Loop Client Release Notes

This file tracks release notes for the loop client.

When new features are added to the repo, a short description of the feature should be added under the "Next Release" heading.
This should be done in the same PR as the change so that our release notes stay in sync!

All of the items under the "Next Release" heading should be included in the release notes.
As part of the PR that bumps the client version, cut everything below the 'Next Release' heading.
These notes can either be pasted in a temporary doc, or you can get them from the PR diff once it is merged.
The notes are just a guideline as to the changes that have been made since the last release, they can be updated.
Once the version bump PR is merged and tagged, add the release notes to the tag on GitHub.

Next release

If lnd is locked when the loop client starts up, it will wait for lnd to be unlocked. Previous versions would exit with an error.
Loop will no longer need all lnd subserver macaroons to be present in the --lnd.macaroondir. Instead the new --lnd.macaroonpath option can be pointed to a single macaroon, for example the admin.macaroon or a custom baked one with the exact permissions needed for Loop. If the now deprecated flag/option --lnd.macaroondir is used, it will fall back to use only the admin.macaroon from that directory.
The rules used for autoloop have been relaxed to allow autoloop to dispatch swaps even if there are manually initiated swaps that are not limited to a single channel in progress. This change was made to allow autoloop to coexist with manual swaps.
The SuggestSwaps endpoint has been updated to include reasons that indicate why the Autolooper is not currently dispatching swaps for the set of rules that the client is configured with. See the autoloop documentation for a detailed explanations of these reasons.

The AutoOut, AutoOutBudgetSat and AutoOutBudgetStartSec fields in the LiquidityParameters message used in the experimental autoloop API have been renamed to Autoloop, AutoloopBudgetSat and AutoloopBudgetStartSec.
The autoout flag for enabling automatic dispatch of loop out swaps has been renamed to autoloop so that it can cover loop out and loop in.
The SuggestSwaps rpc call will now fail with a FailedPrecondition grpc error code if no rules are configured for the autolooper. Previously the rpc would return an empty response.
