• Compare: v0.5.14...v0.5.15

• Date range: 2025-10-14 → 2025-11-11

• Stats: 233 files changed, +12821 / −6086

• Top impact areas: validator (42), e2e-tests (17), docker (13), db_utils (10), db_core (10), sdk (9), network (8), examples (8), bootnode (8), state-sync (7), structs (6), config-params (6), token (5), snapshot-manager (5), runtime (5), local_validator (5), common (5), bitcoin-internal (5), transaction_pool (4), telemetry (4)

Highlights

• Validator and state sync: Stability and performance improvements across validation paths and state synchronization routines.

• Testing: Expanded e2e coverage and flake reductions to harden CI and release quality.

• Infra and packaging: Docker and build updates for more repeatable, slimmer artifacts and faster local/dev cycles.

• SDK: Iterative enhancements and fixes improving client ergonomics and correctness.

• Storage and DB: Targeted tuning and fixes in db_core/db_utils to stabilize I/O and throughput.

Added

• New e2e scenarios and utilities to improve regression coverage.

• Additional telemetry signals to aid runtime and network visibility.

• Docker/build improvements for local validator and release images.

• SDK helpers and types to streamline common client operations.

Changed

• Refactors in validator critical paths for clarity and maintainability.

• db_core/db_utils adjustments for safer defaults and better performance under load.

• Configuration updates in config-params with improved validation and defaults.

• Networking and bootnode tweaks to improve startup and peer handling.

• Adopted Speedb as the embedded storage engine and deprecated RocksDB; on-disk format remains compatible and no data migration is required.

Fixed

• Snapshot manager stability issues observed under concurrent workloads.

• Intermittent validator edge cases during high-throughput apply-block flows.

• Flaky e2e tests and minor race conditions in async task lifecycles.

• Miscellaneous correctness fixes across runtime, token, and transaction_pool.

Performance and Observability

• Reduced tail latencies in validator hot paths and steadier state-sync throughput.

• Enriched metrics for network/validator subsystems to aid debugging and capacity planning.

RPC and API Changes

• No breaking RPC changes.

• Minor SDK ergonomics and type improvements for downstream consumers.

Breaking Changes

• None known.

Migration Guidance

• No action required for node operators.

• Consumers can adopt the latest SDK changes at their convenience; no config changes required.

Documentation

• Updated references for Docker workflows, local validator usage, and expanded e2e/testing guidance.
