 # Nylas Java SDK Changelog
 
+## [Unreleased]
+
+### Changed
+* Standardized event status handling on `maybe`
+  - Added `EventStatus.MAYBE` as the primary SDK value for this status
+  - Deprecated `EventStatus.TENTATIVE` as a legacy alias and serialize it as `maybe`
+  - Normalize both API values `maybe` and `tentative` to `EventStatus.MAYBE`
+  - Fall back to `null` for unknown event status values instead of failing deserialization
+
+### Fixed
+* Added request-body support to booking cancellation via `Bookings.destroy()` and `NylasClient.executeDelete()`, allowing `cancellation_reason` to be sent while keeping the legacy no-body booking destroy overload unchanged
+
