Announcing python-blosc 1.0.5
What is it?
A Python wrapper for the Blosc compression library.
Blosc (http://blosc.pytables.org) is a high performance compressor
optimized for binary data. It has been designed to transmit data to
the processor cache faster than the traditional, non-compressed,
direct memory fetch approach via a memcpy() OS call.
Blosc works well for compressing numerical arrays that contains data
with relatively low entropy, like sparse data, time series, grids with
regular-spaced values, etc.
python-blosc is a Python package that wraps it.
What is new?
- Upgraded to latest Blosc 1.1.4.
- Better handling of condition errors, and improved memory releasing in
case of errors (thanks to Valentin Haenel and Han Genuit).
- Better handling of types (should compile without warning now, at least
