRAPH MAILER]
  • Fix If certain conditions were met, the plugin would delete Audience related metadata unwantedly. [ROLES + ACCESS, SYNC, INTRANET]
  • Fix A SAMLResponse sent to the website will only be processed if the administrator configured SAML 2.0 based SSO for WordPress. [LOGIN]
  • Fix Various modifications to Microsoft Graph Mailer configurator should make it easier and more intuitive to configure it. [LOGIN, MS GRAPH MAILER]
  • Fix The Documents (shortcode and Gutenberg based) app – to embed a SharePoint library in WordPress – will now correctly load items in a folder. [M365 APPS, DOCUMENTS, INTRANET]
  • Fix The Documents (shortcode and Gutenberg based) app – to embed a SharePoint library in WordPress – now accepts a pagesize parameter to improve the performance when loading large libraries. [M365 APPS, DOCUMENTS, INTRANET]
  • Fix The Documents (shortcode and Gutenberg based) app – to embed a SharePoint library in WordPress – now loads all possible “locales” so it can display date columns e.g. “Modified” correctly. [M365 APPS, DOCUMENTS, INTRANET]
  • Fix The Log Viewer – to view and optionally resend emails sent using the Microsoft Graph Mailer – now calculates the last inserted logged item ID using MAX() instead of looking up the AUTO INCREMENT value, which may not be up-to-date. [MAIL]
  • Fix In an attempt to prevent the error “cURL error 28: Operation timed out after 15001 milliseconds with 0 bytes received” when integrating with Microsoft Graph, the use of the Expect: header has been disabled by default. [LOGIN, MS GRAPH MAILER]
  • Fix If support for multi-tenancy has been enabled and a user with a personal Microsoft account (e.g. outlook.com) signs in successfully, the plugin will no longer attempt to connec to Microsoft Graph to retrieve additional user attributes. [LOGIN+, CUST. USER FIELDS, SYNC, INTRANET]
  • Fix The license checker (for premium extensions / bundles) has been updated to work-around an issue whereby the license would be invalidated if the website’s home URL would incidentally returned the site’s IP address instead of its host name. This might happen occasionally, if you defined the constant WP_HOME using the $_SERVER[‘HTTP_HOST’] variable in your wp-config.php file and the site was requested by its IP address instead. [LOGIN]
  • Version bump for all extensions and bundles

3rd April 2023 / v22.1

  • Fix The built-in Microsoft Graph Mailer for WordPress will now exclude any custom headers that do not start with x- or X-, to prevent Microsoft Graph from not sending the message and reporting the following error instead: “The internet message header name […] should start with ‘x-‘ or ‘X-‘.”. [LOGIN, MICROSOFT GRAPH MAILER]

3rd April 2023 / v22.0

  • Improvement Administrators can now define configuration overrides in the WP-Config.php file. Support for configuration overrides must be enabled separately by checking the correspondig option on the plugin’s Miscellaneous page. See online documentation. [LOGIN+, SYNC, INTRANET]
  • Improvement The plugin will no longer skip loading when detecting wp-cli but instead skip any attempt to authenticate the current request. Support for wp-cli must be enabled separately by checking the correspondig option on the plugin’s Miscellaneous page. See online documentation. [LOGIN+, SYNC, INTRANET]
  • Improvement Administrators can now define a list of usernames of administrators that are allowed to administer the WPO365 settings in the WP-Config.php file. See online documentation. [LOGIN]
  • Improvement The WPO365 | MICROSOFT GRAPH MAILER plugin can now also log remotely to ApplicationInsights, allowing administrators to configure Azure’s Monitoring / Alerts feature to send – for example – an SMS whenever an exception is logged. [MICROSOFT GRAPH MAILER]
  • Fix Updated the permissions requested / scope for Azure AD B2C / OpenID Connect based Single Sign-on, after a previous change added ‘https://graph.microsoft.com/User.Read’ to the scope / permissions being requested (v21.8), which in turn caused an “invalid_request AADB2C90146” response being returned when attempting to authenticate with Microsoft. [LOGIN]
  • Fix Updated the permissions requested / scope for Azure AD / OpenID Connect based Single Sign-on, after a previous change always added ‘https://graph.microsoft.com/User.Read’ to the scope / permissions being requested (v21.8). Now this permission will only be added, if the plugin detects a premium extension (because any premium extension needs this permission when it attempts to retrieve user data from Microsoft Graph) [LOGIN]
  • Fix The application ID / application ID URI for Azure AD based protection for the WordPress REST API must now also be added to the wp-config.php (but only if the administrator has enabled the option to use wp-config.php for Azure AD secrets). [LOGIN+, SYNC, INTRANET]
  • Fix The Microsoft Graph Mailer for WordPress no longer “unauthorizes” itself, after it fails to retrieve an access token. Instead, WPO365 Health Messages are created and administrators should regularly check for errors [LOGIN, MICROSOFT GRAPH MAILER]
  • Fix Refactored the flow when sending emails from a different account than the one submitting the request to send an email to Microsoft Graph (= the default “From” account) to improve consistency, even when the alternative sending-from account is a Shared Mailbox, a Distribution List or normal User Mailbox. [MICROSOFT GRAPH MAILER, MAIL, SYNC, INTRANET]
  • Fix User synchronization will now generate an error and stop when it fails to create a new WP Cron task for the next batch of users. [SYNC, INTRANET]

