LND PR 10962 fixes an issue where the RBF Cooperative Close Flow could accidentally spend overlay assets during fee bumping by making auxiliary channels incompatible with this flow.
LND PR 10897 ensures that low-Bitcoin-value UTXOs representing high-value overlay assets are not skipped during fee rate increases, by recognizing them as auxiliary channel outputs and including them in sweeps.
LND 20.2 beta fixes a DNS fallback panic during peer discovery by validating record types, not assuming SRV. It also patches an HTLC forward interceptor issue.
LND's PR adds invoice request message support for Bolt 12 offers, building on prior groundwork. Full signature verification and offer checking remain for future PRs.

LND #7858 begins implementing Bolt 12 by adding foundational infrastructure, including a new message type, codec package, and TLV structures. This work follows LND's recent release that included Onion messages, which are crucial for Bolt 12.
Gustavo notes that LND 0.21.0 beta includes production support for simple taproot channels and introduces fast initial synchronization for neutrino nodes.
Gustavo says LND 0.21.0 focuses on internal tooling for Onion Messages and begins migrating key-value databases to SQL-based implementations.
Gustavo states that LDK PR 1647 now only uses itself or the recipient as the introduction node for blinded paths due to LND's partial Onion Message support.
LND removes support for creating Tor v2 onion services, which have been obsolete since October 2021, though it retains ability to verify and rebroadcast old peer announcements containing such addresses.
LND added a fast sync mode for Neutrino clients, allowing import of block headers and compact filters from local files or HTTP sources like block-dn.org to cut initial sync from hours to minutes.
LND fixed a bug where nodes would erroneously try to open public simple taproot channels, which fail as the spec lacks announcements. Channels now downgrade to anchor or legacy types unless explicitly requested as private.
LND removes deprecated V1 endpoints for sending payments and single-channel fields, forcing migration to V2 methods.
LDK Server is a new binary daemon from Spiral that simplifies running a Lightning node or LSP, offering features like splicing and Bolt 12 ahead of LND.
Eclair PR #3144 updates simple taproot channels to use the official feature bit, aligning with LND's production implementation from Newsletter #401.
LND adds a 'source_pub_key' field to route construction. This allows calculating routes from another node's perspective, not just your own.
