-## Unreleased
+## [0.3.1] - 2025-07-14
 
--
+### Added
+
+ - `gl-client` 0.3.1 released, including the signer for CLN
+   v.25.05. Upgrading the client and signer will trigger an upgrade on
+   the server, and you will be using the latest and greatest CLN
+   version going forward. 
+ - Added support to `trampoline_pay`, a payment exection engine that
+   delegates route selection and payment execution to the LSP node.
+ - Several signer policies have been relaxed in order to prevent
+   signer rejections. Some rejections are still happening due to a
+   mismatch in CLN and VLS data models, but most should be fixed.
+ - A standalone `gl-testserver` subproject allows testing non-python clients by spinning up a mock Greenlight system in a box, and then run tests against it. ([#539][PR539])
+ - A python-specific subprohect `gl-testing` allows writing extensive `pytest` tests against Greenlight. If you are using Python, this is a great way to test your project
+ - Added CLN v24.11 as supported version on the server.
+ - Added a rust-based `glcli` command line client replacing the python `glcli`
+
+### Changed
+
+ - `trampoline_pay` performs a preflight check to see if we have enough `spendable_msat` before attempting the trampoline payment. ([#585][PR585])
+
+### Fixed
 
+ - Fixed a logic error relating to zeroconf channels, and forgetting channels that did not confirm for prolonged periods.

 ### Added

 - Add trampoline client to delegate route finding to next node ([#475](https://github.com/Blockstream/greenlight/pull/475), #[489](https://github.com/Blockstream/greenlight/pull/489), #[498](https://github.com/Blockstream/greenlight/pull/498), #[505](https://github.com/Blockstream/greenlight/pull/505), #[511](https://github.com/Blockstream/greenlight/pull/511)).
 - Add basic support for signer-less devices ([#281](https://github.com/Blockstream/greenlight/pull/281)).
 
+[PR539]: https://github.com/Blockstream/greenlight/pull/539
+
 ### Changed
 
 - Ensure that signer doesn't exit on network change ([#524](https://github.com/Blockstream/greenlight/pull/524))
 - Signer reports the node id by itself ([#520](https://github.com/Blockstream/greenlight/pull/520))
 - Upgrade to VLS 0.12 ([#504](https://github.com/Blockstream/greenlight/pull/504)).
 - Add .resources dir to all crates in repo. This is soley to make it possible to publish artefacts ([#501](https://github.com/Blockstream/greenlight/pull/501))
 
+[PR585]: https://github.com/Blockstream/greenlight/pull/585
+
 ### Fixed
 
 - Several small drive-by fixes ([#468](https://github.com/Blockstream/greenlight/pull/468), [#471](https://github.com/Blockstream/greenlight/pull/471), [#508](https://github.com/Blockstream/greenlight/pull/508))
+
+### Removed
+
+- The methods that used to be in `greenlight.proto` that have been
+  superseded with the `node.proto` version have been removed on the
+  server side. The proto file now contains only Greenlight-specific
+  functionality ([#317][pr317].
+
+## [0.2.0]
+
+### Added
+
+ - The Node Domain has been enabled. This means that ever node now has
+   a unique URL at which the node can always be reached, without
+   having to explicitly schedule it first. This allows bypassing of
+   the scheduler, reducing the time required to start and connect to a
+   node.
+
+ - The plugin now wait for the node to complete its startup before
+   forwarding RPC commands.
+ - Calls to `cln.Node/Invoice` now always include all possible
+   `routehints`. Possible in this case refers to channels with peers
+   that are currently in state `CHANNELD_NORMAL`, both disconnected
+   and connected.
+ - The `gl-plugin` will now wait for both the initial gossip sync and
+   the reconnection to the peers to complete, before allowing `pay`
+   through. This cuts down on spurious payment failures due to missing
+   peers or incomplete network view for routing.
+ - The `gl-client` library and the language bindings have keepalive
+   messages enabled, with a timeout of 90 seconds. This ensures that
+   clients and signers that have been silently disconnected, e.g., by
+   suspending the device or losing network connectivity, will notice
+   and reconnect. [#220][pr220]
+
+### Fixed
+
+ - An issue concerning reconnecting to peers, if the signer attaches
+   before the underlying JSON-RPC has become available has been
+   fixed. This issue would cause peers to remain disconnected despite
+   a signer being attached. [#210][pr210] & [#204][pr204]
+
+### Removed
+
+ - The JS bindings where clobbering the error messages due to
+   incorrect context use. Now we return errors as they are emitted.
+ - The scheduler no longer allows creating `regtest` nodes, since they
+   are unusable without a faucet to get coins for it.
+
+ - Temporarily removed the JS bindings. We will the bindings over to
+   uniffi, and the JS bindings were outdated and unused. But they'll
+   be back.
+ - The API has been simplified by removing methods that were both in
+   `greenlight.proto` as well as `node.proto`. The latter is from the
+   autogenerated `cln-grpc` which supercedes the `greenlight.proto`
+   methods.
+
+ - Payment optimizations: we are working on getting the success rate
+   for payments up, and the time to completion down, focusing on
+   success rate first.
