Subject: Too many changes to even know what they were.
X-Git-Tag: 0.3.1-RC1~18
X-Git-Url: https://git.pterodactylus.net/?a=commitdiff_plain;h=e0e0192f88d5b5c27b7d29bcb3778d53e38a9897;p=Sone.git

Too many changes to even know what they were.

In short: the javascript was modified to handle elements more modularly so
that dynamically created posts and replies can be fitted with the same
functionality as pre-rendered ones. Also, posting with javascript is now
implemented.
