How do I fetch versions of a module compatible with latest core version?

Question

I've been using the endpoint https://updates.drupal.org/release-history/[module]/[version], where [module] is the module name and [version] is its version (as 8.x or 7.x). This endpoint, however, doesn't work for 9.x.

For example https://updates.drupal.org/release-history/search_api_solr/8.x works fine but https://updates.drupal.org/release-history/search_api_solr/9.x has nothing, although the module has releases compatible with Drupal 9.

Also, the endpoint for 8.x doesn't return new releases in SEMVER format.

How can I get module releases for Drupal 9? Why aren't SEMVER releases included?

Answer 1

You can use https://updates.drupal.org/release-history/search_api_solr/current to get the versions either prefixed with 8.x- or without an API compatibility prefix. (The latter is the case for SEMVER versions.)

The output from that URL contains information about this release, for example.

<release>
<name>search_api_solr 4.1.1</name>
<version>4.1.1</version>
<tag>4.1.1</tag>
<status>published</status>
<release_link>https://www.drupal.org/project/search_api_solr/releases/4.1.1</release_link>

</release>

It also contains data for this release. (This shows that the URL doesn't return information only for SEMVER versions.)

<release>
<name>search_api_solr 8.x-3.9</name>
<version>8.x-3.9</version>

Unfortunately, there isn't a way to get all the versions that are compatible also with Drupal 9 and not just with Drupal 8, using an updates.drupal.org URL. For that, you need to parse the XML output and filter those versions containing ^9 in the <core_compatibility> tag.

As side note, the all, 8.x, 7.x end-points are considered legacy. I guess that means they could be removed in the future.
