 DATA FILE CHANGELOG
 -------------------
 
+**v0.5.0**
+
+- Updated stimulus presentations tables.
+- Add LFP sample rate when loading from cache.
+- Fixed scaling of LFP data in multiple sessions. Amplitudes were off by a
+  factor of 2 for most ecephys sessions. The scaling is also
+  corrected in released metadata tables.
+    - All ecephys sessions except those listed here had the issue with the
+      LFP amplitude scaling: 1059678195, 1108334384, 1108531612, 1109680280,
