Diagnostics that cannot be written are now dropped silently. Also: PDF Editor 0.3.x edits stay editable after a text replacement. Includes 0.3.54 (add-ons ask before restarting the browser) and 0.3.53 (extension updates re-checked every 4 hours, announced by a toolbar chip and installed in place; compact Extensions page; drag-to-reorder toolbar buttons).",
+      "changes": "Sites that offer an app install (a web app manifest) can now be installed from Theseus, the way Chrome and Edge offer it: an install icon in the address bar and in the page menu, the site's own install button works too, and the app gets a Start Menu entry, its own window and taskbar icon while still running inside Theseus with your names, add-ons and settings. Fixes two \"JavaScript error occurred in the main process\" dialogs: one when a wallet connection was dropped while its relay was still connecting, one when the browser window closed while a page was still reporting a hovered link.

The wallet still asks before anything is paired. Also bundles Aegis 0.9.0, which fixes imported Tron, Ethereum and Solana wallets showing a balance but no transaction history or tokens, corrects pending transactions that were displayed as failed, and pairs imported Bitcoin Cash wallets with WizardConnect for the first time.</div>
