InspIRCd v2.0.13 has been released, downloads are here.
This version fixes a couple of problems on Windows, mostly related to IPv6 and GnuTLS. Stability problems in extra modules have also been fixed.
The USERIP command (provided by m_userip) has been changed to allow non-opers to query their own IP. Additionally, opers now require the users/auspex privilige to query the IP of other users (which is the same privilige that is needed to see real IPs in /WHOIS).
You can check out the issue tracker for the list of reported and fixed bugs (and enhancements) in this version.
