[Quickfix-users] Version 1.1.0 is available!

[<OM...@th...>]

This announcement was already made on quickfix-developers, this is a
forward for the quickfix-users and quickfix-announce lists.

Version 1.1.0, our first really major release since 1.0.0, is now available
from http://quickfix.thoughtworks.com.

Thank you to everyone who provided feedback, and submitted patches. This
version has major new functionality, bug fixes, more compliance fixes, and
performance enhancements. The release notes are posted below, but first a
couple words for people planning on upgrading.

First of all, this release is most important for people who plan on doing a
lot of throughput and maintain many sessions. The new filestore is much
more efficient memory wise, and the addition of the ThreadedSocketInitiator
and ThreadedSocketAcceptor provide much better performance and scalability.

When upgrading, please keep in mind the following:

- QuickFIX now uses libxml2.  The folks at libxml has requested all new
projects stop using libxml1 and we are complying with this. You will need
libxml2 installed to build newer versions.

- The signitures for toApp and toAdmin in the Application interface has
changed.  Your applications will need to reflect this change to compile.
The message class is no longer const, this allows you to add fields to a
message before it is sent out.  Ideal for adding additional fields to
messages like Logons and such.

- FileStore has been rewritten.  As a result, the file format has changed.
You should not mix QuickFIX logs from earlier versions with 1.1.0.

- PosDup message are now passed to the application callbacks.  You will now
need to have your application verify whether it wants to process a
particular message that may be a duplicate.

Other than that, here are the release notes.  Please provide everyone with
feedback about this version on this list.

RELEASE NOTES
________________

1.1.0
-----
Added support for messages with repeating groups.

Added ThreadedSocketInitiator and ThreadedSocketAcceptor. Each session has
it own thread
for listening on a socket and one for processing messages.

The signature for toApp and toAdmin have changed from ( const Message&,
const SessionID& )
to ( Message&, const SessionID& ). This allows applications to add fields
to messages before
they are sent out. Particularly useful for administrative messages that
need fields that arn't
added by default.

Filestore is much more memory efficient. Only file offsets are stored in
memory
and messages are retreived on in as needed basis. This keeps memory use way
down and also is a little faster for normal operations.

On Linux and Solaris upgraded from libxml to libxml2. It is recomended by
the libxml guys that all new applications use libxml2. configure will
verify
that libxml is installed on a system and automatically add the necessary
command line parameters.

Possible duplicate messages are now passed to the fromAdmin and fromApp
application
callbacks. Applications must now check for this field and determine how
possible
duplicate messages should be handled.

Values.h correctly generated enumerations for fields of type INT.

Validation works with STRING enumerations, not just CHAR and INT.

Sockets are now properly closed if a connection fails. This fixes a leak in
socket
resources that appeared after a large number of reconnect attempts.

RefTagID, RefMsgType are no longer added to reject message in versions of
FIX 4.1
and earlier. BusinessMessageReject no longer used in FIX versions 4.1 and
earlier.

Improved DataDictionary generation. More enumerations are listed.
