# Experimental: This is a new format for release notes. The format and availability is subject to change. ## 2021.2.3 ### Backward Incompatible Changes [db-connect] Removes db-connect from `cloudflared`. The Cloudflare Workers product will continue to support db-connect implementations with versions of `cloudflared` that predate this release and include support for db-connect. ### New Features [TCP connects] Introduces support for proxy configurations with websockets in arbitrary TCP connections (#318) ### Improvements [command line interface] Nested commands (such as cloudflared tunnel run) now consider CLI arguments even if they appear earlier in the command. E.g. `cloudflared --config config.yaml tunnel run` will now behave similarly to `cloudflared tunnel --config config.yaml run` ### Bug Fixes [dns-proxy] The maximum number of upstream connections is now limited by default which should fix reported issues of cloudflared exhausting CPU usage when faced with connectivity issues.
