CHIBA, Oct 14, 2026 — Frothly today released Glossia 4.0, the latest version of its open, end-to-end encrypted messaging protocol. The release introduces hybrid post-quantum key exchange, which combines established cryptography with newer algorithms designed to resist attack by future quantum computers.
Glossia 4.0 also delivers messages up to 40 percent faster on slow and intermittent connections, and further reduces the information the protocol exposes about who is talking to whom. Existing conversations upgrade automatically, with no action needed from users.
The release follows Glossia’s fourth independent security audit, which found no critical vulnerabilities. Three moderate issues identified during the audit were fixed before release. The full audit report has been published alongside the updated specification.
Glossia is used by an estimated 2.3 million people each month, many of them reporters, organizers and families in countries where private communication carries real risk. The protocol turns fifteen this year.
“The people who rely on Glossia need it to keep working for decades, not just for the next few years. Preparing for quantum computers now is how we keep that promise.”
