February 2025 achievements for gravitational/teleport: Introduced CredentialLifetime struct enabling per-output TTL (credential_ttl) and renewal_interval customization across services and outputs; deprecates certificate_ttl in favor of credential_ttl to standardize TTL semantics and improve policy consistency across environments. Implemented in the Teleport repo with a focused commit to enhance per-output credential management.

Month 2024-10: Focused on security maintenance and dependency hygiene in temporalio/sdk-python. Delivered a critical security patch by upgrading tonic to v0.12.3 and updating rustls-native-certs and tokio-stream, with Cargo.lock refreshed to ensure reproducible builds. The change, recorded in commit 0b327b04a95fc7954ed2c9e4e1a6c5de47c51ebd ("Upgrade tonic to v0.12.3 to fix security vulnerability (#680)"), mitigates known vulnerabilities and preserves compatibility. This work reduces risk, supports secure CI/CD, and maintains reliability for downstream users dependent on the Python SDK.
