+# Eclair v0.13.1
+
+This release contains database changes to prepare for the removal of pre-anchor channels.
+Closed channels will be moved to a new table on restart, which may take some time, but will only happen once.
+
+:warning: Note that you will need to run the v0.13.0 release first to migrate your channel data to the latest internal encoding.
+
+This is the last release of eclair where channels that don't use anchor outputs will be supported.
+If you have channels that don't use anchor outputs, you should close them now.
+You can list those channels using the following command:
+
+```sh
+$ eclair-cli channels | jq '.[] | { channelId: .data.commitments.channelParams.channelId, commitmentFormat: .data.commitments.active[].commitmentFormat }' | jq 'select(.["commitmentFormat"] == "legacy")'
+```
+
+If your peer is online, you can then cooperatively close those channels using the following command:
+
+```sh
+$ eclair-cli close --channelId=<channel_id_from_previous_step>  --preferredFeerateSatByte=<feerate_satoshis_per_byte>
+```
+
+If your peer isn't online, you may want to force-close those channels to recover your funds:
+
+```sh
+$ eclair-cli forceclose --channelId=<channel_id_from_previous_step>
+```
+
+:warning: This release also updates the dependency on Bitcoin Core to v29.x (we recommend using v29.2).
+
+## Major changes
+
+### Move closed channels to dedicated database table
+
+We previously kept closed channels in the same database table as active channels, with a flag indicating that it was closed.
+This creates performance issues for nodes with a large history of channels, and creates backwards-compatibility issues when changing the channel data format.
+
+We now store closed channels in a dedicated table, where we only keep relevant information regarding the channel.
+When restarting your node, the channels table will automatically be cleaned up and closed channels will move to the new table.
+This may take some time depending on your channels history, but will only happen once.
+
+### Remove support for legacy channel codecs
+
+We remove the code used to deserialize channel data from versions of eclair prior to v0.13.
+Node operators running a version of `eclair` older than v0.13 must first upgrade to v0.13.0 to migrate their channel data, and then upgrade to the latest version.
+
+### Update minimal version of Bitcoin Core
+
+With this release, eclair requires using Bitcoin Core 29.x.
+Newer versions of Bitcoin Core may be used, but have not been extensively tested.
+
+### New MPP splitting strategy
+
+Eclair can send large payments using multiple low-capacity routes by sending as much as it can through each route (if `randomize-route-selection = false`) or some random fraction (if `randomize-route-selection = true`).
+These splitting strategies are now specified using `mpp.splitting-strategy = "full-capacity"` or `mpp.splitting-strategy = "randomize"`.
+In addition, a new strategy is available: `mpp.splitting-strategy = "max-expected-amount"` will send through each route the amount that maximizes the expected delivered amount (amount sent multiplied by the success probability).
+
+Eclair's path-finding algorithm can be customized by modifying the `eclair.router.path-finding.experiments.*` sections of your `eclair.conf`.
+The new `mpp.splitting-strategy` goes in these sections, or in `eclair.router.path-finding.default` from which they inherit.
+
+### Configuration changes
+
+No notable changes.
+
+### API changes
+
+- the `closedchannels` API now returns human-readable channel data
+
+### Miscellaneous improvements and bug fixes
+
+No notable changes.
+
+## Verifying signatures
+
+You will need `gpg` and our release signing key E04E48E72C205463. Note that you can get it:
+
+- from our website: https://acinq.co/pgp/drouinf2.asc
+- from github user @sstone, a committer on eclair: https://api.github.com/users/sstone/gpg_keys
+
+To import our signing key:
+
+```sh
+$ gpg --import drouinf2.asc
+```
+
+To verify the release file checksums and signatures:
+
+```sh
+$ gpg -d SHA256SUMS.asc > SHA256SUMS.stripped
+$ sha256sum -c SHA256SUMS.stripped
+```
+
+## Building
+
+Eclair builds are deterministic. To reproduce our builds, please use the following environment (*):
+
+- Ubuntu 24.04.1
+- Adoptium OpenJDK 21.0.6
+
+Then use the following command to generate the eclair-node packages:
+
+```sh
+./mvnw clean install -DskipTests
+```
+
+That should generate `eclair-node/target/eclair-node-<version>-XXXXXXX-bin.zip` with sha256 checksums that match the one we provide and sign in `SHA256SUMS.asc`
+
+(*) You may be able to build the exact same artefacts with other operating systems or versions of JDK 21, we have not tried everything.
+
+## Upgrading
+
+This release is fully compatible with previous eclair versions. You don't need to close your channels, just stop eclair, upgrade and restart.
