 * Spin up the STACK API in Docker and check it still works with a selection of questions, including download and JSXGraph.
 * Chances are it won't work because even the latest version of goemaxima is out of date.
 * You will need to create a local up-to-date image of goemaxima:
-  * Clone the goemaxima repo and create a folder stack/STACKVERSION e.g. `stack/2025072400` matching the latest STACK version.
+  * Clone the goemaxima repo and create a folder stack/STACKVERSION e.g. `stack/2024072400` matching the latest STACK version.
   * Copy the stack/maxima folder from STACK into this new folder.
   * Create `maximalocal.mac.template` as described in `Adding_new_version.md` in goemaxima docs (or just copy from previous goemaxima version).
   * In `buildimage.sh` set `maximaver` and `sbclver` e.g. `maximaver="5.45.1" sbclver="2.2.6"`. (`maximaver` should match `maximalocal.mac.template`)
