WordPress revisions do not normally include custom fields or taxonomies. This plugin extends revisions to include taxonomies and custom fields from PODS etc, allowing previous states to be captured, compared & restored as expected.
Usage 
There is no user interface, once installed and activated it will start 
capturing custom field and taxonomy information. The rest is stock WordPress revision functionality, except that this plugin formats the extra data into an easy to read format for display in the comparison screens.
The look for the compare screens can be changed in “settings.ini” (including turn off or changing the CSS used).
Features
<ul>
<li>
Taxonomies are saved as metadata with a key such as “$TAXONOMY:light_conditions” for the “light_conditions” custom category. The values are a list of “ID=Name” pairs. These would generally sort to the top (or close to it).
</li>
<li>
WordPress limits how the data is presented in the “Compare Revisions” screen, so the data is displayed as an alphabetically sorted list of fields and their values.
</li>
<li>
You can filter out metadata keys with one or more regular expressions if you don’t care about their values. Filtered out metadata is not saved, displayed or restored.
</li>
<li>
Some CSS is applied to the WordPress “Compare Revisions” screen which I believe makes it easier to understand, however you can disable this by renaming or deleting the CSS file (or adjusting “settings.ini”).
</li>
<li>
The unicode characters also make the output easier to read and you can change their values or remove them via “settings.ini”. For example, you can tell the difference between a repeating field and a single field with many lines.
</li>
<li>
Note that the “Restore This Revision” button restores what is on the right hand column and explains why it is greyed out for the last revision slot.

ImageMeta helps WordPress users manage image titles, captions, descriptions and alternate text more efficiently by providing one central paginated table of the uploads directory, editable fields that instantly update the chosen parameter, and a button to update information for all remaining parameters. Each image is grouped by WordPress-generated sizes with detailed information about how/if the image is attached or embedded. For orphaned images (not attached or embedded to any post or page), users may click a button to delete all iterations of this image to keep the uploads folder tidy and compact.
Simple, Straight-Forward Meta Updates
The uploads directory (and subdirectories) is presented in a paginated table, sortable by image title or upload date.
<ul>
<li>Update Title, Caption, Description or Alt values independently, or…</li>
<li>Update one, and copy across to the other fields.</li>
<li>Updates are performed on-the-fly and saved instantly, so no lengthy reloads are necessary.</li>
<li>A quick reference thumbnail is presented in-line to popup individual images for review.</li>
<li>An edit link is provided beside each image to fine-tune editing, using traditional WordPress administration or ERA404’s CropRefine WordPress Plugin.</li>
<li>Missing images are highlighted and an additional delete button is provided for safe/quick file grooming.</li>
<li>Quick-edit dropdowns are provided to open/edit posts where images are attached or embedded into the post content.</li>
<li>Delete button appears by orphaned or unused images not attached or embedded in any posts or pages.</li>
</ul>
ImageMeta now performs your routine house-keeping for you
<ul>
<li>
Images Not on Disk: Individual “Delete” buttons are shown by missing images (JPEG, GIF, PNG) that don’t have corresponding files in the uploads directory. Upon clicking “Delete,” the obsolete/old records will be removed from the WordPress database. Additionally, ImageMeta details a count of all missing images at the top of each page. For your convenience, you may click this link to delete all missing image records on the page, keeping your database compact and tidy.
</li>
<li>
Images Not Used in Posts or Pages: An additional delete link is shown to the right, beside the post counts, for images that are neither attached to a post/page (e.g.: featured image) nor embedded in any post/page content. Users who are vigilant about conserving disk use will appreciate this feature, for clearing out images (and their associated WordPress-generated sizes/iterations) from their uploads directory. This is especially helpful for images that are no longer being used or were previously uploaded but never posted.
