2.10.0 (2026-05-19)

2.10.0 lands FIDO2 hardware security keys, the multi-account Manage dialog, and a redesigned full-window screen-share picker, alongside fixes for MCAS auth, SharePoint concurrent downloads, and the ozone x11 default. Most new features are opt-in via config; only the screen-share picker is on by default.

How to enable each new feature

Add the relevant block to your config.json:

:::json
{
  "auth": { "webauthn": { "enabled": true } },
  "multiAccount": { "enabled": true },
  "download": { "enabled": true },
  "notifications": { "timeoutType": "never" }
}

• auth.webauthn.enabled — FIDO2 hardware security keys. Linux only, requires the fido2-tools system package (apt install fido2-tools / dnf install fido2-tools / pacman -S libfido2). Silent no-op on macOS and Windows.
• multiAccount.enabled — multi-account profile manager (Add / Switch / rename / remove). Mutually exclusive with auth.intune.enabled; if both are true, multi-account is auto-disabled with a startup warning.
• download.enabled — master switch for download completion toast and taskbar progress. Once on, sub-flags notifyOnDownloadComplete, showProgressBar, and showTitlePrefix each default true and can be turned off individually.
• notifications.timeoutType: "never" — persistent notifications on Linux and Windows (workaround for GNOME and other desktops that auto-clear). Choices are default or never.

Always-on this release (no config needed): the new screen-share picker overlay, the SharePoint QUIC fix, the MCAS proxy cookie-domain fix, telemetry beacon blocking, and log-noise cleanup.
