 # Change Log
 All notable changes to this project will be documented in this file.
 
+## [1.9.0] - 2026-02-27
+
+### Added
+ - Added five new queries in the Microsoft subfolder.  These queries are now part of our recommended and must-run sets.
+     - ConditionallyUninitializedVariableAutomation.ql: Flags calls to initialization functions whose return status is not checked, potentially leaving a local variable uninitialized.
+     - UnprobedDereference.ql: Detects dereferences of user-provided pointers that haven't been probed first, which could cause access violations.
+     - UserModeMemoryOutsideTry.ql: Finds reads of user-mode memory that occur outside a try/catch block, where unexpected exceptions from changed memory protections could crash the kernel.
+     - UserModeMemoryReadMultipleTimes.ql: identifies double-fetch vulnerabilities where user-mode memory is read more than once without being copied to kernel memory first.
+     - UnguardedNullReturnDereference.ql: Reports dereferences of return values from calls that may return NULL (e.g. heap allocations) without a preceding null check.
+
+### Changed
+ - Standardized the rule ID of UninitializedPtrField.ql to "cpp/microsoft/public/likely-bugs/uninitializedptrfield" and updated accuracy.
+
 ## [1.8.3] - 2026-02-25
