v0.5.12 released, and lots of documentation fixes

Release notes

Today I got a fire lit under me and decided to do a bunch of bug fixing and general performance improvements.

Changes since v0.5.11:

• Fixed a micro-optimization which was causing some pretty bad cache problems (I really should write a blog entry about this but tl;dr micro-optimizations are usually bugs in disguise)
• Fixed an issue which was causing the page render cache to not actually activate most of the time (you know there’s going to be a ramble about this below…)
• Fixed a bunch of spurious log meessages about nested transactions
• Refactored the way that markup=False works, making it available from all Markdown/HTML contexts
• Changed no_smartquotes=True to smartquotes=False (no_smartquotes is retained for template compatibility) (although I missed this on entry.title; I’ve already committed a fix for the next version)
• Improve the way that the page render cache interacts with templates
• Fixed an issue where changing a template might cause issues to occur until the cache expires

Documentation improvements

• The Apache/nginx deployment guide is vastly improved:
  • Now it uses UNIX domain sockets instead of localhost ports, making service provisioning a bit easier
  • The systemd unit is now a user unit instead of a system unit, which improves security and also allows for gentler service restarts
• The git deployment guide has been updated per the above, and also some of the code snippets are cleaned up
• The information about HTML processing and image renditions has been consolidated and cleaned up
• Information about private posts and user configuration has also been cleaned up somewhat
• Also lots of updates to the beesbuzz.biz Publ templates
