-Shimmie2 Release Candidate
+Shimmie2 -- 2.0.X Series
-~~~~~~~~~~~~~~~~~~~~~~~~~~
+~~~~~~~~~~~~~~~~~~~~~~~~
-Okay, so maybe my estimate of "it should be done within the week" was a bit
+Changes in 2.0.2:
-optimistic... I did get the first 3.5k lines of code done in a week, then
+ * $page->add_header() function pulled from development, as it's small, 
-another 1k of extensions in another week, but making it all work *properly*
+   and allows people to use development extensions (eg RSS)
-took 3 months...
+ * minor SQL tweak, huge speedup in several (but not all) cases
+ * ability to disable anonymous tag editing
+ * various internal fixes
+
+Changes in 2.0.1:
+ * Disabling anonymous comments doesn't break things
+ * When Shimmie is in downtime mode, there's a big notice in the sidebar
+ * A short opening tag (<?) was replaced with a long one (<?php), so people
+   with short tags disabled no longer see random PHP code
+ * Metadata searching was improved (see wiki -> user guide -> searching)
+ * Misc minor code cleanups
