```
[TS-Bindings] Ws multiplexing for stream queries is disabled by default as we investigate issues
of intermittent websocket closures.

* There is now an Early Access Helm chart to start all of the Connect components on a Kubernetes cluster.

[JSON-API] Make certain Hikari cp connection pool properties configurable via jdbc conf string, the properties are listed below
poolSize -- specifies the max pool size for the database connection pool
minIdle -- specifies the min idle connections for database connection pool
connectionTimeout -- long value, specifies the connection timeout for database connection pool
idleTimeout -- long value, specifies the idle timeout for the database connection pool
- [Integration Kit] - ledger-api-bench-tool can run a workflow consisting of the command submission phase and stream benchmark phase.
- [JSON API] While updating the contract table for a query, if the DB appears to be slow,
  JSON API will slow down its own inserts and deletes at some point rather than construct
  ever-larger INSERT and DELETE batch commands.
  See `issue #11589 <https://github.com/digital-asset/daml/pull/11589>`__.
[Ledger API] Retry the interpretation of a command in case of a race
with other transactions. This fix drastically reduces the likelihood of the error
"Could not find a suitable ledger time after 0 retries".
[ledger-api] - Return max_deduplication_duration as part of the metadata sent with the gRPC status for commands rejected because of invalid deduplication periods

- [Integration Kit] - ledger-api-bench-tool - added flexible party and template filters for transactions, transaction trees and active contract streams
```
