+
+* bg/safer-local_to_univ (erts) (2010-02-11) 1 commit
+ - erl_time_sup.c: test for error return from mktime() (0f62f0b)
+
+We will not include this branch in R13B04 for two reasons:
+
+  o We are not 100% sure that this change is harmless on all
+    platforms in all timezones.
+  o We have an idea how the underlying problem can be fixed in
+    the calendar module (only) and I plan to try it out after the
+    release. We will keep this branch in pu as a reminder.
+
+Action expected from: Björn Gustavsson
+
+* db/tv_nthtail_fix (tv) (2009-12-01) 1 commit
+ - Fix for tv which restarts while trying to open a table (abe0759)
+
+Since our long-term goal is to migrate from gs towards wx,
+maintaining the old gs applications has a low priority for
+the Erlang/OTP team. Therefore, we will accept patches that
+seem sound, but we are unlikely to spend much of our own time
+fixing bugs.
+
+The author of this topic branch has found the real reason for
+the problem, but uncovered additional issues.
+
+Action expected from: The topic author - to decide whether to
+include the topic branch (which is a workaround, but does eliminate
+the crash) or to wait for a better fix from himself or someone else
+with an interest to advance the topic.
+
+* er/ei-decode_msg (erl_interface) (2010-03-11) 1 commit
+ - Add function to decode distribution header (864091a)
+
+Needs documentation and test cases.
+
+Action expected from: Topic author
+
+* jp/dependencies_makefile (compiler, erts) (2010-02-14) 3 commits
+ - squash! eliminate dialyzer warning (434e2ca)
+ - squash! fix snprintf for Windows (bf2708d)
+ - Add dependencies Makefile generation to erlc(1) and compile(3) (7cbc437)
+
+Approved in principle by the OTP Technical Board; now awaits a closer
+review of the implementation.
+
+Action expected from: Björn Gustavsson (the reviewer)
+
+* kr/gs-browser (gs) (2010-02-10) 1 commit
+ - Change lib/gs/src/tool_utils.erl to select multiple browsers other than Netscape (802d159)
+
+This topic branch introduces a new call to the deprecated regexp module.
+
+Action expected from: Topic author or anyone else with an interest to
+advance the topic
