+- fix(core): Disable release creation and source maps upload in dev mode (#666)
+
+  This fix disables any external calls to the Sentry API for managing releases or uploading source maps, when detecting that the plugin is running in dev-mode. While this rarely actually happened,
+  it also polluted the dev server output with unnecessary logs about missing auth tokens, which shouldn't
+  be required in dev mode.
