Subject [jira] Commented: (DERBY-1271) Release documentation for JDBC4 release
Date Wed, 13 Sep 2006 23:46:23 GMT
    [ http://issues.apache.org/jira/browse/DERBY-1271?page=comments#action_12434569 ] 
Laura Stewart commented on DERBY-1271:

Jean - 

Here is my attempt at wordsmithing...

"JDBC 4.0 functionality is not enabled in this Derby release. JDBC 4.0 is part of Java SE
6, which was not generally available for Derby 10.2. When you use Derby with a Java SE 6 virtual
machine, JDBC 3.0 is available. JDBC 4.0 is available only to developers who download Java
SE 6 and use it to add JDBC 4.0 support to Derby. The Release Notes explain how to build the
JDBC 4.0 functionality with Derby 10.2. When Java SE 6 becomes generally available, a follow-on
Derby release will include final JDBC 4.0 functionality. "


"Attention" is a good choice for this type of note.
I don't like the phrase "JDBC 3.0 is available."  It seems incomplete.  This is minor :-)
I think that the warning about compatibility with the final version of JDBC 4.0 should be
addressed in the Release Notes.

> We can't check in any of this work until we understand how our release trains line up.
However, the JDBC4-bearing release will need the following documentation:
> 1) Changes to the user guides. These need to be understood. We can analyze the scope
of these changes without checking anything in yet.
> 2) Summary page which explains what pieces of JDBC4 we tackled and what we passed over.
> 3) Verbiage for the Release Notes.
