 ## [Unreleased] - Release date yyyy-mm-dd
 
+## [Version 0.6.2] - Release date 2024-03-15
+
+### Added
+- Added output for CMake's implicitly added link libraries and directories.
+
+### Changed
+- OpenMP target now uses a generator expression for Fortran flags instead of replacing flags in
+  Fortran targets created with BLT macros.
+- Remove setting CMP0076 to OLD which left relative paths in `target_sources()` instead of altering
+  them to absolute paths.
+- Header-only libraries headers now show up under their own target in IDE project views instead of
+  under downstream targets. This only works in CMake >= 3.19, otherwise they will not show up at all.
+- Raised version for base CMake version supported by BLT to 3.15 to support ALIAS targets across BLT.
