💥 Breaking changes

• Remove --mutex network argument for Yarn builds (#625) @scherler

If you previously relied on the --mutex network argument (for example, to ensure that only one instance of Yarn runs at any given time when running multiple instances of Yarn as the same user on the same server when running Yarn 1.x), you must now opt in to this behavior explicitly by adding <frontend.yarn.arguments>--mutex network</frontend.yarn.arguments> to the <properties> section of your plugin POM.

• Remove direct dependency on JCIP annotations (#633) @basil

The direct dependency on JCIP annotations has been removed from the plugin POM. Plugins that use JCIP annotations should ensure they have a core baseline of 2.326 or later.

• SpotBugs changes

Updates to SpotBugs may introduce new warnings, such as NP_GUARANTEED_DEREF or NP_NULL_ON_SOME_PATH, due to modified analysis.
