v0.23.0

[hkalexling]

New Features

• Images are now cached with the HTTP ETag. This conserves bandwidth and improves page load time. (resolves [Feature Request] HTTP cache for thumbnails and pages #213, thanks to @Leeingnyo)
• Mango now preloads pages when in the paged mode. You can configure or disable the behavior from the reader modal. (resolves [Feature Request] Cache next page #196, thanks to @Leeingnyo)

Improvements

• You can now adjust the continuous mode page margin on the frontend with a slider. This deprecates the page_margin field in the config file. (resolves [Feature Request] Option to disable page spacing #211)
• You can now disable the page flipping animation in the paged reader. (partly [Feature Request] More features for paged reader #147, thanks to @Leeingnyo)

Bug-Fixes

• Fix a UI bug where the buttons are stacking in the reader modal when viewed on mobile.
• Fix paged mode image stretching issue. (fixes [Bug Report] Images are stretched at the paged mode reader #218, thanks to @Leeingnyo)
• Fix a bug where unnecessary pages are loaded in paged mode. (fixes [Bug Report] Unnecessary images are loaded when a paged mode #217, thanks to @Leeingnyo)

Misc.

• Remove MangaDex integration, as it's not working due to their changes of the API. We will be moving the functionalities to an official MangaDex plugin. See [Feature Request] MangaDex in API Improvements #170 (comment)
• Upgrade to Crystal 1.0.0 (thanks to @Leeingnyo)

Thank you for implementing the feature request.

I think the /upload/img/ path should also be cached for uploaded image.

@Elastic1 Currently uploaded images are only used as custom thumbnails, and all thumbnails are being cached at the API level.
