 Ikiwiki started out supporting only [[Subversion|svn]], but the interface
 ikiwiki uses to a revision control system is sufficiently simple and
 generic that it can be adapted to work with many systems by writing a
-[[plugin|plugins/write]]. [[Subversion|svn]] is still a recommended choice;
-[[git]] is another well-tested option. 
+[[plugin|plugins/write]]. These days, most people use [[git]].
 
-While all supported revision control systems work well enough for basic use,
-some advanced or special features are not supported in all of them.
-Lack of support in [[ikiwiki-makerepo]] or auto.setup can make it harder to
-set up a wiki using that revision control system. The `rcs_commit_staged`
-hook is needed to use [[plugins/attachments]] or [[plugins/comments]]. And so
-on. The table below summarises this for each revision control system and links
-to more information about each.

+Notes:
+
+* Lack of support in [[ikiwiki-makerepo]] or auto.setup can make it harder to
+  set up a wiki using that revision control system.
+* The `rcs_commit_staged` hook is needed to use [[attachments|plugins/attachment]]
+  or [[plugins/comments]].
+* `rcs_getctime` and `rcs_getmtime` may be implemented in a fast way (ie, one log
+  lookup for all files), or very slowly (one lookup per file).
+* Openid username support allows avoiding display of Google's ugly openids.

 There is a page with [[details]] about how the different systems work with
 ikiwiki, for the curious.
