Apache Portable Runtime Utility (APR-util) 1.6.3 Released The Apache Software Foundation and the Apache Portable Runtime Project are proud to announce the General Availability of version 1.6.3 of the Apache Portable Runtime Utility library (APR-util). For detailed changes in this maintenance release, see; https://www.apache.org/dist/apr/CHANGES-APR-UTIL-1.6 APR, APR-util and APR-iconv are available for download from: https://apr.apache.org/download.cgi In APR-util 1.6.0 and later, there are a number of specific changes in how APR is deployed which may be disruptive to existing build strategies: - Expat sources are no longer bundled, this is now an external dependency. Install libexpat runtime (usually installed by default) and development packages using your system's package manager, or from . - MySQL support is updated as advised by the MySQL developers. MySQL versions older than 5.5 should not be used. If you do use an old MySQL version, use the thread-safe libmysqlclient_r version of the library. - FreeTDS partial and incomplete support has been dropped. Users of MSSQL and SYBASE databases are recommended to use the ODBC driver instead. 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!
