Lightning Node

This update adds support for Backups in umbrelOS 1.5.

This release updates the underlying Lightning Network Daemon (LND) that powers this app to v0.19.2-beta. The update contains important bug fixes and performance improvements for LND.

In addition, the "decayed log database" (sphinxreplay.db) is cleaned up automatically on update, which can reduce disk and memory usage for nodes.

This release updates the underlying Lightning Network Daemon (LND) that powers this app to v0.19.1-beta. The update includes new feature additions, important bug fixes, stability enhancements, and performance improvements for LND. In addition, Testnet4 support has been added.

🚨 There are no breaking changes to the Umbrel app itself; however, if you are a power user who uses automated scripts to interact with your node via the command line, there are breaking changes to the "lncli listchannels" and "lncli closedchannels" outputs that you should consult the release notes for.

🎉 Widgets are here for umbrelOS 1.0.

This update brings three new widgets for the Lightning Node app, allowing you to keep an eye on your node's stats, Bitcoin balance, and Lightning balance right from your Umbrel's home screen:

• Node Stats: A widget that displays the number of peer connections, number of active channels, max send, and max receive for your node.

• Bitcoin Wallet: A widget that shows the balance of your Bitcoin wallet and has shortcuts to send and receive Bitcoin in the Lightning Node app.

• Lightning Wallet: A widget that shows the balance of your Lightning wallet and has shortcuts to send and receive Lightning payments in the Lightning Node app.

After updating to umbrelOS 1.0, you can add widgets by right-clicking on the home screen and selecting "Edit widgets", or by clicking on Widgets in the Dock.

This release updates LND from version 0.17.3-beta to 0.17.4-beta.

This is a hot fix release that fixes multiple bugs: Channel open hanging until restart, a memory leak when using polling mode for bitcoind, sync getting lost for pruned nodes and the REST proxy not working when TLS certificate encryption is turned on.

🔔 In case you missed it, a previous release of the Lightning Node app (v0.17.0-beta) brought the option to run your node in hybrid mode or Tor-only mode, along with the ability to open private channels, receive keysend payments, bugfixes, and more!

• Hybrid mode allows your node to make connections to peers (other nodes) over both Tor and clearnet, enhancing both latency and connection stability. This is enabled by default for new users, while existing users can activate it in Advanced Settings.

• You can now now choose to open private channels, which offer increased privacy but limited routing capabilities compared to public channels.

This release updates LND from version 0.17.2-beta to 0.17.3-beta.

• LND 0.17.3-beta fixes multiple concurrency and memory related bugs. Memory consumption for lnd nodes running with bitcoind using the rpcpolling has been significantly reduced (previously scaled with total mempool size).

This release updates LND from version 0.17.0-beta to 0.17.2-beta.

• LND 0.17.1-beta includes a number of bug fixes and optimizations, including: a reduction in CPU utilization due to the new mempool scanning safety logic, enchantments to the CPFP logic for anchor outputs, a fix to a peer/server deadlock, and a bug fix for the new taproot channel type that may have otherwise caused a channel to show as inactive until reconnection.

• LND 0.17.2-beta includes a fix for a bug that could cause a panic when a channel is closed while a commitment update is being processed.

Introducing Advanced Settings. Take control of your node and customize it to your needs.

• Personalize your node by giving it a name and color.
• Enable larger channels, and limit channel sizes.
• Set your routing fees, and optimize your routing strategy.
• Add watchtower services to guard your channels, and run a service for others.
• Fine-tune the performance and resource usage of your node.
• And much more!

Umbrel patch:

• LND will now connect to Bitcoin Core on other networks e.g. testnet

LND Bug Fixes:

• A Taproot related key tweak issue was fixed in btcd that affected remote signing setups.
• Taproot changes addresses are now used by default for the SendCoins RPC.
• A 1 second interval has been added between FundingLocked receipt checks. This reduces idle CPU usage for pending/dangling funding attempts.
• The wallet birthday is now used properly when creating a watch-only wallet to avoid scanning the whole chain.
• Taproot outputs are now correctly shown as SCRIPT_TYPE_WITNESS_V1_TAPROOT in the output of GetTransactions (lncli listchaintxns).

• Enable RPC middleware in LND

• This is an emergency hot fix release to fix a bug that can cause lnd nodes to be unable to parse certain transactions that have a very large number of witness inputs.

• Bugfix: A bug has been fixed where the responder of a zero-conf channel could forget about the channel after a hard-coded 2016 blocks.
• Bugfix: A bug where LND wouldn't send a ChannelUpdate during a channel open has been fixed.
• Bugfix: A bug has been fixed that caused fee estimation to be incorrect for taproot inputs when using the SendOutputs call.
• Bugfix: A bug has been fixed that could cause lnd to underpay for co-op close transaction when or both of the outputs used a P2TR addresss.
• Taproot: Add p2tr address type to account import.

This update includes LND v0.15.2, an emergency hotfix release to fix a bug that can cause LND nodes to be unable to parse certain large blocks.

This release contains no major features, and is instead just a hotfix applied on top of the last version.

The v0.15 release contains an "on the fly" migration that will start to write items in the revocation log in a more efficient manner. This release (v0.15.1) allows users to reclaim all the old disk space by converting historical records to the new format, with the old records being deleted.

Also new:

• View your total (on-chain + off-chain) balance
• Bitcoin transactions open in local mempool app on your Umbrel (if it's installed)
• Support for Atomic Multi-path Payments (AMP)
