Capability comparison
| Need | Sideblog model | Modern approach |
|---|---|---|
| Store short updates | Ordinary posts | Posts or a justified custom post type |
| Group the updates | Selected category | Category, taxonomy or post type archive |
| Display a stream | Widget or theme function | Query Loop block or maintained template |
| Control quantity | Plugin option | Query settings or template configuration |
| Maintenance | Retired plugin dependency | Supported core plus documented custom code |
The migration principle
Preserve the content layer and replace the display layer first. Moving posts into a new type is a larger change and should solve a requirement that categories cannot meet.
Frequently asked questions
Is modern WordPress compatible with the old Sideblog plugin?
Compatibility should not be assumed, and the known removed/unpatched status makes installation inappropriate. Recreate the output with supported features instead.
