This is a bug fix release only. Plugin updating won't be necessary unless specific workarounds were used. A few of these bugs can impede proper functionality on non-singleton hooks and it is recommended that everyone upgrade.
If you haven't already seen it, I also had launched a coding wiki about a month ago:
http://wiki.tcwonline.org/ -- This wiki was launched to tie in various HL documentation our related projects have. We're also using it for coding articles and official project documentation.
Changelog:
Code:
- Fixed bug where returning newparams in a post hook would cause infinite recursion.
- Fixed bug where "meta load" could load the same plugin multiple times.
- Fixed bug where unloading a plugin could crash internal hook states.
- Fixed bug where unhooking a single hook would clear the hook chain.
