+## [25.09.1] - 2025-10-15: "Hot Wallet Guardian II"
+
+Several important fixes, please upgrade!
+
+### Added
+
+ - added verification of GPG keys for the bitcoin and litecoin tarballs. ([#8429])
+
+### Changed
+
+ - lightningd: we defer deletion of old htlcs on channel close, to avoid pausing for a long time (we clean them on startup) ([#8563])
+ - gossipd: add gossip_store recovery for filesystems which do not synchronize read and write (e.g. ZFS on Linux), by disabling mmap reads and rewriting the last records. ([#8566])
+ - Dockerfile: improve build time and reduce image size ([#8429])
+
+### Fixed
+
+ - JSON-RPC: `listchainmoves` could contain bogus duplicate entries after 25.09 bookkeeper migration. ([#8574])
+ - bookkeeper: failed reload of rebalances on restart. ([#8562])
+ - fixed compilation on all target architectures; each had their own bugs (poetry, missing packages...). ([#8429])
+ - fixed cargo cross compilation. it was mistakenly using QEMU before. ([#8429])
+ - fixed CPU compatibility bug described in issue 8456 ([#8429])
+ - lightningd: potential crash when we receive a malformed onion complain from our first peer when using sendonion / injectpaymentonion. ([#8597])
+ - db: migration from v25.09 on a reasonable size account database could take almost infinite time. ([#8587])
+ - pyln-testing: restore compatibility with pre-25.09 CLN versions. ([#8539])
+ - build: we now build on MacOS without errors on the latest Command Line Tools (macOS 15 SDK). ([#8599])
+ - build: fix build with -O2 on 32 bit arm (armhf). ([#8599])
