# Loop Client Release Notes

#### New Features

#### Breaking Changes

* Loop now uses the btcd v2 modules and requires Go 1.26. Projects compiling
  against Loop's exported Go APIs must migrate address, transaction, and
  related types to the corresponding btcd v2 packages.

* Instant Out and reservation RPCs now require the `loop:out` permission.
  Operators using custom scoped macaroons must rebake them before calling
  `ListReservations`, `InstantOut`, `InstantOutQuote`, or `ListInstantOuts`.
  [PR #1194](https://github.com/lightninglabs/loop/pull/1194)

#### Bug Fixes

* Loop Out requests now account for channel reserves when checking outbound
  capacity, preventing swaps from starting when their off-chain payment cannot
  be funded.

* Improved Instant Out and reservation validation, lifecycle cleanup, recovery
  timing, fee limits, and macaroon permissions.
  [PR #1194](https://github.com/lightninglabs/loop/pull/1194)

* Taproot Asset Loop Out handling now validates RFQ timeouts and asset rates,
  keeps cached asset-name lookups responsive during slow `tapd` queries, and
  closes `tapd` connections cleanly during shutdown and startup failures.
  [PR #1189](https://github.com/lightninglabs/loop/pull/1189)

#### Maintenance

* Added a CI gate and repository agent guidance requiring every pull request to
  include a non-empty entry in the next release notes unless it carries the
  `no-changelog` label.
