-- Implemented a new `EmptyExecutionPayloadHeader` function.
-- `Finished building block`: Display error only if not nil.
-- Added support to update target and max blob count to different values per hard fork config.
-- Log before blob filesystem cache warm-up.
-- New design for the attestation pool. [PR](https://github.com/prysmaticlabs/prysm/pull/14324)
-- Add field param placeholder for Electra blob target and max to pass spec tests.
-- Add EIP-7691: Blob throughput increase.

-- Limit consolidating by validator's effective balance.
-- Use 16-bit random value for proposer and sync committee selection filter.
-- Re-organize the content of the `*.proto` files (No functional change).
-- Updated spec definitions for `process_slashings` in godocs. Simplified `ProcessSlashings` API.
-- Updated spec definition electra `process_registry_updates`.
-- Updated Electra spec definition for `process_epoch`.
-- Update our `go-libp2p-pubsub` dependency.
-- Re-organize the content of files to ease the creation of a new fork boilerplate.
-- Fixed Metadata errors for peers connected via QUIC.

 ## Maintaining CHANGELOG.md
 
-This project follows the changelog guidelines from [keepachangelog.com](https://keepachangelog.com/en/1.1.0/).
-
-All PRs with user facing changes should have an entry in the CHANGELOG.md file and the change should be categorized in the appropriate category within the "Unreleased" section. The categories are:
-
--  `Added` for new features.
--  `Changed` for changes in existing functionality.
--  `Deprecated` for soon-to-be removed features.
--  `Removed` for now removed features.
--  `Fixed` for any bug fixes.
--  `Security` in case of vulnerabilities. Please see the [Security Policy](SECURITY.md) for responsible disclosure before adding a change with this category.
+This project follows the changelog guidelines from [keepachangelog.com](https://keepachangelog.com/en/1.1.0/). In order to minimize conflicts and workflow headaches, we chose to implement a changelog management
+strategy that uses changelog "fragment" files, managed by our changelog management tool called `unclog`. Each PR must include a new changelog fragment file in the `changelog` directory, as specified by unclog's
+[README.md](https://github.com/OffchainLabs/unclog?tab=readme-ov-file#what-is-a-changelog-fragment). As the `unclog` README suggests in the [Best Practices](https://github.com/OffchainLabs/unclog?tab=readme-ov-file#best-practices) section, 
+the standard naming convention for your PR's fragment file, to avoid conflicting with another fragment file, is `changelog/<github user name>_<PR branch name>.md`.
