There will most likely not be any more additions of features for the next release, just bug fixes for large bugs. I would like to give a huge shoutout to everyone that has been working on PRs for this upcoming release, it has been incredible. This includes but is not limited to @bactaholic, @micahmo, @Fmstrat, @CTalvio, @ajsosa, @guigs4, @coslu, @minicit! Please let me know if I have missed anyone :D

Another note: I have created a Matrix space for Thunder for anyone who wants to have general chat there or to get replies even faster. The link to it is here: https://matrix.to/#/#thunderapp:matrix.org

Be fully prepared to know that these pre-release versions may contain major bugs which could cause Thunder to crash or behave unexpectedly.

For things to test out, I would suggest:

• Test out everything you possibly can. Place heavy focus on general and most common actions (upvote, downvote, save, reply, comment, creating posts, etc)
• Look around for any issues with performance overall, or things that seem like they require an immediate fix

Without further ado, these are the changes from the last pre-release:

• Added initial way to block communities from the long press menu on posts. Long press a post in the feed page to show an option to block a community. Currently there is no way to unblock a blocked community, but that will come in a future release
• Added a whole bunch of UI tweaks and changes to post page, and in other places - contribution from @CTalvio
• Addition of community and user banners - contribution from @CTalvio
• Added pull to refresh to a few more pages - contribution from @bactaholic
• Showing collapsed comment count - contribution from @micahmo
• Sharing media directly as images - contribution from @michahmo

...and probably a whole bunch of other under-the-hood changes I forgot to note down 😅
