Worked on the mapbox/mapbox-search-android repository to deliver an SDK release candidate upgrade to version 2.12.0-rc.1, focusing on release management and version control. The work involved updating version numbers consistently across CHANGELOG.md, gradle.properties, and versions.gradle, ensuring that all dependencies and build configurations were properly aligned for the new release. Using Gradle as the primary build tool, the developer emphasized traceability and documentation to support downstream QA and validation. This release-engineering effort established stable, predictable builds and streamlined the release process, enabling Android applications that depend on the Mapbox SDK to benefit from faster, more reliable release cycles.
