Provide up to date information about Solr server compability

Created on 14 May 2025, 23 days ago

I see the compatibility matrix was removed from the project page a couple of months ago, and there doesnt seem to be much of a replacement.

I do think this matrix was particularly helpful, as it helped guide and communicate what the deprecation schedule for Solr support is, to facilitate planning.

I do appreciate the "Supports Solr versions from 3.6 to 9.x" applied to releases themselves, https://www.drupal.org/project/search_api_solr/releases/4.3.10 .

But given that message, how can I answer when 3.6 or 3.x will be unsupported? for example.

Maybe an up to date matrix on the project page isnt the answer, but a docs page linked from project page is the answer.

Further, I do understand Solr module 4.x is the only supported version. I'm on 4.3.10. Its all server support I'm asking about.

Supplemental note, the README is a bit out of date, it says:

Note: Solr 6.x is still supported by search_api_solr but strongly discouraged.
That version has been declared end-of-life by the Apache Solr project and is
thus no longer supported by them.

But it seems all versions from 3 through 9 are now supported [once again] ?

Clarification would help a lot ;)

    I added this to the product page:

    Search API Solr supports any Solr version from 3.6 to 9.x. Solr 7.x to 9.x are directly supported by the module itself, earlier versions from 3.6 to 6.x require enabling the included search_api_solr_legacy sub-module.
    Solr 10.x support will require some work and will be added sooner or later (sponsors are welcome).

    In general, maintaining detailed informations and testing all versions requires a lot of time. But since there're are no major sponsors anymore, it isn't easy to do all these small tasks.

    Thanks @mkalkbrenner, I suppose so long as it stays up to data with the current stable version that makes me happy, and should reduce your workload.

    If a version support was explicitly removed, then adding it to a release's release notes is sufficient.
