-## Unreleased
+## [2.5.0.0.4]
 
 ### Added
 
-- Added support for Clarity 3, with new keywords, `tenure-height` and `stacks-block-height`, and removal of `block-height`
+- Adds the solo stacking scenarios to the stateful property-based testing strategy for PoX-4 (#4725)
+- Add signer-key to synthetic stack-aggregation-increase event (#4728)
+- Implement the assumed total commit with carry-over (ATC-C) strategy for denying opportunistic Bitcoin miners from mining Stacks at a discount (#4733)
+- Adding support for stacks-block-height and tenure-height in Clarity 3 (#4745)
+- Preserve PeerNetwork struct when transitioning to 3.0 (#4767)
+- Implement singer monitor server error (#4773)
+- Pull current stacks signer out into v1 implementation and create placeholder v0 mod (#4778)
+- Create new block signature message type for v0 signer (#4787)
+- Isolate the rusqlite dependency in stacks-common and clarity behind a cargo feature (#4791)
+- Add next_initiative_delay config option to control how frequently the miner checks if a new burnchain block has been processed (#4795)
+- Various performance improvements and cleanup
 
 ### Changed
 
 - Downgraded log messages about transactions from warning to info (#4697)
+- Fix race condition between the signer binary and the /v2/pox endpoint (#4738)
+- Make node config mock_miner item hot-swappable (#4743)
+- Mandates that a burnchain block header be resolved by a BurnchainHeaderReader, which will resolve a block height to at most one burnchain header (#4748)
+- Optional config option to resolve DNS of bootstrap nodes (#4749)
+- Limit inventory syncs with new peers (#4750)
+- Update /v2/fees/transfer to report the median transaction fee estimate for a STX-transfer of 180 bytes (#4754)
+- Reduce connection spamming in stackerdb (#4759)
+- Remove deprecated signer cli commands (#4772)
+- Extra pair of signer slots got introduced at the epoch 2.5 boundary (#4845, #4868, #4891)
+- Never consider Stacks chain tips that are not on the canonical burn chain #4886 (#4893)
