Version 1.2.952

• update zstd to 1.5.5
• update lz4 to 1.9.4
• update llfuse to 1.4.2
• update recordclass to 0.18.3
• removed old/unsupported compression methods 💣
• add common/clustered data storage of blocks, to store them across backup nodes

Version 1.2.951

• Fix report statictics output
• Fix xz load
• Fix brotli extra optimization
• New option for detailed statistic
• Update DB schema - remove unused indexes
• Update cython build

Version 1.2.950

• update zstd to 1.5.0
• fix lz4 module build
• make sqlite shrink memory
• rewrite recompress and rehash to use less memory
• adjust compression levels
• add more hash algos for python3.6+

Version 1.2.949

• Update zstd to 1.4.9
• Update brotli to 1.0.9
• Fix mysql startup options to be compatible with MariaDB 10.5
• Update options for InnoDB, TokuDB, RocksDB

Version 1.2.948

• Update zstd to 1.4.5
• Use new algo for median calculation
• Speedup a little dump-load vacuum

Version 1.2.947

• Use mean compressed written block size for sqlite block-table page_size. This should make table smaller after vacuum
• Store last vacuum datetime in option table
• Add new command-line option for vacuum action - --vacuum-if-last-time-more-than-days. This should allow run vacuum everyday, but actually do it only if last vacuum was X days ago.

Version 1.2.946

• Fix long standing bug with do --list-subvol
• Show freed space after subvol/snapshot removal (-vv needed)
• Adjust caches expire times (make lower) - too much memory used, don't really needed
• Rewrite caching time calculation - like for database tables
• Disable cache and table timers by default, unless verbosity level >= INFO (-vv).
  Which saves about 9% run time.

• Moved garbage collector code from Operations class to separate defragment do-action file
• Added two more caches for hash-size and hash-compression-type values - more memory consumed now
• Reduce a little names cache memory usage
• Recalculate block table page_size (sqlite) before vacuum starts
• Return support for python-3.4, use recordclass <= 0.12.1 or >= 0.13.0.1
• Use less imports for names and subvol tables
• Make verbose output of vacuum and defragment do-actions more parsable with --parsable
• Increased cache timeouts - more memory consumed now
