Crab v1.2.4

S3 Gateway

• Completed conditional mutation support and accepted empty list delimiters for
  broader S3 client compatibility.
• Added configurable Git blob thresholds, bounded sustained request
  amplification, and expanded ecosystem and large-repository qualification.

Git And Durability

• Preserved Git visibility while restoring flat incremental-push latency and
  reducing object-store requests.
• Rebuilt missing Git object-locator sidecars and made concurrent prepared-xorb
  publication converge safely on the winning durable result.
• Recovered native pushes from durable receipts after interrupted HTTP receive
  operations.

Hosting And Repository Experience

• Added durable multi-cloud deployment support, a one-command Compose stack,
  and readiness protection during server drain.
• Added richer blame and discussion views, format-aware file previews, and an
  interactive data workbench for repository content.

SQLite Replication

• Added the crab-ltx crate for checksum-verified SQLite WAL capture,
  replication, sparse storage, recovery, and compaction.

Crab v1.2.3

S3 And Reliability

• Hardened S3-compatible streaming, burst-load handling, and large-object
  clone paths.
• Added bounded response-stream idle handling and expanded gateway metrics,
  deployment, and qualification coverage.

Git And Performance

• Reduced clone latency by overlapping catalog scans with pack transfer.
• Kept incremental push latency flat during owner maintenance by caching
  immutable ref transactions and reusing unchanged repository snapshots.

Rust SDK

• Unified the public repository API and aligned executable capability versions.
• Completed workflow and recovery qualification and replaced SDK README
  snippets with compilable examples.

Crab v1.2.2

Git And Progress

• Added live progress reporting for clone and large-push operations, including
  Git pack counts, transferred bytes, and transfer rates.
• Improved interactive and JSONL output so long-running Git operations expose
  their current phase instead of appearing stalled.
• Documented clone and push progress events and their structured fields.

Crab v1.2.1

SDK And S3

• Delivered the complete Rust SDK for local and remote repository workflows,
  including clone, fetch, push, recovery, and qualification coverage.
• Added the S3 gateway service with streaming and multipart object operations.
• Expanded S3-compatible read and write paths with selective range handling and
  foreground-write scheduling.

Git And Performance

• Accelerated large-repository clones and kept incremental push latency bounded.
• Improved first-time push guidance when a repository has no initialized
  remote.

Crab v1.2.0

Git And Large Files

• Hardened resumable uploads, bounded push publication, native Git
  compatibility, and mirror reconciliation.
• Reduced add and edited-push latency with larger classification batches,
  cached preparation, paged deduplication, and batched staging retirement.
• Batched previsibility index publication and tightened data integrity,
  cleanup, and diagnostic contracts across shared crates.

Hosting And Cache

• Added authenticated Git hosting and repository collaboration.
• Consolidated canonical reads and hardened local cache behavior.
• Hardened the macOS NFS mount lifecycle.

Documentation

• Standardized repository object-store layout documentation, moved the
  pointer specification to crab.build, and refreshed embedded agent skills.
• Published the Kubernetes RustFS benchmark and Rust SDK design plan.

Crab v1.0.1

Push And Large Files

• Published large-file indexes before refs so newly pushed file versions are
  visible to readers only after their index data is available.
• Bounded metadata shard replay and isolated reconstruction cancellation to
  prevent large repositories or one failed file from exhausting a push or
  hydrate operation.
