CSS
Bootstrap has been upgraded to last 3 version, v3.4.1.
Theorically, we could upgrade further by looking on startbootstrap repository how our template evolved. There is a v2 of our theme, https://startbootstrap.com/previews/sb-admin-2, that now supports Bootstrap 4.5, but it's not really clean / simple.
JavaScript
JS libraries:
| Library | Current version | Last version | Compatible jQuery version |
|---|---|---|---|
| jQuery | 1.10.2 | 3.7.1 / 2.2.4 / 1.24.4 | - |
| DataTables | 1.10.0-dev | v2.3.4 | 3.7.0 |
| metisMenu | ? | 3.0.7 | 3.4.1 |
Plan would be to check if metisMenu still work with jQuery 3.7 and if so upgrade jQuer and the two libs to last library version.
