I've updated the instance to revision 4bc132 which is release 0.8.1 of writefreely.

The upstream announcement has all the details.

Relevant user visible changes for Qua:

• [FIXED] The way #hashtags are linked has been improved. This may affect your posts. Previously there was a requirement that a hashtag was preceded by a space or at the beginning of a line; this requirement has been dropped. The previous requirement was in place to prevent code snippets from having linked parts (for example comments or CSS colors).
