Hello,
This is to advise you that the Polkadot community is currently preparing to upgrade the systems to the v1.4.3 and v1.5.0 releases.
Breaking change:
These releases will contain a change that adds an additional parameter to the dry-run functionality. As a result, both Runtime code and Frontend clients which are currently accessing the runtime API will default to using the latest version.
We recommend that all ecosystem builders that are calling the DryRunApi upgrade their code to handle the new function.
The projected enactment date for these runtime upgrades will be provided in the Polkadot Technical Fellowship calendar once OpenGov referenda are up for vote.
Many thanks.
