4.8

• Fixed a fatal error that could happen when activating two plugins or themes that use Composer autoloaders and include different versions of this library. Projects that don't use a Composer-generated autoloader were not affected.
• Fixed a compatibility warning being shown in the "View details" pop-up when the "tested up to" version was specified as major.minor (e.g. 5.2) and the site was running version major.minor.patch (e.g. 5.2.1). This complements an earlier patch where a similar warning was show on the "Updates" page.
• Fixed a potential bug where downloading a release asset from GitHub could fail if multiple plugins enabled release asset support at the same time.
• Added support for GitLab subgroups in self-hosted repositories. Props to @etlam.
• Added Catalan and Spanish translations. Props to @jorditarrida.
• Updated Japanese translation. Props to @GoodMorningCall.
