ChangeLog for 0.8.15

Features:

Add active_window_ignore_refnum option With active_window_ignore_refnum ON, the current behavior for the active_window key (meta-a by default) is preserved: it switches to the window with the highest activity level that was last activated. With active_window_ignore_refnum OFF, the old behavior is used: it switches to the window with the highest activity level with the lowest refnum. (by Matt Sparks, bug #667)
Show new Charybdis +q list in channel windows (numerics 728 and 729).
Allow servers to belong to multiple networks.
Improve paste detection. Irssi now detects a paste if it reads at least three bytes in a single read; subsequent reads are associated to the same paste if they happen before 'paste_detect_time' time since the last read. If no read occurs after 'paste_detect_time' time the paste buffer is flushed; if there is at least one complete line its content is sent as a paste, otherwise it is processed normally.
Show "target changing too fast" messages in the channel/query window.
Use default trusted CAs if nothing is specified. This allows useful use of -ssl_verify without -ssl_cafile/-ssl_capath, using OpenSSL's default trusted CAs.
Show why an SSL certificate failed validation.
Make own nick and actions use default colour instead of white (by Tim Retout).

Change some characters illegal in Windows filenames to underscores in logs
Fix disconnects when sending large amounts of data over SSL
Show all nicks instead of just the first in an /accept * listing (Bug #704)
Make several signals without parameters available to perl again. In particular, this includes the "beep" signal (by Matt Sparks, bug #674)
Close the config file fd after saving (by Sven Wegener)
Check if an SSL certificate matches the hostname of the server we are connecting to.
Fix bash'isms, use command -v instead of which and use bc -l in /CALC.
Fix a crash with handling the DCC queue.
Fix crash when checking for fuzzy nick match when not on the channel. Reported by Aurelien Delaitre (SATE 2009).
