+## 3.0a5
+
+### Improvements
+- Added missing fmi3 import functions for CAPI calls:
+    - `fmi3_import_get_shift_decimal` for `fmi3GetShiftDecimal`.
+    - `fmi3_import_get_shift_fraction` for `fmi3GetShiftFraction`.
+    - `fmi3_import_set_shift_decimal` for `fmiSetShiftDecimal`.
+    - `fmi3_import_set_shift_fraction` for `fmiSetShiftFraction`.
+
+### Changes
+
+- [BREAKING] Removed unused `instanceEnvironment` and `logMessage` inputs from `fmi3_import_instantiate_*` functions.
+    - The corresponding CAPI calls use `instanceEnvironment` and `logMessage` from `fmi3_import_create_dllfmu`.
+
+### Bug fixes
+- Fixed an issue where enum variables min/max attributes were incorrectly handled as `int32`, instead of `int64`.
+    - [BREAKING] Changed return types of `fmi3_import_get_enum_variable_min` and `fmi3_import_get_enum_variable_max` from `int` to `fmi3_int64_t`.
+- For FMI3, added a missing trailing file separator to `resourcePath`.
+- For FMI3, removed `file` URI prefix for `resourcePath`.
+
+### Improvements
+
+- Fixed crash when calling `fmi3_import_collect_model_counts` and the model contained Binary or Clock variables.
