- Update to version 1.19.0:
* The length of automatic blocksizes for fast codecs (lz4, blosclz) has been incremented quite a bit (up to 256 KB) for better compression ratios.
* The performance in modern CPUs (with at least 256 KB in L2 cache) should be better too (for older CPUs the performance should stay roughly the same).
* For small buffers that cannot be compressed (typically < 128 bytes), blosc_compress() returns now a 0 (cannot compress) instead of a negative number (internal error). See #294.
* blosclz codec updated to 2.1.0. Expect better compression ratios and performance in a wider variety of scenarios.
* blosc_decompress_unsafe(), blosc_decompress_ctx_unsafe() and blosc_getitem_unsafe() have been removed because they are dangerous and after latest improvements, they should not be used in production.
