Jun 1, 2026June 2026 (2026-06) summary for nimiq/core-rs-albatross: Focused on release readiness, stability, and performance across core Rust components, web client, and network governance. Delivered multi-version release prep (v1.6.0 and v1.6.1) with updates to web client package.json and workspace versions, plus groundwork for v1.7.0/v1.7.1 releases. Implemented cross-platform build reliability improvements (web client: wasm-opt for host platform) and improved client visibility (exposed getVersion endpoint) with pico as the default sync mode. Updated testnet genesis and mainnet checkpoint blocks to ensure reliable restart and sync initialization. Introduced a per-fork upgrade activation registry to support policy-driven upgrades. Hardened validator and consensus paths with performance optimizations (hash-to-G1 caching) and key bug fixes (version-upgrade trigger, modulo-by-zero guard, MMR proof termination, and several RPC/CLI and logging improvements).

May 1, 2026May 2026 — nimiq/core-rs-albatross monthly summary. Key features delivered: - Release versioning alignment for v1.5.x: prepared code for v1.5.0/v1.5.1; synchronized workspace/package.json across components for release readiness. Major bugs fixed: - Web client build stability: pinned wasm-bindgen and updated CI to install the correct pre-built dependency version, reducing web build failures (commit 5521b790...). - Live-sync and network verification hardening: early header validation and strengthened block verification to ensure blocks match requests and to ban malicious peers (commits c9c900c4... and c289e81c...). - Validator safety: overflow protection and robust handling of invalid validator sets; replaced overflow-prone addition with checked_add and added regression tests (commits 6354f260... and 6a97b94a...). - Removed panicking assertions in Validators::hash: deterministic behavior for malformed inputs and regression tests (part of 6a97b94a...). Overall impact and accomplishments: - Increased build reliability and CI confidence; improved release readiness for v1.5.x; hardened sync path and validator data handling, reducing potential node panics and security risk. - Demonstrated robust cross-component coordination (web client, core RS, and network protocol). Technologies/skills demonstrated: - Rust and wasm-bindgen, CI automation, release tooling, regression testing, overflow-safe arithmetic, network protocol hardening, and robust validator/data verification.

Nov 1, 2024November 2024 was a focused month of release readiness, stability, and dependency modernization for the core-rs-albatross repository. Key outcomes include structured release prep for v1.0.0-rc.1 through rc.4 and automation-enhanced release processes for subsequent versions, a PoW migration refresh with history reversion logic and updated PoW client integration, and the reintroduction of accounts diff pruning to optimize state handling. In addition, mainnet readiness was improved via configuration updates and seed-node adjustments along with an env variable rename for clarity. The team also modernized dependencies (nimiq-jsonrpc crates) and hardened builds by updating minimum versions and ensuring deterministic builds with an updated Cargo.lock. These efforts deliver faster, safer releases, more stable network operations, and a stronger foundation for future work.
