v1.5.2 - Composer Sidebar Plugins, Calendar & Contacts Sharing, and Czech Support

on GitHub

1.5.2 (2026-04-27)

Features

• Plugins: New composer-sidebar slot and ui:composer-sidebar permission — plugins can now render a panel on either side of the New Message dialog. See repos/subway-surfers for an example
• Plugins: Manifests can declare frameOrigins — a strictly-validated list of https://host origins the plugin needs to embed. The proxy reads the union from enabled plugins and merges it into the host CSP frame-src, so the host CSP no longer needs to know about specific embed providers
• Calendar/Contacts: JMAP sharing for calendars and address books
• i18n: Czech language support

Fixes

• Security: Validate URLs before outbound fetch
• Calendar: Prevent drag creation on touch events in the time grid
• Contacts: Emit RFC 9553 name kinds and decode QUOTED-PRINTABLE in vCard import (#224, #187)
• Mail: Hide preview line in compact density to match settings preview (#223)
• Proxy: Inline matcher for Next.js proxy and drop unnecessary Node.js runtime config
• i18n: Portuguese fixes for "ficheiro" and "contactos" variants
