# 0.15.0

**Released on October 29th, 2025**

Due to CommonJS compatibility, the module type needs to be explicitly declared in certain cases. If you see an error like
`ERROR: Top-level await is currently not supported with the "cjs" output format` and are intended on using ESM then
you should set `"type": "module"` in your package.json.

* Handling inflight transmissions

*Introduced special handling cases for `REQUEST_ALREADY_IN_FLIGHT` and `SUBMISSION_ALREADY_IN_FLIGHT`, now in those cases
the SDK will retrieve the inflight submission and track that for ..AndWait functions.*

* support cjs module

*The SDK now has a cjs release for consumption.*

* better handling of readAs and actAs rights

*Upgraded the handling in regards to readAs and actAs to be more fleshed out, especially also for the listWallets function.*

* ACS client side caching

*Querying the ACS is an expensive ledger API operation, as an alternative the ACS is fetched into memory once and subscribe to new
events instead. This should significantly reduce the load on the ledger especially in heavy read operations.*

* Caching of Access Tokens

*Previously a new token was retrieved from the AuthController every time a request was made, this is not a huge problem for `unsafe` tokens,
however still unnecessary. Tokens are now kept in memory and reused and a new token is only requested upon expiry.*

*For this change to take effect you need to alter your token usage to use `AccessTokenProvider` instead, all examples are updated accordingly.*
