All notable changes to iNTERCEPT will be documented in this file.
## [2.21.1] - 2026-02-20
### Fixed
- BT Locate map first-load rendering race that could cause blank/late map initialization
- BT Locate mode switch timing so Leaflet invalidation runs after panel visibility settles
- BT Locate trail restore startup latency by batching historical GPS point rendering

## [2.21.0] - 2026-02-20
