Hello derby-dev,
I would like your feedback on the release announcement which I will post
to various mailing lists. Step (21) of the release cookbook
(http://wiki.apache.org/db-derby/DerbySnapshotOrRelease) recommends:
"Every tech news blog remotely related to Java or databases will pick up
the announcement and post it verbatim, so it's a good idea to spell
check it, proofread it a couple of times, and/or get input from
derby-dev on its content." I plan to post to the following mailing
lists: derby-user, derby-dev, [email protected], and
[EMAIL PROTECTED] Please let me know what other mailing lists I
should notify. Please also let me know how I can improve the following
draft message.
Thanks,
-Rick
