Apache Portable Runtime 1.7.4 Released

The Apache Software Foundation and the Apache Portable Runtime Project are proud to announce the General Availability of version 1.7.4 of the Apache Portable Runtime library (APR).

In APR 1.7.0 and later, there are a number of specific changes in how APR is deployed which may be disruptive to existing build strategies:

• The typical cross-process locking stragegy now defaults to a pthreads lock which will not leak on abnormal process termination, as opposed to the earlier sysv semaphore locking strategy. This should result in fewer orphaned locks in misbehaving applications.
• Netware users should be aware that APR mis-defined the entity representing an "os mutex", and it was missing a level of indirection. The new definition should allow the use of the apr_os_proc_mutex_get/_put API's on the Netware platform but requires a rebuild against the APR 1.7.0 or later library.

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. We list all known projects using APR at https://apr.apache.org/projects.html - so please let us know if you find our libraries useful in your own projects!
