Upgraded to Rails 2.0.2, except that we maintain
vendor/rails/actionpack/lib/action_controller/routing.rb
from Rail 1.2.6 (at least for now), so that Routes don't change. We still
get to enjoy Rails's many new features.
Also fixed a bug in Chunk-handling: disable WikiWord processing in tags (for real this time).
Files with "+"s in their names (e.g. from Wiki pages with spaces in their names) were not being expired properly. This is actually a Rails bug, but I fixed it by patching the action_cache plugin.
Added the action_cache plugin
http://agilewebdevelopment.com/plugins/action_cache
which does action-caching with ETags support. The built-in Rails ETags "solution" sucks, because it forces a page-rerender, even when the content is unchanged.
