+## Notice: Not under active development {#support-notice}

+**The Polymer library is no longer under active development.** Only very select changes are being made to the code at this point, and newly-reported bugs are unlikely to be fixed unless they represent critical security issues.
+
+**Polymer has been superseded by <a href="https://lit.dev">Lit</a>, a smaller, faster, next-generation web components library.**  Thanks to the interoperability of web components, elements built with Polymer 3.0 and Lit  can be mixed and matched in the same application. You can upgrade a Polymer project to Lit one element at a time.

+*   For information on upgrading, see <a href="https://lit.dev/articles/lit-for-polymer-users/">Lit for Polymer users</a>.
