+  ngIRCd 26~rc2
+  - ngircd.spec: Fix names of README.md and INSTALL.md, add ".md" extension.
+  - Update description texts in the README.md file, the RPM and Debian package
+    files and the manual page: bring them in line with the updated homepage.
+  - Server-Server protocol: Fix use-after-free when unregistering a directly
+    connected server sending a SQUIT for itself.
+  - Server-Server protocol: Detect bogus SERVER commands lacking a prefix.
+    Thanks Hilko Bengen (hillu) for finding & reporting this as well for the
+    patch & pull request (even if fixed differently).
+    Closes #275.
+  - Fix the PING-PONG logic: In ngIRCd 26~rc1 this was completely broken (while

+  - Test suite: Add missing files needed to test SSL support to "EXTRA_DIST",
+    so that they are included in distribution archives: in rc1, "make check"
+    fails when using sources from an archive and enabling SSL support.
+    Thanks to Hilko Bengen <bengen@hilluzination.de> for the patch!
