1. Remove all "cte" code from Maxima - mostly install.
2. Support for Maxima 5.47.0, 5.48.0, and 5.49.0. This includes a fix for issue #1281 from 5.48.0.
3. Question tests can now test the whole route through a PRT, rather than just the final node. This is a significant improvement on the ability to test questions. This is back-compatible with older questions.
+4. Move chemistry data and some core functions into the Maxima supported code. Load these with `stack_chemistry_declare(true);` in the question variables.

## Using chemical data
@@ -49,7 +47,7 @@ Notes.
1. Names of elements are always given as strings. E.g. to access data for hydrogen use `"H"`.
2. Field names are always given as strings, e.g. `"AtomicMass"` is a string (not an atom `AtomicMass`).
3. The utility functions filter the `"Name"` field to give the name of the element with the local language selection. STACK uses the global `%_STACK_LANG` variable. If no local name is defined the `"Name"` in English is returned. If you really want _all_ the data, just use `assoc(element, %_STACK_CHEM_ELEMENTS)` rather than ` chem_data_all(element)`.
-4. Note that, for efficiency reasons, data is stored in flat table and the above arrays are reconstructed from the flat table, the list of field names and any languages available. Language data is separated which makes it easier to add a new language. Chemical names are _not_ part of Moodle's normal language pack and need to be added explicitly to `chemistry.mac`. See [github](https://github.com/maths/moodle-qtype_stack/blob/master/stack/maxima/contrib/chemistry.mac) for examples. As of Nov 2025, English, Finnish and German names are available.
