Version 3.13.0 is a minor release of FTimes. Generally, code was cleaned up and refined as necessary. Several bugs have been fixed -- see the ChangeLog for details. The most significant changes in this release are the addition of new encoder/decoder/embedded routines, support for B-Tree file systems (BTRFS) under Linux, and the introduction of KLEL-based include/exclude filters. Note that both PCRE and KLEL (1.2.0 or higher) libraries are now required. For now, PCRE-base filters are still enabled by default, but the plan is to phase them out completely in a future release.
