R14B will be released September 15.

We might include more topics that already are in 'pu'
into the release. New topics received from now on
are unlikely to be included in the release, unless
they fix fairly serious bugs.

* er/ei-decode_msg (erl_interface) (2010-03-11) 1 commit
 - Add function to decode distribution header (864091a)

Action expected from: Topic author

* jn/gen_stream (stdlib) (2010-07-15) 2 commits
 - Track gen_stream processes directly for accurate test results (38a4083)
 - Patch dev to reproduce jn/gen_stream (7694a74)

 . Add new gen_stream behaviour for efficiently consuming serial

This topic branch has a failing test case:

    We have now tested with and without this topic branch and when
    it is present that test case fails. We consider it proved
    to be guilty. The test case does not fail when run standalone
    so it seems to be tricky... Also, some of its own test cases
    fail sporadicly.

Action expected from: Topic author.

 - squash! eliminate dialyzer warning (434e2ca)

review of the implementation.

Action expected from: Björn Gustavsson (the reviewer)

Action expected from: Topic author or anyone else with an interest to
advance the topic
