Commit 61de6b1d authored by louiz’'s avatar louiz’

Revert "Use a different Date data type"

This reverts commit 857c7d39.
parent a90f196a
Version 8.0
===========
- Changed the data type used to store the dates in the database. This
requires an automatic migration on the first start.
- Add a complete='true' in MAM’s iq result when appropriate
- The “virtual” channel with an empty name (for example
%irc.freenode.net@biboumi) has been entirely removed.
