+- `katex` has been updated from 0.16 to 0.18 and has introduced breaking changes.  See upstream changelog for details: [0.17.0](https://github.com/KaTeX/KaTeX/releases/tag/v0.17.0), [0.18.0](https://github.com/KaTeX/KaTeX/releases/tag/v0.18.0).

 - `keycloak` was updated to >= 26.7.0 and includes some breaking internal (API) changes. See the [upstream migration guide](https://www.keycloak.org/docs/latest/upgrading/#migrating-to-26-7-0) for more information.
 
 - `pdfium` is now built from source instead of packaging prebuilt binaries. `pdfium-binaries` has been renamed to `pdfium`, and `pdfium-binaries-v8` has been removed.
