This release named by Sergi Delgado Segura.

### Added

- JSON-RPC: Added 'state_changes' history to listpeers channels ([4126](https://github.com/ElementsProject/lightning/pull/4126))
- JSON-RPC: Added 'opener' and 'closer' to listpeers channels ([4126](https://github.com/ElementsProject/lightning/pull/4126))
- JSON-RPC: `close` now sends notifications for slow closes (if `allow-deprecated-apis`=false) ([4046](https://github.com/ElementsProject/lightning/pull/4046))
- JSON-RPC: `notifications` command to enable notifications. ([4046](https://github.com/ElementsProject/lightning/pull/4046))
- JSON-RPC: `multifundchannel` has a new optional argument, 'commitment_feerate', which can be used to differentiate between the funding feerate and the channel's initial commitment feerate ([4139](https://github.com/ElementsProject/lightning/pull/4139))
- JSON-RPC `fundchannel` now accepts an optional 'close_to' param, a bitcoin address that the channel funding should be sent to on close. Requires `opt_upfront_shutdownscript` ([4132](https://github.com/ElementsProject/lightning/pull/4132))
- Plugins: Channel closure resaon/cause to channel_state_changed notification ([4126](https://github.com/ElementsProject/lightning/pull/4126))
- Plugins: `htlc_accepted` hook can now return custom `failure_onion`. ([4187](https://github.com/ElementsProject/lightning/pull/4187))
- Plugins: hooks can now specify that they must be called 'before' or 'after' other plugins. ([4168](https://github.com/ElementsProject/lightning/pull/4168))
- hsmtool: a new command was added to hsmtool for dumping descriptors of the onchain wallet ([4171](https://github.com/ElementsProject/lightning/pull/4171))
- hsmtool: `hsm_secret` generation from a seed-phrase following BIP39. ([4065](https://github.com/ElementsProject/lightning/pull/4065))
- cli: print notifications and progress bars if commands provide them. ([4046](https://github.com/ElementsProject/lightning/pull/4046))
- pyln-client: pyln.client handles and can send progress notifications. ([4046](https://github.com/ElementsProject/lightning/pull/4046))
- pyln-client: Plugin method and hook requests prevent the plugin developer from accidentally setting the result multiple times, and will raise an exception detailing where the result was first set. ([4094](https://github.com/ElementsProject/lightning/pull/4094))
- pyln-client: Plugins have been integrated with the `logging` module for easier debugging and error reporting. ([4101](https://github.com/ElementsProject/lightning/pull/4101))

### Changed

- * Requires bitcoind v0.20.1 or above * ([4179](https://github.com/ElementsProject/lightning/pull/4179))
- Plugins: `pay` will now try disabled channels as a last resort. ([4093](https://github.com/ElementsProject/lightning/pull/4093))
- Protocol: mutual closing feerate reduced to "slow" to avoid overpaying. ([4113](https://github.com/ElementsProject/lightning/pull/4113))
- In-memory log buffer reduced from 100MB to 10MB ([4087](https://github.com/ElementsProject/lightning/pull/4087))

### Deprecated

Note: You should always set `allow-deprecated-apis=false` to test for changes.

- Plugins: hooks should now be specified using objects, not raw names. ([4168](https://github.com/ElementsProject/lightning/pull/4168))
- cli: scripts should filter out '^# ' or use `-N none`, as commands will start returning notifications soon ([4046](https://github.com/ElementsProject/lightning/pull/4046))

### Removed

- Protocol: Support for receiving full gossip from ancient LND nodes. ([4184](https://github.com/ElementsProject/lightning/pull/4184))
- JSON-RPC: `plugin stop` result with an empty ("") key (deprecated 0.8.1) ([4049](https://github.com/ElementsProject/lightning/pull/4049))
- JSON-RPC: The hook `rpc_command` returning `{"continue": true}` (deprecated 0.8.1) ([4049](https://github.com/ElementsProject/lightning/pull/4049))
- JSON-RPC: The hook `db_write` can no longer return `true` (deprecated in 0.8.1) ([4049](https://github.com/ElementsProject/lightning/pull/4049))

- JSON-RPC: `listconfigs` duplicated "plugin" paths (deprecated 0.8.0) ([4049](https://github.com/ElementsProject/lightning/pull/4049))
- Plugin: Relative plugin paths are not relative to startup (deprecated v0.7.2.1) ([4049](https://github.com/ElementsProject/lightning/pull/4049))

### Fixed

- Network: Fixed a race condition when us and a peer attempt to make channels to each other at nearly the same time. ([4116](https://github.com/ElementsProject/lightning/pull/4116))
- Protocol: fixed retransmission order of multiple new HTLCs (causing channel close with LND) ([4124](https://github.com/ElementsProject/lightning/pull/4124))
- Protocol: `signet` is now compatible with the final bitcoin-core version ([4078](https://github.com/ElementsProject/lightning/pull/4078))
- Crash: assertion fail at restart when source and destination channels of an HTLC are both onchain. ([4122](https://github.com/ElementsProject/lightning/pull/4122))
- We are now able to parse any amount string (XXXmsat, XX.XXXbtc, ..) we create. ([4129](https://github.com/ElementsProject/lightning/pull/4129))

- build: no longer spuriously regenerates generated sources due to differences in `readdir`(3) sort order. ([4053](https://github.com/ElementsProject/lightning/pull/4053))
- db: Fixed a broken migration on postgres DBs that had really old channels. ([4064](https://github.com/ElementsProject/lightning/pull/4064))
