- The --no_default_filters option of para_filter has been
removed.
- Several fixes and latency improvements to various decoders.
+ - The alsa writer now limits the prebuffer time to 500ms.
- Documentation improvements.
+ - Overhaul of the command_util.sh script.
+ - Fixes for some minor problems found by the clang analyzer.
+ - Compiles (almost) without warnings on gcc-3.
