regenerate-thumbnails

• Fix: Respect "Skip regenerating existing correctly sized thumbnails" setting.
• Fix: Don't delete all thumbnails when deleting old unregistered thumbnails size.

• Fix: Don't overwrite 'All X Attachment' button label with featured images count.

• Fix: Don't attempt to regenerate SVG's.
• Bump tested version.
• Update dependencies.

• Update plugin dependencies to the latest version.

• Bring back the ability to delete old, unregistered thumbnail sizes. Support for updating post contents is still disabled (too buggy).
• Various code improvements including string localization disambiguation.

• Fix slowdown in certain cases in the media library. #61
• Fix not being able to regenerate existing thumbnails for single images. Props @1do. #57 #60
• Fix JavaScript error that could occur if the REST API response was unexpected (empty or PHP error). #59
• Fix bug related to multibyte filenames. #62
• If an image is used as the featured image on multiple posts, only regenerate it once instead of once per post.

• Temporarily disable the update post functionality. I tested it a lot but it seems there's still some bugs.
• Temporarily disable the delete old thumbnails functionality. It seems to work fine but without the update post functionality, it's not as useful.
• Try to more gracefully handle cases where there's missing metadata for attachments.
• Wait until init to initialize the plugin so themes can filter the plugin's capability. plugins_loaded is too early.
• Fix a JavaScript error that would cause the whole regeneration process to stop if an individual image returned non-JSON, such as a 500 error code.
• Accept GET requests for the regenerate REST API endpoint instead of just POSTs. For some reasons some people's sites are using GET despite the code saying use POST.
• Make the attachment ID clickable in error messages.
• Fetch 25 attachments at a time instead of 5. I was using 5 for testing.
• PHP notice fixes.

Complete rewrite from scratch using Vue.js and the WordPress REST API.

• Fix PHP notice. (#20)

Maintenance release. A major rewrite is in the works on GitHub.

• Add "Regenerate Thumbnails" button to the Edit Media submit metabox. Props Brian Alexander for inspiration.
• Bump required WordPress version to v3.2 so that we don't need to bundle jQuery's progress bar plugin anymore.
• Context for translators.
