Here's a look at the key updates in the latest Prysm release, v6.0.4.
This version continues to build out support for both PeerDAS and Light Clients, crucial areas for the ongoing development of Ethereum's consensus layer.
Several important bug fixes are also included:
- The blob cache size is now correctly set at startup.
- Slashing protection history exports work correctly even when the validator database is in a nested folder.
- A specific API call for state committees now returns the correct error (400) for invalid requests, aligning with the standard.
- Validator builder registrations that were occasionally failing due to eager context cancellation have been fixed.
For users of Prysm's docker images, `/bin/sh` is now symlinked to `/bin/bash`, which can help with script compatibility.
Significant progress on PeerDAS includes implementing the P2P layer and validation pipelines for data column sidecars. Light client support sees additions like mainnet spec tests and support for the req/resp domain.
Finally, for participants on the Hoodi testnet, the default builder gas limit has been raised to 60 million.
## [v6.0.4](https://github.com/prysmaticlabs/prysm/compare/v6.0.3...v6.0.4)
This release has more work on PeerDAS, and light client support. Additionally, we have a few bug fixes:
- Blob cache size now correctly set at startup.
- A fix for slashing protection history exports where the validator database was in a nested folder.
- Corrected behavior of the API call for state committees with an invalid request.
- `/bin/sh` is now symlinked to `/bin/bash` for Prysm docker images.
In the [Hoodi](https://github.com/eth-clients/hoodi) testnet, the default gas limit is raised to 60M gas.
