# Eclair vnext
|

<insert here a high-level description of the release>
|
|
|
|
## Major changes
|
|
|
|
### Update minimal version of Bitcoin Core
|
|
|
|
With this release, eclair requires using Bitcoin Core 27.1.
|
|
Newer versions of Bitcoin Core may be used, but have not been extensively tested.
|
|
|
|
This version introduces a new coin selection algorithm called [CoinGrinder](https://github.com/bitcoin/bitcoin/blob/master/doc/release-notes/release-notes-27.0.md#wallet) that will reduce on-chain transaction costs when feerates are high.
|
|
|
|
To enable CoinGrinder at all fee rates and prevent the automatic consolidation of UTXOs, add the following line to your `bitcoin.conf` file:
|
|
|
|
```conf
|
|
consolidatefeerate=0
|
|
```
|

## Verifying signatures
|
|
|
|
You will need `gpg` and our release signing key 7A73FE77DE2C4027. Note that you can get it:
|
|
|
|
- from our website: https://acinq.co/pgp/drouinf.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 drouinf.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 22.04
|
|
- AdoptOpenJDK 11.0.22
|
|
- Maven 3.9.2
|
|
|
|
Use the following command to generate the eclair-node package:
|
|
|
|
```sh
|
|
mvn 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 11, 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.
