-## [v5.3.1](https://github.com/prysmaticlabs/prysm/compare/v5.3.0...v5.3.1) - 2025-03-13
-
-This release is packed with critical fixes for **Electra** and some important fixes for mainnet too. 
-
-The release highlights include:
-
-- Ensure that deleting a block from the database clears its entry in the slot->root db index. This issue was causing some operators to have a bricked database, requiring a full resync. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15011)
-- Updated go to go1.24.0. [[PR]](https://github.com/prysmaticlabs/prysm/pull/14969)
-- Added a feature flag to sync from an arbitrary beacon block root at startup. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15000)
-- Updated default gas limit from 30M to 36M. Override this with `--suggested-gas-limit=` in the validator client. [[PR]](https://github.com/prysmaticlabs/prysm/pull/14858)
-
-Known issues in **Electra**:
-
-- Duplicate attestations are needlessly processed. This is being addressed in [[PR]](https://github.com/prysmaticlabs/prysm/pull/15034).
-
-Testnet operators are strongly encouraged to update to this release. There are many fixes and improvements from the Holesky upgrade incident.
-
-Mainner operators are recommended to update to this release at their regular cadence. 
-

-
-## [v5.3.0](https://github.com/prysmaticlabs/prysm/compare/v5.2.0...v5.3.0) - 2025-02-12
-
-This release includes support for Pectra activation in the [Holesky](https://github.com/eth-clients/holesky) and [Sepolia](https://github.com/eth-clients/sepolia) testnets! The release contains many fixes for Electra that have been found in rigorous testing through devnets in the last few months.
-
-For mainnet, we have a few nice features for you to try:
-
-- [PR #14023](https://github.com/prysmaticlabs/prysm/pull/14023) introduces a new file layout structure for storing blobs. Rather than storing all blob root directories in one parent directory, blob root directories are organized in subdirectories by epoch. This should vastly decrease the blob cache warmup time when Prysm is starting. Try this feature with `--blob-storage-layout=by-epoch`.
-
-Updating to this release is **required** for Holesky and Sepolia operators and it is **recommended** for mainnet users as there are a few bug fixes that apply to deneb logic.
