= Version 2.1.0 =

+
Lots of new features!
|
| 42 |
+
|
| 43 |
+
* Thanks to a lot of jQuery help from [Boris Schapira](http://borisschapira.com/), a failed image regeneration will no longer stop the whole process.
|
| 44 |
+
* The results of each image regeneration is now outputted. You can easily see which images were successfully regenerated and which failed. Was inspired by a concept by Boris.
|
| 45 |
+
* There is now a button on the regeneration page that will allow you to abort resizing images for any reason. Based on code by Boris.
|
| 46 |
+
* You can now regenerate single images from the Media page. The link to do so will show up in the actions list when you hover over the row.
|
| 47 |
+
* You can now bulk regenerate multiple from the Media page. Check the boxes and then select "Regenerate Thumbnails" form the "Bulk Actions" dropdown. WordPress 3.1+ only.
|
| 48 |
+
* The total time that the regeneration process took is now displayed in the final status message.
|
| 49 |
+
* jQuery UI Progressbar version upgraded.
|
| 50 |
+
|
| 51 |
+
= Version 2.0.3 =
|
| 52 |
+
|
| 53 |
+
* Switch out deprecated function call.
|
| 54 |
+
|
| 55 |
+
= Version 2.0.2 =
|
| 56 |
+
|
| 57 |
+
* Directly query the database to only fetch what the plugin needs (the attachment ID). This will reduce the memory required as it's not storing the whole row for each attachment.
|
| 58 |
+
|
| 59 |
+
= Version 2.0.1 =
|
| 60 |
+
|
| 61 |
