-## Release notes
+# Release notes

+- Removed the need for GEMC-specific environment variables in Python example
+  workflows: the API runs through the `pygemc` module, and users only need the
+  executable in `PATH`.
+- Updated the Cherenkov optical example with neutral demonstration radiator names:
+  `lowIndexRadiator`, `mediumIndexRadiator`, and `highIndexRadiator`.
+- Added y-vs-x analyzer plotting support in `pygemc` and used it for the
+  Cherenkov homepage plots.
+- Regenerated the Cherenkov homepage VTK and PNG assets with the updated
+  radiator variations.
+- Updated the Cherenkov example documentation to use a one-electron quick
+  workflow and to note that demonstration optical constants may be unphysical.

 ## Detailed list of changes and fixes
 
 - Better generator statistics for some examples
 - Api and analyzer moved to pygemc module 
 - Examples and tests adapted to use pygemc
 - Fixed typos for various goptions help
 - Fixed meson tests checking <lib> dir
+- Added `gemc-analyzer --plot yvsx` support through the `pygemc` subproject,
+  including configurable x/y limits for position plots.
+- Reworked the Cherenkov example variations to use neutral radiator names
+  instead of real gas names.
+- Replaced the old Cherenkov homepage image names with radiator-based names and
+  updated the plots from one-event runs.
