2.1.1

• Fixed: Addressed an issue where the upgrader fired twice on new sites, causing the default settings not disable support for mime types with multiple file extensions.

2.1.0

• Upgrade: The stored settings will now convert from regex-based to key-based. This allows new types to be added and existing regexes to be adjusted much more reliably via the filter.
  • This changes the return value of function Pro_Mime_Types\get_allowed_mime_types_settings(). Since the value is useable in the same manner as before, we didn't change or deprecate the function name.
• Added: AVIF is now supported (image/avif, extensions avif or avifs). The site requires WP 6.5 or later to make the upload editable -- however, WP 6.5 has various bugs with this.
• Added: The settings link has been added to Pro Mime Types's listing on the plugin activation page.
  • Only the network administrator will see this in network mode, conveniently accessible from any subsite.
• Added: Pro Mime Types now registers the current "database version" in option pro_mime_types_db_version, separately for networks and single-site activations (depending on how it's activated). This option allows for upgrading the settings over time.
• Changed: constant Pro_Mime_Types\SUPPORTED_MIME_TYPES is now an associative array (with index keys) instead of a sequential one.
  • This change directly affects filter pmt_supported_mime_types, but sequential values can still be used, though they may not be stored properly.
• Fixed: .exe is now assigned the MIME type PHP recognizes instead of the one Windows does.
• Fixed: When setting the plugin to single-site mode from network mode, the plugin's network options are no longer cleared.

2.0.1

• Changed: .svg was inattentively marked as a "safe" file extension, which it's not. Consider using the Safe SVG plugin to sanitize SVG uploads (you must still allow them via Pro Mime Types). If you do not use SVGs, you should disallow them from being uploaded.
• Improved: The plugin is faster now since it memoizes repeated translations.
• Updated: New translations are available.

2.0.0

After eight years without updates (yet still working with the latest version of WordPress), Pro Mime Types got rewritten from the ground up. Now it's written by a senior PHP developer (me) instead of a noob (also me).

• Security: Resolved a security vulnerability (CSRF) due to missing nonces, where a rogue actor could enable and disable MIME-type support after tricking an admin into clicking a rogue link. Props Nguyen Xuan Chien via PatchStack.
• Added: You can now submit translations for this plugin via WordPress.org.
• Added: application/postscript, application/vnd.ms-cab-compressed, application/x-apple-diskimage, audio/aac, audio/ac3, audio/aiff, audio/flac, image/heic, and image/webp are now supported MIME types.
• Added: .2mg, .aac, .ac3, .aff, .ai, .aif, .aiff, .cab, .dmg, .flac, .heic, .img, .jfif, .jif, .md, .mp1, .mp2, .mpeg, .ogm, .smi, .vob, .xcf, and .xml are now supported extensions.
• Added: Extensive type detection for the image and video MIME types mentioned above. WordPress uses this for shortcodes and file extension conversion.
• Added: This plugin can now be used on a WordPress Multisite network in single-site mode.
  • However, network administrative capabilities are still required to change MIME-type support. Regular site administrators cannot enable MIME-type support on a network for your security.
• Added: You can now filter in custom MIME types via filter pmt_supported_mime_types. That filter must be registered before plugins_loaded.
• Added: The plugin options are saved when installing the plugin. This prevents extra database lookups on every request when the options are left as default.
• Added: Now allows uploading of file types even if WordPress fails to deduct them.
• Added: You can now sort through text, code, and miscellaneous file types in the Media Library.
• Changed: The "allowed MIME types" list now shows the actual values recognized by WordPress instead of inferring from the options set with this plugin.
• Changed: The plugin translation domain is now pro-mime-types, from promimetypes.
• Changed: Now requires WP 5.3 or later because it adds a test for the following PHP requirement.
• Changed: Now requires PHP 7.4 or later.
• Changed: The plugin and all its files now use license GPLv3, from "GPLv2 or later."
• Improved: All MIME type options are now stored in a single row, comma separated by "extension regex," instead of using 90 rows (one for each type).
  • After updating, all options will be migrated. It would be best if you did not downgrade, or you'll get 90 extraneous settings in your database.
  • Note: During the upgrade, if the plugin operates in single-site mode on a network, then only the first site that receives a request will get migrated the options; all other sites will use the default settings. This plugin has too small of a reach to consider this edge case. Moreover, the settings weren't always reachable in single-site mode, anyway.
• Improved: Overall performance by implementing better coding standards.
• Removed: Pro Sites support and all related settings; that plugin has been abandoned.
• Removed: Shortcode superadmin_showmimetypes.
• Removed: All old functions, filters, actions, callbacks, and globals.
• Removed: Support for .swf and .flv file extensions. Shockwave Flash is long gone.
• Removed: Support for .dv (DeltaVision) and .sea (Compact Pro) file sorting in WordPress's Media Library. I couldn't find a valid MIME type.
• Removed: Support for .php (PHP Hypertext Processor) file sorting in WordPress's Media Library. Consider using FTP.
  • Implementing this via Pro Mime Types would allow the uploading of PHP files, which we will refuse to implement.
