Version 3.21.4

• Fixed EPUB, MOBI and PDF files not working correctly on the Windows version of ACBR if the app is placed in a path containing spaces.
• Fixed images-only MOBIs not working.
• Fixed images-only EPUBs that don't store the image paths in img tags not working, and improved the code for the already working ones.

Version 3.21.3

• Added more ways to manage the "Convert Comics", "Extract Comics" and "Create Comic" tools' input list. The "Add Files", "Add Folders" and "Clear List" buttons are now at the top of the list and when the list grows bigger than 10 elements another set of the same buttons is placed at its bottom. Also, when right-clicking inside the list, the context menu now shows entries for those actions.
• Fixed setting the "Convert Comics" tool's "Input Folders Contain" advanced input option to "The image files from a single comic book each" no longer working.

Version 3.21.2

• Fixed the "Create Comic" tool duplicating pages in the output file when the input list consists only of images.

Version 3.21.1

• Made feed items with both description and content data in the RSS Reader start showing only the description and a expand/collapse button to show/hide the content, so it's easier to read and navigate them.
• Added Zona Negativa's feed to the RSS Reader's defaults.
• Fixed the changelog formatting in the check for updates modal when there is a new version.
• Fixed the Media Player's subtitle rendering so tags (italics, bold...) are shown correctly.

Version 3.21.0

• Added a new command line flag, --player, that makes ACBR launch in "Media Player Mode". In this mode the media player runs as if it was a stand alone application, without the Reader's main window or other tools.
• Added a new command line flag, --cli, that allows launching a text mode version of some of the tools ("Convert Comics", "Extract Comics" and "Create Comic") that runs directly through the command line rather than the graphical user interface.
• Fixed the RSS Reader showing the short summary instead of the full content for an RSS feed item if both are available.

Version 3.21.0-beta2

• Added a new command line flag, --cli, that allows launching a text mode version of some of the tools ("Convert Comics", "Extract Comics" and "Create Comic") that runs directly through the command line rather than the graphical user interface.

Version 3.21.0-beta1

• Added a new command line flag, --player, that makes ACBR launch in "Media Player Mode". In this mode it only shows the Media Player, as if it was a stand alone application, without the Reader or other tools.

Version 3.20.0

• Added new parameters to the custom filters in the Reader, invert and rotate hue, and a new default filter, Invert, to use as a quick Dark Mode (resetting the filters to the default ones is needed for the new one to be available if version 3.19.0 was previously used).
• Added the changelog from GitHub to the info shown in the Check for Updates modal.
• Added the current track's name to the Media Player's top bar when the advanced controls are enabled and the playlist is hidden.
• Fixed the Reader's new pages cache manager making the app crash on Windows when changing files in some circumstances.
• Fixed the Metadata Editor failing to update a ComicInfo.xml's pages list when requested and never ending the operation.
• Fixed the Metadata Editor failing to update some PDF's entries if the new value in the input field is empty.

Version 3.19.0

• Improved, significantly, the average page loading time in the Reader by implementing a pages cache that is filled in the background. The cache size can be increased in the Preferences (Comic Book Reader > Pages Cache), so it can fit more pages if the user doesn't mind the extra RAM usage.
• Added the option to create new page filters for the Reader (go to View > Filter > Manage Filters, or to the Comic Book Reader section in the Preferences), that can be customized by setting values for gamma, white level, black level, brightness, contrast, sepia and saturation.
• Added a new advanced image operation, black level / white level, to the convert, create and extract comic books tools.
• Added a button, shortcut and menu entry to take a screenshot of a video in the Media Player while it's playing.
• Added a new Preferences option to set the System Monitor size in the Appearance section.
• Rebuilt one of the libraries' Linux binary so it requires glibc 2.35 instead of 2.38 to run it, making the non-flatpak Linux versions of ACBR now, hopefully, compatible with older Linux distros like Ubuntu 22.04.
• Made some changes to the conversion tools to try to avoid potential EBUSY errors on Windows.
• Updated some of the core libraries to newer versions.
• Fixed not being able to open the metadata in the comicinfo.xml of a CBR file.

Version 3.19.0-beta3

• Rebuilt one of the libraries' Linux binary so it requires glibc 2.35 instead of 2.38 to run it, making the non-flatpak Linux versions of ACBR now, hopefully, compatible with older Linux distros like Ubuntu 22.04.
