# Release Notes

## RPC Server

[Return payment address and add index from
addholdinvoice call](https://github.com/lightningnetwork/lnd/pull/5533).

# Build System

* [A new pre-submit check has been
  added](https://github.com/lightningnetwork/lnd/pull/5520) to ensure that all
  PRs ([aside from merge
  commits](https://github.com/lightningnetwork/lnd/pull/5543)) add an entry in
  the release notes folder that at leasts links to PR being added.

* [A new build target itest-race](https://github.com/lightningnetwork/lnd/pull/5542) 
  to help uncover undetected data races with our itests.

# Documentation

* [Outdated warning about unsupported pruning was replaced with clarification that LND **does**
  support pruning](https://github.com/lightningnetwork/lnd/pull/5553)

# Misc

* The direct use of certain syscalls in packages such as `bbolt` or `lnd`'s own
  `healthcheck` package made it impossible to import `lnd` code as a library
  into projects that are compiled to WASM binaries. [That problem was fixed by
  guarding those syscalls with build tags](https://github.com/lightningnetwork/lnd/pull/5526).

# Code Health

## Code cleanup, refactor, typo fixes

* [Unused error check 
  removed](https://github.com/lightningnetwork/lnd/pull/5537).
* [Shorten Pull Request check list by referring to the CI checks that are 
  in place](https://github.com/lightningnetwork/lnd/pull/5545).
* [Added minor fixes to contribution guidelines](https://github.com/lightningnetwork/lnd/pull/5503).
* [Fixed typo in `dest_custom_records` description comment](https://github.com/lightningnetwork/lnd/pull/5541).

## Database

* [Ensure single writer for legacy
  code](https://github.com/lightningnetwork/lnd/pull/5547) when using etcd
  backend.

[Optimized payment sequence generation](https://github.com/lightningnetwork/lnd/pull/5514/)
to make LNDs payment throughput (and latency) with better when using etcd.
