-## [1.5.1] - 2026-03-25
-
-### Added
-
-- Added `updatehome` and `updatewarp` so existing homes and warps can be moved to the current location without recreating them.
-- Added pagination support and page-picker navigation for `homes` and `warps`, with improved interactive list display for large result sets.
-
-### Changed
-
-- Refactored shared command execution, suggestion, pagination, and chat UI helpers to reduce duplication across `home`, `warp`, and related command flows.
-- Refactored config handling by splitting `ConfigManager` responsibilities and updated command registration to the newer direct-registration path.
-- Improved internal storage concurrency with synchronized asynchronous file I/O, asynchronous config writes, and safer shared-state handling.
-
-### Fixed
-
-- Fixed a shutdown cleanup issue that could terminate background threads unexpectedly while the server was closing.
-- Fixed translation lookup fallback so missing keys now fall back to `en_us` immediately.
-- Fixed teleport-related state cleanup and unsafe-block checking to improve reliability during teleport processing and shutdown.
