 # Changelog
 
+## v0.5.0
+
+This release includes code merging from the upstream version v1.7.7 along with several fixs and improvements. Fjord fork from upstream is included and will be activated on opBNB testnet in later release.
+
+### User Facing Changes
+
+* New flag `--wait-node-sync` added to op-batcher (default false), indicates if during startup, the batcher should wait for a recent batcher tx on L1 to finalize (via more block confirmations). This should help avoid duplicate batcher txs
+* New flag `--wait-node-sync` added to op-proposer (default false), indicates if during startup, the proposer should wait for the rollup node to sync to the current L1 tip before proceeding with its driver loop
+* New flag `--compression-algo` added to op-batcher (default zlib), user can choose brotli algo after Fjord fork
+* New flag `--l1.rpc-max-cache-size` added to op-node (default 1000), so user can config the the maximum cache size of the L1 client
