Alberto Cavalcante focused on stabilizing the build toolchain for the JetBrains/hirschgarten repository by updating the Bazel version from 8.1.0 to 8.1.1. This maintenance work targeted improved build reliability and compatibility across continuous integration environments, addressing potential issues with outdated tooling. Using Shell scripting and expertise in build tools, Alberto ensured that the project aligned with the latest stable Bazel release, reducing the risk of flaky builds and simplifying future maintenance. The update was delivered as a single, traceable pull request, emphasizing reproducibility and auditability. Over the month, Alberto concentrated on maintenance rather than new feature development or bug fixes.
