[Chameleon] Chameleon 2.4 beta1

[Julien-Samuel Lacroix]

Hi All,

This is to inform everyone that the Chameleon 2.4 release cycle has begun.
Chameleon 2.4 beta 1 is now available on Maptools website (or will be 
shortly).

http://chameleon.maptools.org/index.phtml?page=downloads.html

Or the MS4W package at:
http://www.maptools.org/ms4w/index.phtml?page=downloads.html

For developpers, there's now a new branch in CVS: branch-2-4
Please use this branch for any fix in 2.4 and keep in mind that only bug 
fixes
should go in that branch from now on. For new features, use the main CVS
version.

In the next few weeks we won't add new feature but take feedback on the new
release and make bug fixes. So please fell free to try it out and report 
any
problem you have with it.

This release include a bunch of bug fixes and enhancements. I'll try to
summarize them here.

Changes
-------

One of the big change of this version is in the language handling. The MLT
(Multi-Lingual Translator Module) now allow widget developpers to maintain
language files more easily via text files instead of DBF. Widget 
directories
now contains one file per language currently supported in Chameleon 
(english
or en-CA, french or fr-CA and dutch or nl-NL). The process to add a new 
one is
now simplier. Feel free to contribute new language! The migration of custom
widgets to the new language handling should be very straight-forward.

Another related change of this release is the addition of a new language:
dutch.

The other big addition is the support for popins in Chameleon. Popins are
just like popups, but open inside the main windows. This gives a bunch of
advantages like not being affected by popup blockers. Currently only the
MapNotes widget is configured to support this new feature. It is planned
to migrate all Chameleon widgets to the new popin archtecture as we get
feedback from the community. So let us know what you think of it.
