Hi all,

I'd like to remind everyone involved in development that requires db schema
migrations - please keep in mind the three related guidelines in our
official deployment policies -
http://www.mediawiki.org/wiki/Development_policy#Database_patches -
especially the third, which is to make schema changes optional.

Once a migration has been reviewed, please update
http://wikitech.wikimedia.org/view/Schema_changes with all pertinent
details, then get in touch for deployment scheduling.  There are good and
legitimate reasons to not follow the "make schema changes optional" policy
but if that's the case, please provide 3-7 days of lead time, depending on
the size of tables and number of effected wikis.

Best,
Asher
