[Help-smalltalk] GNU Smalltalk 3.0.2 and 3.0a released

[Paolo Bonzini]

GNU Smalltalk 3.0.2 and 3.0a will shortly be available from

   ftp://ftp.gnu.org/gnu/smalltalk/smalltalk-3.0.2.tar.gz
   ftp://alpha.gnu.org/gnu/smalltalk/smalltalk-3.0a.tar.gz


GNU Smalltalk 3.0a is the first release of GNU Smalltalk including 
support for Seaside. Therefore, the release cycle for this release will 
be shorter, and the first release candidate is out 2 months after the 
3.0 release.

Other changes include:

* ObjectMemory>>#snapshot and ObjectMemory>>#snapshot: return false in 
the instance of GNU Smalltalk that produced the snapshot, and true in 
the instance of GNU Smalltalk that was restored from the snapshot.

* The semantics of #on:do: were changed: executing off the end of an 
exception handler will always return from the associated #on:do:. Older 
versions of GNU Smalltalk either returned or resumed depending on the 
resumability of the exception.

* New tool gst-remote allows remote control of a GNU Smalltalk VM via a 
TCP socket.

* Packages can specify start/stop scripts. Start scripts can be 
activated with gst-load, while both start and stop scripts are supported 
by gst-remote.

* Unbuffered sockets available from class TCP.StreamSocket.

New goodies:

* DBI supports querying tables for schema information, and is integrated 
with the "ROE" (Relational Object Expression) package. ROE support is 
present for all back-ends (MySQL, PostgreSQL, SQLite)

* Seaside application server/web framework

* Swazoo web server
