This release upgrades Instiki to Rails 2.3.4, which patches two security holes in Rails. See http://weblog.rubyonrails.org/2009/9/4/ruby-on-rails-2-3-4 There are also some new features, and the usual boatload of bugfixes. See the CHANGELOG for details.
Refactor the upgrade_instiki rake task. Based on the (very nice) JHerdman's http://github.com/jherdman/instiki/commit/64d305f2a85c1647bf4d2bb80069600df5d60432 but defaults to 'production' environment, instead. Instiki users don't know about production/development/test. Instiki defaults to 'production'. So should its associated rake tasks.
Web#files_path and Web#blatex_pngs_path now return Pathname objects. Based on JHerdman's http://github.com/jherdman/instiki/commit/5d1e8f420b4fcd6502c1cfa00d57002bea2868e0 but requires several other changes to the code (which assumed a string). Also, test for itex2MML 1.3.10 (you should update that too).
Andrew Stacey reminded me that this bug https://bugzilla.mozilla.org/show_bug.cgi?id=449396 is still unfixed. But it's easy to work around...

File retrieval (but not file uploads) should be allowed on a published web (this includes BlahTeX/PNG support). (Reported by Ari Stern).
