I promise I am working on re-enabling outside access to LND and CLN (opt-in) for docker deployments. Meanwhile, this release is packed with security hardening. Update recommended! Boring releases will continue for a little while as we adapt our worfklows to AI...

We’ve updated Core Lightning (CLN) to v26.06.7 in BTCPay Server’s Docker deployment. External access to CLN remains disabled out of an abundance of caution. We expect to safely re-enable it within the next week or two. To update, go to Server Settings → Maintenance → Update, or run btcpay-update(.)sh from the command line after removing the parentheses. Note: ARM32 devices, including some older Raspberry Pis, may not work because ARM32 binaries were not distributed with this CLN release.
Following public reports, we have disabled routes to CLN and Eclair in our default deployment. To update, go to Server Settings → Maintenance → Update, or run btcpay-update(.)sh from the command line after removing the parentheses.

Flint is now live in the BTCPay plugin store and available to all, with a one-click install! Accept Lightning in seconds, no channels necessary. plugin-builder.btcpayserver.… A huge thank you to the @BtcpayServer team for thorough reviews throughout the listing process 🧡
Really excited (and nervous!) to reveal one of the many things I've been working on lately. Without further ado, meet Flint, a new Lightning-enabled @btcpayserver plugin built on the @breez_tech SDK! Note: still early, please test with caution.

Meet Flint ✨

With the @Boltzhq shutdown, Cake Pay lost Lightning capabilities briefly and were stuck looking for another solution for our @BtcpayServer instance but I wasn't happy with any other available

BTCPay Server has disabled routes to Core Lightning and Eclair in its default deployment following the CLN vulnerability reports. If you're running a BTCPay Server instance, update immediately via Server Settings or command line. The AI-generated CVE wave hitting Lightning implementations is already forcing downstream infrastructure to respond in real time.

Appreciate @murchandamus for confirming with CLN maintainers
Looks like a severe Core Lightning (CLN) issue was discovered. It sounds like you should consider restarting your CLN node with `--offline` and be on the lookout for the point release coming in the next few days. (Messages from CLN discord via stacker.news/items/1555439).

Follow @Core_LN & @Snyke for updates
If you run Core Lightning: when the release is published: upgrade with signed binaries, or start your node with `--offline`. Details stay under embargo for two weeks. Previous releases, including 26.04, are unsupported. Full details when the embargo lifts. The 26.09 release is still planned for late September.

BTCPay Server v2.4.3 is now available! Following the release candidates published from our temporary private security repository, today we are releasing the final, fully open-source version of v2.4.3. This is another security-focused update, and we strongly recommend upgrading as soon as possible. As with v2.4.2, external access to the LND API remains restricted. This means remote integrations such as Zeus may not work with BTCPay-hosted LND nodes for now. A huge thank you to every contributor, security researcher and community member who helped review, test, and strengthen this release. The past few weeks have been intense, and this release would not have been possible without you. If you are running one of the previous release candidates, updating will automatically switch your installation to the open-source release. To update, go to Server Settings → Maintenance → Update, or run btcpay-update(.)sh from the command line after removing the parentheses.

We’re working on a safe way to restore compatibility with external apps such as Zeus in the next release. Until then, even if you’re an advanced user running your own fork, we strongly advise against exposing the LND API to the internet.

The next few releases will also be boring... but I think you understand that it is better to be boring that to go through what we've been through.
