= Release Notes for Clozure CL 1.4 =

== Supported Platforms ==
Clozure CL runs on the following platforms:
   * Mac OS X 10.4 and later (PowerPC and x86)
   * Linux (PowerPC and x86)
   * FreeBSD 6.x and later (x86)
   * Solaris (x86)
   * Microsoft Windows XP and later (x86)

The preferred way to get Clozure CL is via Subversion.  For example,
to get CCL for Mac OS X on x86, one would run the following command
from a shell prompt:

{{{
$ svn co http://svn.clozure.com/publicsvn/openmcl/release/1.4/darwinx86/ccl
}}}

Versions for other platforms are available by changing the `darwinx86` to
one of `linuxx86`, `freebsdx86`, `solarisx86`, `windows`, `darwinppc`, or
`linuxppc`.

Both 32 bit and 64 bit binaries are included with all versions.

  '''Important note''': to rebuild Clozure CL on Mac OS X 10.6 Snow Leopard, you must install the optional 10.4 support when installing Xcode.

== Reporting Bugs ==
Please use the Trac instance at  http://trac.clozure.com/ccl to review existing bug reports and to submit new ones.

== Known Problems ==
The 32-bit Windows lisp still doesn't run on 64-bit Windows.

== Notable Changes ==

The fasl file and image file versions have changed.

Code coverage http://trac.clozure.com/openmcl/wiki/CodeCoverage (r12300)

Export and document an interface to populations. (r12094)

Change in :sharing :private semantics (r12240).

Some user-contributed software may be found in `ccl:contrib;`.  Clozure doesn't maintain these contributions.

The #$ reader macro will now try to look up foreign variables if it can't find a constant definition.
This makes it OK to say, e.g.,  #$NSFontAttributeName (whereas before it was necessary to remember
that it was #&NSFontAttributeName).

PATHNAME-ENCODING-NAME (ticket:358)

It appears that Apple isn't going to provide a
way to set the gsbase MSR on x86-64, so we have given up and now dedicate a general-purpose register for
thread-local storage on Darwin/x8664.  This reduces foreign-function call overhead substantially.

The Objective-C bridge works on PPC64 now.

Sped up bignum multiplication on 64-bit platforms by multiplying 64-bits at a time (instead of 32).

REBUILD-CCL takes an :update keyword argument;  when T, it will run svn and try to deal correctly
with any conflicts.

On x86 platforms, there is a new debugging feature that allows lisp objects to
be monitored for writes.  See WatchedObjects for documentation.

Updated bundled ASDF.

=== Cocoa IDE ===
The Cocoa IDE has been significantly improved since the 1.3 release.

The IDE will load `home:ccl-ide-init` just before the event loop starts.  See r11998.
