v0.3.0

A new version has arrived!
This version have a few new things:

• Using Indirect Context Modelling for the Secondary Context.
• Modifying the counter of the Primary Context.
• Added a few Rust #[inline] and #[cold] magic tricks to help the compiler optimize the binary better.

All those changes resulted in about 5-10% faster in compression speed. The decompression speed and the compression ratio should stay the same.

WARNING: this is a format breaking change!

v0.2.1

This release fixed the deadlock problem on the previous version. IO are now handled by other threads, that should make the compression/decompression a bit faster.

v0.2.0

Compared to v0.1.2:

• Added file header.
• Use threads more efficient, faster compression.
• Change Arithmetic Coding from 64 bit to 32 bit.
