+GNU Parallel 20127022 ('Nai Soi') has been released. It is
 available for download at: http://ftp.gnu.org/gnu/parallel/
 
+This is a bugfix release with no new features. Probably a good release
+for stable long-term use.
+
 New in this release:
 
-* '-L n --pipe' will use records of n lines. This is useful when
+* GNU Parallel was presented at Chiang Mai Bar Camp
-  processing data that have fixed records with a fixed number of
-  lines (e.g. fastq).
-
-* --filter-hosts will remove down hosts. For each remote host: check
-  that login through ssh works. If not: do not use this host.
-  Currently you can not put --filter-hosts in a profile, $PARALLEL,
-  /etc/parallel/config or similar. This is because GNU Parallel uses
-  GNU Parallel to compute this, so you will get an infinite loop. This
-  will likely be fixed in a later release.
-
-* --pipe now uses fork() instead of busy wait. The performance should
-  be better on computers with >10 cores while remaining the same on
-  computers with few cores.
-
-* GNU Parallel will be represented at Chiang Mai Bar Camp
