Version 1.0.3 has been released, with the following new feature:

• Where supported, eliminates unintended image rotation on resize due to "orientation" EXIF data being lost.
  

Version 1.0.4 has been released, with the new feature and fix:

• Bugfix: The file size bug introduced in v1.0.3 has been fixed. This bug led to issues with the display of images via attachment.php (partial rendering; failed downloads). Corrective code has been added so that these issues are no longer experienced for already-uploaded images too.
  
• The support for auto-orientation has been improved so that it implements the full set of eight possible Exif orientation types.
  

Thanks to the report and testing of HLFadmin, version 1.0.5 has been released:

• Bugfix: when a file was missing in the filesystem, the corrective for the bug in v1.0.3 was causing errors to be generated. (An alternative to upgrading from v1.0.4 to v1.0.5 so as to fix this is to use the Find Orphaned Attachments functionality of the ACP to remove the database entries for any missing files).
  

Version 1.1.0 has been released, with these new fixes and features:

• Fixes some PHP 8 warnings.
  
• Adds (experimental) support for detecting animated GIFs/PNGs, and optionally resizing them or excluding them from resizing.
  
• Adds settings to stipulate usergroups and forums to be excluded from image auto-resizing.
  
• Adds support for watermarking images, including the ability to automatically back up original, pre-watermarked images.
  
• Adds some other miscellaneous improvements.
