+Bumping up of CODE_VERSION requires precise timing as described in the
+Developer's Guide. Otherwise working copies updated from SVN (for example,
+committers' copies) can run into issues:
+1. The source is rendered unfunctional after "svn update", asking users to
+ finish the "upgrade".
+2. Once the batch for the "upgrade" is executed, the queries, which get added
+ to the batch later, are likely to receive no real execution.
+3. In case the executed part of such partial batch is found incorrect later,
+ but before the release, fixing the wrong queries will be harder, hence they
+ have already been executed.
