Matrix.org security breach

[Bartłomiej Piotrowski <bpiotrowski gnome org>]

The team behind Matrix.org announced[1] yesterday that an attacker
gained access to the production database, including users passwords used
for NickServ authentication with bridged network like Freenode or
irc.gnome.org.

While Matrix bridge is still down, we recommend users who were using
Matrix.org to access irc.gnome.org or Freenode to change their passwords
using following command in IRC client like Polari while logged in with
NickServ:

    /msg NickServ SET PASSWORD newpassword
