 ### Fixed
 
-- Fix `get_or_insert_with` and `get_or_try_insert_with` methods in `future::Cache`
-  can lead undefined behavior as accepting `init` future that is not `Send` or
-  `'static`. ([#31][gh-issue-0031])
+- Fix a bug in `get_or_insert_with` and `get_or_try_insert_with` methods of
+  `future::Cache` by adding missing bounds `Send` and `'static` to the `init`
+  future. Without this fix, these methods will accept non-`Send` or
+  non-`'static` future and may cause undefined behavior.
+  ([#31][gh-issue-0031])
 - Fix `usize` overflow on big cache capacity. ([#28][gh-pull-0028])
 
 ### Added
 
 - Add examples for `get_or_insert_with` and `get_or_try_insert_with`
   methods to the docs. ([#30][gh-pull-0030])
 
+### Changed
+
+- Downgrade crossbeam-epoch used in moka-cht from v0.9.x to v0.8.x as a possible
+  workaround for segmentation faults on many-core CPU machines.
