The VLS team is pleased to announce the [Beta release](https://gitlab.com/lightning-signer/validating-lightning-signer/-/releases/v0.9.1) of the validating lightning signer. This is our MVP2 release, designed to be secure against accidental fund loss and malicious nodes. 

We encourage LN application developers to join our [Matrix room](https://matrix.to/#/#vls:matrix.org), submit a [feature request](https://gitlab.com/lightning-signer/validating-lightning-signer/-/issues/new?issuable_template=Feature%20Request), or take VLS for a spin with sample [CLN](https://gitlab.com/lightning-signer/vls-hsmd) or [LDK nodes](https://gitlab.com/lightning-signer/lnrod).

While the VLS beta is secure against the most common ways a malicious node may steal user funds, it does not yet capture all scenarios in which a user might lose funds. We recommend running VLS in testnet or with limited funds in production until we reach our production release milestone and you are comfortable it adequately protects against all scenarios relevant to your use case.

Highlights for developers:

* Works with CLN and LDK
* Encrypted cloud state backup
* Disaster recovery from signer and node failure
* Complete set of layer-2 [validation rules](https://gitlab.com/lightning-signer/validating-lightning-signer/-/blob/main/docs/policy-controls.md)
* Optional validation rules (e.g. velocity, approval)
* A complete set of layer-1 validation rules (on-chain channel state tracking)
* Heartbeat generation
* Allowlist for approved destinations
* UTXO set oracle guarantees safe on-chain state
* [See here](https://gitlab.com/lightning-signer/validating-lightning-signer/-/blob/main/CHANGELOG.md) for a full changelog

* Tuning performance for embedded processors

Planned for later releases:

* Routing
* BOLT-12 Support
