April 2026 — Livebook development: stabilized release pipelines, modernized dependencies, and improved Windows desktop UX, while fixing a startup race condition. These changes reduce release risk, improve deployment reliability, and enhance end-user install/initialization experience, enabling faster, more predictable releases. Key features delivered: - CI/CD and Build Reliability Improvements: Stabilized the CI/CD pipeline by pinning trusted-signing-cli to version 0.9.0, updating workflow dependencies (actions/checkout@v6), and removing OpenSSL references from CI config. Commits: Use trusted-signing-cli@0.9.0; Use actions/checkout@v6; Remove openssl from ./versions. - ElixirKit Dependency Upgrades: Upgraded ElixirKit dependencies to the latest versions to improve compatibility and unlock new features. Commits: Update elixirkit (x3). - Desktop Build and Installer UX Enhancements: Improved Windows/desktop build and installation UX, including updated docs, a Windows installer icon, and improved Notepad handling under WSL. Commits: Update README.md; Fix opening files on Windows; Add Windows installer icon. - Release Packaging Enhancements: Reintroduced standalone.exs to ensure essential components are copied into the release directory, improving deployment reliability. Commits: Bring back rel/app/standalone.exs. Major bugs fixed: - Single-Instance Plugin Initialization Bug Fix: Ensure the single-instance plugin initializes first to reliably manage application instances and prevent multiple concurrent instances. Commit: Fix plugin order, tauri_plugin_single_instance should be first. Overall impact and accomplishments: - Reduced release risk with a more reliable CI/CD pipeline and updated tooling, enabling faster, more predictable releases. - Improved deployment reliability and end-user install experience on Windows desktop, including better Notepad behavior under WSL and a polished installer identity. - Strengthened startup determinism by enforcing correct plugin initialization order, eliminating race conditions that could spawn multiple instances. Technologies and skills demonstrated: - CI/CD optimization (GitHub Actions, version pinning, workflow dependency management) - Dependency management and ecosystem upgrades (ElixirKit) - Windows desktop build and installer UX, including WSL integration - Release packaging and deployment reliability, including standalone resources - Runtime startup correctness and plugin initialization sequencing

February 2025: Delivered reliability and developer-experience improvements across Livebook, Erlang.org, and OTP. Key features include increasing the OTP bootstrapping file descriptor limit to improve build stability in complex environments; streamlined local Livebook Desktop testing by deregistering the globally installed app from LaunchServices and enabling non-admin registry testing; and documentation improvements for erts/OTP noting that process_info/1 parent is available since OTP 25.0 and reorganizing CLI options so the 'Since' information follows option descriptions. Major bug fix: corrected the News Item release date in erlang-org to accurately reflect 2025-02-12. Overall impact includes more robust builds, easier local testing, and clearer developer guidance across the Erlang/OTP ecosystem.

In 2025-01, erlang/otp delivered packaging hygiene improvements for Windows ZIP artifacts and stabilized the Windows build workflow. Implemented a robust cleanup step that removes obsolete erl.ini files from erts-* directories before archiving into otp*.zip, refactored to use PowerShell cmdlets for reliability, and fixed the CI workflow to ensure consistent Windows ZIP uploads.
