## Roadmap
- [ ] JMAP for Calendars, Contacts and File Storage support
- [ ] Webmail client
Stalwart has reached an exciting point in its journey, it’s now **feature complete**. All the core functionality and open standard email and collaboration protocols that we set out to support are in place. In other words, Stalwart already does everything you’d expect from a modern, standards-compliant mail and collaboration platform.
See the [enhancement requests](https://github.com/stalwartlabs/stalwart/issues?q=is%3Aissue+is%3Aopen+sort%3Areactions-%2B1-desc+label%3Aenhancement) page for a full list of proposed features by the community.
The next major milestone is all about refinement: finalizing the database schema and focusing on performance optimizations to ensure everything runs as efficiently and reliably as possible. Once that’s done, we’ll be ready to roll out version **1.0**.
Of course, development doesn’t stop there. The community has contributed hundreds of great ideas for improvements and new features, everything from subtle usability tweaks to entirely new integrations. You can see the full list of proposals over on our [GitHub issues](https://github.com/stalwartlabs/stalwart/issues?q=is%3Aissue+is%3Aopen+sort%3Areactions-%2B1-desc+label%3Aenhancement). If there’s something you’d like to see prioritized, just give it a thumbs up as we plan to implement enhancements based on the community’s votes.
