The third major version of simple_sitemap has been seven months in the making. The module has been rewritten from the ground up and now features a more reliable generation process, a significantly more versatile API and many new functionalities.
Major new features
Ability to create any type of sitemap via plugins
The 8.x-3.x release allows not only to customize the URL generation through URL generator plugins as 2.x did, but also creating custom sitemap types that mix and match a sitemap generator along with several URL generators to create any type of sitemap.
This 3-plugin system coupled with the new concept of sitemap variants makes it possible to run several types of sitemaps on a single Drupal instance. Now e.g a Google news sitemap can coexist with your hreflang sitemap.
A sitemap variant can but does not need to be coupled to entity types/bundles. When creating a sitemap generator, one can define where the content source is located and what to do with it upon sitemap generation/deletion.
Ability to create sitemap variants of various sitemap types via UI
In 3.x links form a specific entity bundle can be indexed in a specific sitemap variant with its own URL. This means, that apart from /sitemap.xml, there can be e.g
- /files/sitemap.xml or
All of these can be completely different sitemap types linking to Drupal entities, external resources. or both. They could also be indexing other sitemaps. The name, label and weight of each variant can also be set in the UI.
