April 2026: Delivered Language Server support for aliased imports reference finding in gleam-lang/gleam. This feature enables reliable reference resolution for aliased imports (functions, constants, and types), improving code navigation and refactoring confidence. Added end-to-end tests covering aliased imports across functions, constants, and types to ensure correct reference resolution when items are imported with aliases. Updated the changelog with an example illustrating usage. Implementation traced through two commits: 82c7d58d22a789c36da05694e55c1ff335f332bc (Support finding references from aliased import) and 76f968681789e744dddcfd248fa78707f22da2b9 (Add example to changelog).
