 # Changelog
 
+##
+## [0.15.5] - 2025-06-04
+
+### Added
+
+- `classFqn` helper to compute fully-qualified names
+- import-filter to drop any illegal import strings
+- `typeRef` helper to pick simple name or FQN and avoid duplicates
+- `lastSegment` helper to filter out a context’s own class from imports
+
+### Changed
+
+- Updated `ResolvedContext.hbs` so that all generated-type references go through `typeRef` (simple names only when safe)
+- Updated constructor loops in `ResolvedContext.hbs` to call proxy methods with `classFqn` (true FQNs)
+
+### Fixed
+
+- “already defined in this compilation unit” compile errors—SDK now builds without name collisions
