+- bump: minor
+  changes:
+    added:
+    - Support for 2024 CPS ASEC data (March 2024 survey)
+    - CensusCPS_2024 class to download raw 2024 ASEC data
+    - CPS_2024 class using actual 2024 data instead of extrapolation
+    - CPS_2025 class with extrapolation from 2024 data
+    - DOCS_FOLDER constant to storage module for cleaner file paths
+    - Tests for CPS 2024 and 2025 datasets
+    changed:
+    - Fixed __file__ NameError in interactive Python environments
+    - Updated generate method to handle 2025 extrapolation from 2024
