 - Repositories in the "authenticated" mode are now treated as the unencrypted
   repositories they are.
 
+- The client-side temporary repository cache now holds unencrypted data for better speed.
+
+- borg init: removed the short form of --append-only (-a).
+
+- borg upgrade: removed the short form of --inplace (-i).
 
 New features:
 
-- integrity checking for important files used by borg:
+- reimplemented the RepositoryCache, size-limited caching of decrypted repo
+  contents, integrity checked via xxh64. #2515
+- reduced space usage of chunks.archive.d. Existing caches are migrated during
+  a cache sync. #235 #2638
+- integrity checking using xxh64 for important files used by borg, #1101:
 
   - repository: index and hints files
-  - cache: chunks and files caches, archive.chunks.d
+  - cache: chunks and files caches, chunks.archive.d
+- improve cache sync speed, #1729
+- create: new --no-cache-sync option
+- add repository mandatory feature flags infrastructure, #1806
 - Verify most operations against SecurityManager. Location, manifest timestamp
   and key types are now checked for almost all non-debug commands. #2487
 - implement storage quotas, #2517

 - borg export-tar, #2519
 - list: --json-lines instead of --json for archive contents, #2439

+- normalize authenticated key modes for better naming consistency:
+
+  - rename "authenticated" to "authenticated-blake2" (uses blake2b)
