January 2026: Security hardening of dependency verification for dropwizard/dropwizard. Re-enabled the PGP verification plugin in the Maven build and added a centralized mechanism to manage trusted and revoked dependencies. Introduced a revoked-keys map and a new PGP key mappings file to streamline key rotation and remediation. Commit 1325959dff0b66f402bd176e992c318dd868bdc3 documents the plugin re-enable (#11000). Impact: reduces risk of tampered or unsigned transitive dependencies, improves build reproducibility, and supports faster vulnerability remediation.

Jan 1, 2025

January 2025 monthly summary focusing on reliability, API safety, and feature delivery across two repositories: dropwizard/dropwizard and clerk/clerk-sdk-go. Delivered internal quality and stability improvements in Dropwizard (test refactor with AssertJ, migration from Checker Framework to JSpecify for consistent null-safety annotations, and API clarity improvement by removing Nullable from CacheLoader return to guarantee non-null Class<?> from createProxyClass). In Clerk SDK-Go, added user creation controls and organization creation limits, including updating CreateOrganizationsLimit to int to support numerical limits. These changes deliver improved test reliability, API safety, granular user/organization management, and maintainable APIs without user-facing behavior changes.
