Apache Portable Runtime 1.2.8 (and Legacy 0.9.13) Versions Released
The Apache Software Foundation and the Apache Portable Runtime
Project are proud to announce the General Availability of
version 1.2.8 of the Apache Portable Runtime, APR, and version
1.2.8 of it's companion project, the Apache Portable Utility
library APR-util. A corresponding version of APR-iconv 1.1.1
an alternative portable implementation of the 'iconv' library,
is available for users without a system iconv implementation.
APR is available for download from:
http://apr.apache.org/download.cgi
This version of APR is principally a bug fix release, including
fixes for specific platforms' configuration, feature detection,
and run time behavior. Most developers are encouraged to adopt
the latest APR 1.x version to ensure the most comprehensive
support and access to the latest features and enhancements.
Version 0.9.13 of the Apache Portable Runtime, APR, and version
0.9.13 of it's companion project, the Apache Portable Utility
library APR-util are also now released and available for legacy
users. A corresponding version of APR-iconv 0.9.7, an alternative
portable implementation of the 'iconv' library, is available for
users without a system iconv implementation.
The mission of the Apache Portable Runtime Project is to create
and maintain software libraries that provide a predictable and
consistent interface to underlying platform-specific
implementations. The primary goal is to provide an API to
which software developers may code and be assured of predictable
if not identical behavior regardless of the platform on which
their software is built, relieving them of the need to code
special-case conditions to work around or take advantage of
platform-specific deficiencies or features.
APR and its companion libraries are implemented entirely in C
and provide a common programming interface across a wide variety
of operating system platforms without sacrificing performance.
Currently supported platforms include:
UNIX variants
Windows
Netware
Mac OS X
OS/2
To give a brief overview, the primary core
subsystems of APR 1.2 include the following:
Atomic operations
Dynamic Shared Object loading
File I/O
Locks (mutexes, condition variables, etc)
Memory management (high performance allocators)
Memory-mapped files
Multicast Sockets
Network I/O
Shared memory
Thread and Process management
Various data structures (tables, hashes, priority queues, etc)

Users of APR 0.9 should be aware that migrating to the APR 1.x
programming interfaces may require some adjustments; APR 1.x is
neither source nor binary compatible with earlier APR 0.9 releases.
Users of APR 1.x can expect consistent interfaces and binary backwards
compatibility throughout the entire APR 1.x release cycle, as defined
in our versioning rules:
http://apr.apache.org/versioning.html
APR is already used extensively by the Apache HTTP Server
version 2 and the Subversion revision control system, to
name but a few. We list all known projects using APR at
http://apr.apache.org/projects.html -- so please let us know
if you find our libraries useful in your own projects!
