abcl-1.3.0 is a feature release.
15-MAR-2014
## Features
* Make LispStackFrame.UNAVAILABLE_ARG a singleton object,
and lazily create the little used portions of the Lisp stack.
Aggressively cache and control the use of memory by the underlying
Lisp stack frame representation by introducing the private
LispThread.StackFrame and LispThread.StackSegments classes.
Contributed by Dmitry Nadezhin.
LispStackFrame object are allocated on every
LispThread.execute(...) . However, they are seldom [accessed]
([... verify via] inspect[tion of the] stack trace). This patch
delays allocation of LispStackFrame? objects until they are
requested. Raw information about stack frames is stored in
stack. Stack is an Object[] array (more precisely a list of [...]4
[Mib] Object[] arrays).
ME: We are going to need a way to try to less agressively grab 4Mib
chunks in low memory situations.
Memory profiling of ABCL shows that the classes with largest
allocation count are org.armedbear.lisp.LispStackFrame and
org.armedbear.lisp.LispStackFrame.UnavailableArgument.

* ASDF 3.0.1.94 shipped with the implementation
* per function call stack and memory exception handler in CL:COMPILE
Inline calls to jrun-exception-protected (used by handler-bind to
catch out of memory conditions). This commit saves generation
roughly 50 cls files.

* SYS:SHA256 audited
The functionality if the SYS:SHA256 algorithim has been audited for
use on inputs of single for files with recently shipping ORCL Java 7
implementations (through jdk-1.7.0_51).

* Connect to NetBeans controlled JDWP via SLIME
The Netbeans IDE configuration now includes a way to connect to
the running-under-jdb ABCL via SLIME. One needs a version of
SLIME able to be loaded from its 'swank.asd' definition.
* Install 'abcl.jar' and 'abcl-contrib.jar' locally as Maven artifacts
The Ant `abcl.mvn.install` target now installs build artifacts
into the local Maven repository (Olof-Joachim Frahm)

## Compatibility
* CL:DIRECTORY
The implementation specific :RESOLVE-SYMLINKS argument to the ANSI
DIRECTORY function has been changed to nil. This implements
behavior closer to SBCL and guarantees that a DIRECTORY operation
will not signal a file error.

## Fixes
* Fix CL:SLEEP for intervals less than a millisecond.
For intervals less than or equal to a nanosecond, including an
interval of zero, the current thread merely yields execution to
other threads.

## Tested
### "Java_HotSpot(TM)_64-Bit_Server_VM-Oracle_Corporation-1.7.0_51-b13" "x86_64-Mac_OS_X-10.9.1"
### "Java_HotSpot(TM)_64-Bit_Server_VM-Oracle_Corporation-1.8.0-b129" "x86_64-Mac_OS_X-10.9.2"
## Contrib
#### abcl-asdf
* Now working with both Maven 3.0.x and 3.1.x. Thanks to Anton for
the help!

* cache Maven dependency resolution to avoid repeated lookups.
Instead of calling ABCL-ASDF:RESOLVE in both the ASDF COMPILE-OP
and LOAD-OP, we now cache the result of invocation in COMPILE-OP
and add this value in the LOAD-OP phase. Contributed by Cyrus
Harmon.

#### jna
Now references jna-4.0.0. Some incompatibility with CFFI ([in
progress with fixing upstream][cffi-easye]).
