ShutterDB v0.2.0

ShutterDB v0.2.0

Persistent binary caches for C++20.

Changes

• shutter::Cache: LRU eviction, automatic compaction and hit/miss statistics. The
  default budget for the main file is 1 GiB; call sync() to synchronize buffered writes.
• Buffered log scanning: a reusable read window and index updates in place reduce
  reads and allocations during opening and verification.
• Runtime-detected x86-64 CRC32C acceleration, a portable fallback and one-buffer
  indexed reads.
• PNG/JPEG preview caching with transparency and content-hash reuse across filenames
  and process restarts.
• SQLite and RocksDB benchmarks covering ingestion, reads, updates and compaction
  on 64 MiB and 1 GiB datasets.

Upgrade

Format v1 is unchanged; existing databases need no migration. DB keeps synchronous
writes by default. Cache uses the same format and evicts entries to meet its budget.

The core library and CLI build without third-party dependencies. The optional image example
requires OpenSSL, libpng 1.6+ and libjpeg.