  • Fix Updated PowerBI SDK. [LOGIN, INTRANET, M365 APPS]

16th March 2023 / v21.8

  • Feature Administrators can now enable Mail Staging Mode. This is useful for debugging and staging environments. WordPress emails will be logged and saved in the database instead of being sent. [MAIL]
  • Improvement The WPO365 plugin will now handle forms (e.g. Contact Form 7) that propose to send emails from a different account than the default from mail account, after it handles any other option (e.g Shared Mailbox or Send as / Send on behalf of). The proposed alternative from therefore always prevails. It can also be any type of mailbox e.g. User Mailbox, Shared Mailbox or Distributionlist. But it’s up to the adminstrator to ensure that the default from mail account is a either a member (e.g. of the Shared Mailbox) or has sufficient permissions to send emails as / on behalf of an alternative account (e.g. the Distributionlist). [MAIL]
  • Fix The initial OpenID Connect authorization request will now always include https://graph.microsoft.com/User.Read. [LOGIN]
  • Fix A public property $ErrorInfo has been added to the PHPMailer object to support integration with Gravity Forms. [LOGIN, MICROSOFT GRAPH MAILER]

  • Fix The link to launch the Mail Log Viewer would return “false” for FireFox users. [MAIL]

2nd March 2023 / v21.6

  • Improvement The (premium extension for the) Microsoft Graph Mailer for WordPress now also supports sending mail as / on behalf of another user or Distribution List. [MAIL]
  • Improvement The user interface for the Mail Log Viewer has been significantly updated with improved scrolling and selection and overall a clearer arrangement of the available information. [MAIL]
  • Improvement The Microsoft Graph Mailer for WordPress will notify the administrator in the form of a WPO365 Health Message when another plugin with mail-sending capabilities is detected. [LOGIN, MICROSOFT GRAPH MAILER]
  • Fix An alternative system for WordPress Nonces has been introduced to work around the fact that some browsers refuse to send the WordPress auth cookie along with HTTP 302 redirect requests, causing default WordPress nonce verification to fail unexpectedly, in which case the plugin would then log the warning “Could not successfully validate oidc nonce with value xyz”. [LOGIN, MICROSOFT GRAPH MAILER]

26th January 2023 / v21.5

  • Fix The recently added ID token verification did not take the mail-authorization flow into account. [LOGIN]
  • Improvement Administrators can now re-configure the WPO365 | LOGIN plugin to skip the ID token verification altogether, on the plugin’s Miscellaneous configuration page (but this is not recommended for production environments). [LOGIN]

  • Improvement The WPO365 plugin will now – by default – first try to look up an existing WordPress user by its Azure AD Object ID. This value uniquely identifies a user in Azure AD and is automatically configured when WPO365 creates a new user (or updates an existing one). [ALL]
  • Improvement To support Azure AD B2C user synchronization, newly created user synchronization jobs will now – by default – skip the domain check (whereby the login domain of the username of users retrieved from Microsoft Graph is matched against a list of supported custom domains on the plugin’s User registration configuration page). Existing user synchronization jobs must be updated manually. [SYNC, INTRANET]
  • Improvement If user synchronization has been configured, the default WordPress User list will be enhanced automatically. A column is added to show the date and time a user was last updated. A second column will show a button that allows administrators to reactivate a user in case that user has been de-activated / soft-deleted by WPO365 User synchronization. [SYNC, INTRANET]

  • Fix Overriding the “From” address was sometimes ignored. [MAIL, SYNC, INTRANET]

See the online documentation for details. [ALL]

This constant must be defined immediately after the line /* That’s all, stop editing! Happy publishing. */ as an array as follows URLs may be replaced by administrators as they see fit:
define('WPO_CDN', array('react' => 'https://cdnjs.cloudflare.com/ajax/libs/react/16.14.0/umd/react.production.min.js', 'react_dom' => 'https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.14.0/umd/react-dom.production.min.js'));
