Apr 1, 2026April 2026 – islet-project/islet monthly summary focusing on build stability and compatibility improvements. No new user-facing features in this period; primary effort was a targeted dependency cleanup to simplify the build pipeline. The SWTPM dependency was removed by updating the tf-a-rss and optee-build submodules to align with the current build environment, reducing cross-dependency fragility and CI risk.

Aug 1, 2025August 2025 (islet project) monthly summary: Delivered key security and platform enhancements for RMM 1.0-rel0, stabilized the build pipeline, and advanced HES/TF-A/PSA integration. Notable outcomes include updated attestation token format with realm profile claim, re-enabled SDK compilation to restore CI reliability, and platform token hashing improvements with updated submodules and PSA protocol adjustments. Completed code hygiene (cargo fmt across hes) and alignment of submodules with 1.0-rel0 requirements. These efforts reduce token processing risk, accelerate feature delivery, improve platform interoperability, and lower build friction across the repository.
