Updated FLAC to version 1.2.0
It will be slightly faster on Intel Macs due to enabling MMX/SSE codes.
Partially rewritten Monkey's Audio/TTA decoder with SSE optimization
Notes: TTA version 3.4.1 has been released, but it has no improvement on decoder and lost 32bit float decoding capability. So XLD still uses version 3.3.
Fixed overwriting problem when both input and output file have the same name (GUI)

# (Nov. 13, 2007 19:00 GMT)Updated again because VBR quality is not saved
# Supported ABR and unconstrained(true) VBR mode in AAC encoder (GUI)
The new AAC encoder is available on Leopard, or Tiger with QuickTime 7.3 installed. Here is a brief explanation of available modes:
* CBR
* Keep a bitrate constant, but it is not perfectly constant due to a bit reservoir. ABR
* Try to encode at a target bitrate on an average. It fluctuates bitrate locally more than CBR because bitrate restriction is applied in a longer time span compared to CBR. VBR (Constrained)
* Fluctuates bitrate according to the difficulty of encoding. It constrains variation range due to the target bitrate. So It doesn't fully take advantage of VBR feature, but more efficient than ABR. Older version of XLD and iTunes use this as VBR mode. True VBR
Fluctuates bitrate according to the difficulty of encoding to maintain a target quality. Bitrate variation is unconstrained. Theoretically it provides the best tradeoff between quality and bitrate, but bitrate is hard to predict. Apple's implementation requires target quality in 0 to 127 range. As a guide, quality 0 is about 32kbps, 90 is about 128kbps, and 127 is about 192kbps, respectively.
# True VBR mode requires target quality, and the others require target bitrate. Unlike the previous version, the target bitrate can be specified at any value in 16-320kbps. Added Simplified Chinese localization (GUI)
Thanks to Shonete Smith.

Added support for HE-AAC output by aacplusenc
Supported bitrate range is 16-64kbps. Parametric stereo is used if bitrate <= 44kbps. Supported input frequency is 32, 44.1 and 48kHz.
For high-quality playback, use MPlayer or VLC. AAC decoders based on QuickTime cannot handle SBR and PS part.
Integrated MP3 decoder
Still no support for ID3 reading.
Fixed bug that caused crash when Raw PCM import
