<p>This new release brings many significant improvements. The quality has been improved, both at the encoder level and the decoder level. These include enhancer improvements (now on by default), input/output high-pass filters, as well as fixing minor regressions in previous 1.1.x releases. A strange and rare instability problem with pure sinusoids has also been fixed. On top of that, memory use has been greatly reduced, especially for fixed-point and narrowband. The fixed-point narrowband encoder+decoder memory use has been cut by more than half, making it possible to fit both in less than 6 kB of RAM. In general, CPU requirement had gone down, especially for the fixed-point port. The Blackfin port has been speeded up significantly, thanks to David Rowe. There are also a few fixes for the TI C5X DSPs, as well as better support for C++ compilers and crappy MS compilers. Oh, and before anyone starts worrying, the format (bit-stream) itself has not changed, so Speex is still co
mpatible with version 1.0 and will continue to be in the future.</p>
