You can download the most current version directly from GitHub. It's newer than the app stores. There's now a bunch of buttons including replying and up/down voting.
Maybe a dumb question, but how do I download the patched version (0.0.34)? The suggested download methods (play store, f-droid) all link to the 0.33 version still.
Edit - nvm I found the APK link. For other dumdums like me - go to releases and scroll to bottom of 0.0.34 release for the APK download.
Looks like they the new version linked below (I will as soon as I finish this reply). If for some reason it doesn't work, you have to long press the comment (usually in the white space) to make the message tools appear. There was an update about a week ago that broke something and hid them by default but they're there!
