-# Version 2.14.5: UNRELEASED
+# Version 2.14.5: Released Nov 4th, 2024
+- Upgraded nanoflann to v1.6.2 (fixes a potential bug).
 - Debian files:
   - Fix appstreamcli warnings in metadata XML files.
+- Changes in libraries:
+  - \ref mrpt_expr_grp
+    - ExprTk updated to latest version (https://www.partow.net/programming/exprtk/exprtk_release_notes_v0.0.3.txt).
 - BUG FIXES:
   - mrpt::maps::CPointsMapXYZIRT::getPointRGB() now handles the case of no intensity without throwing, fixing the visualization of such clouds through mrpt::opengl::CPointCloudColoured::loadFromPointsMap().
   - GridmapNavSimul: Loading a different gridmap won't update the map visualization.
