May 2026 monthly summary focused on delivering value through targeted features, critical bug fixes, and strengthened testing and security posture across three repos. Business value was realized via faster, more reliable unbond reporting, improved test fidelity with per-test docker image control, and compliance updates that align with security and licensing expectations. 1) Key features delivered - Vigilante: Implemented Immediate unbonded state reporting for parent staking UTXO. Forward-ported security fix from release/v0.24.x to main to ensure parent spend unbonds immediately when a child stake-expansion has already unbonded. Added optional abort predicates to waitForRequiredDepth to short-circuit when the child unbonds, reducing latency in unbond reporting. (Commits include 64f2fed6017307bb52dc7e88c31555d3c1283abf) - Vigilante: Test environment enhancement to override babylond Docker image per-test, enabling TestStakeExpansionParentUnbondAtOneDeepWhenChildUnbondedEarly against v4.3.0 while the Go SDK remains at v4.2.x. Introduced SetBabylonVersion, WithBabylonVersion, and corresponding test plumbing. (Commit 1302ac0ae1c16742a7e234987825a3c4a66eb799) - Finality-provider: Updated LICENSE to reflect licensor Babylon Labs Limited (commit 4c55d4bea85379da1f69a406185db0e9a745831e). - Babylon: Backported critical security fixes from release/v4.3.x to main, addressing: (a) wrong-epoch vote extension parity with release/v4.4.x, and (b) stake-expansion early-unbond protections. Includes upgrade-handler realignment to release/v4.4.x and accompanying CHANGELOG updates; tests forwarded for coverage. (Commit fe3dd3e8c59a735f73dd531f4a2fac6c4fd2bd2a) 2) Major bugs fixed - Vigilante: Immediate unbonded state reporting for parent UTXO fixed; watchers no longer wait for depth when child has already unbonded. Introduced abort predicates to speed up unbond notifications. - Babylon: Security fixes for wrong-epoch in vote extensions and early unbonding of stake expansions backported and aligned with release/v4.4.x, plus upgrade-handler adjustments and consolidated changelog. - Finality-provider: Licensor information corrected to reflect Babylon Labs Limited. 3) Overall impact and accomplishments - Improved operational reliability and responsiveness in the staking watcher, reducing latency in unbond reporting and improving real-time visibility for validators. - Strengthened security posture by aligning main with release/v4.4.x fixes, reducing exposure to known vulnerabilities in vote extension handling and stake-expansion unbonding flows. - Enhanced testing capabilities and CI coverage by enabling per-test Docker image overrides, accelerating validation of server-side behavior against specific Babylon versions. - Regulatory/licensing compliance updated to reflect correct licensor, mitigating governance and legal risk. 4) Technologies/skills demonstrated - Go, Docker, and containerized test orchestration; per-test environment configuration and version pinning. - Code cherry-picking and backporting across branches to align security fixes with current main. - Upgrade-handler realignment and CHANGELOG governance to reflect security and feature parity with release tracks. - E2E testing enhancements and test scaffolding for scenario-based validation.
