Version 1.2.940

• Update Zstd to 1.4.4
• Update LZ4 to 2.2.1
• Use less memory in caches
• Use bigger sqlite page for Blocks table

Version 1.2.939

• Don't require Cython to run setup
• Fix cythoned build run - define hash_function property early
• Fix compression if minimal_size == -1 (autosize)
• Add default level for auto-compression, fix setup compression auto-level
• Require llfuse >= 0.42 now, prefer 1.x
• Add new action --verify to check all data block hashes

Version 1.2.938

• Update brolti to 1.0.7
• Update zstd to 1.4.0
• Do not allow hard-link to directory
• Lock down database (sqlite) to prevent other operations to damage DB
• Implement --rehash action in do command
• Implement --recompress action in do command

Version 1.2.937

• remove all xxhash code - many hash collisions
• fix support of python-3.2
• add support of pypy3
• fix mutli-thread/process compression
• use binary(64) type for hashes - max 512bit hash can be
• use subvolume ID as name for tables, not hash digest
• fix lzma->xz migration

Version 1.2.936

Quick fix for xz/lzma compression module loading.

DO NOT USE - BROKEN

Version 1.2.935

There is FS version update. And new required module - xxhash.

• use xxHash 32bit for internal hashes in name, subvolume tables
• use xxHash 64bit for data hashes (optional)
• scheme for subvolume and name tables are changed, migration will run
• fixed FS usage report
• fixed DB timings report (verbose stats)
• module ZSTD updated to version 1.3.4

DO NOT USE - BROKEN

Version 1.2.934

• use in block table 8k pages for Sqlite engine
• use new logging class to skip logging ops if verbose level too high (use empty methods)
• don't format log messages in code, use internal logging actions for it
• don't format context object for logging, just log needed data
• optimize write method - don't call metadata hook twice
• more timers for items caching for light profiling
• fix checks for compression methods deprecation and current selection - block may be recompressed by nothing

There is a lot of debug logging optimized / eliminated.
And I suggest some speedup is achieved.

Version 1.2.933

• Update ZSTD compression to v1.3.3
• Fix snapshots removal by "plan"

Version 1.2.932

Umount on SIGTERM right way

Version 1.2.931

• Fix setup compression method and compression level at command line
• Update ArgParser options
