Select2 dependency in DAL v3.9.5 breaks collectstatic with Whitenoise in production

[mikkonie]

django-autocomplete-light v3.9.5 came out yesterday. It causes collecstatic to fail in production with Whitenoise, at least when using CompressedManifestStaticFilesStorage. I believe this is caused by an update to the select2 dependency within DAL.

This may be midigated by switching to a different storage backend in Whitenoise. Alas, missing files are bad and I don't want to do workarounds just for this broken update.

For now, I'm pinning DAL to v3.9.4. I'll observe how further updates behave.

I've now upgraded the dependency to 3.11.0. In local development all seems fine, but I'll have to see how this behaves with Whitenoise and debug accordingly. If all else fails, I'll revert back to an older version.
