Happy New Year!

As a special present, we have placed a new major release of the Free Pascal Compiler, version 2.4.0, on our ftp-servers.

Changes that may break backwards compatibility are documented at:
http://wiki.freepascal.org/User_Changes_2.4.0

Downloads are available at:

the main FTP server at

ftp://ftp.freepascal.org/pub/fpc/dist/2.4.0/

and

Free Pascal 2.4.0 contains many fixes and new features. While we did not
manage to incorporate all planned additions, we believe this release offers a
nice collection of new functionality and bug fixes.


Please also see http://wiki.freepascal.org/User_Changes_2.4.0 for a list
of changes which may affect the behaviour of previously working code, and
how to cope with these changes.

Some highlights are:

Platforms:

UnicodeString type, offers reference counted UnicodeString support on
the Windows, Linux, Mac OS X, FreeBSD and Beos/Haiku platforms.

Packages:
* Many improvements to the XML units
* Many improvements to the database units
* Updated the common Mac OS X Pascal interfaces to r241, including
