Summary: Ledger Live desktop and mobile both jumped to 6.6.0. Focus areas were account sync speed, USB/Bluetooth connection robustness, third-party plugin permission prompts, and security-log export — aimed at cutting down long "syncing blockchain data" stalls and making hardware-connection prompts clearer and traceable.
Main changes:
- Sync speed: request batching and caching strategy tuned for Ethereum and Bitcoin nodes. Internal testing on common home broadband showed first-time sync times down 15%–22%.
- Connection stability: fixed device-disconnect issues some Windows 11 users hit when FIDO and HID drivers contended for the device. A new connection-state self-check button was added.
- Plugin permissions: community plugins now require an explicit authorisation popup; high-risk debug interfaces are disabled by default; the settings page surfaces the last 20 plugin invocations.
- Logs & error codes: diagnostic logs now include timestamps and a device-serial suffix so support can triage faster; common error codes link to self-help guides.
- Visual & usability: account list shows a "Last synced" marker; the send-asset flow falls back to conservative suggestions instead of forcing a submission when gas estimation fails.
Who it applies to: Users who've been sitting on long sync stalls, repeatedly reloading after network changes, or seeing "device already in use" on desktop. Anyone who wants visibility into plugin-call history for security review will also find this useful.
Upgrade steps (desktop):
- Check for updates under Settings → About; once 6.6.0 shows up, download and restart.
- After restart, plug in the device and wait for the "Connected" state; if firmware or app updates are offered, finish firmware first, then apps.
- Open any account and check whether sync time is noticeably shorter. If it's still spinning, try switching nodes under Settings → Accounts & Nodes and retry.
Safety reminder: Ledger Live never asks for your recovery phrase or private keys in a popup. Any prompt asking for the 24 words, or redirecting to a third-party page, should be closed immediately. If the plugin-call list shows an unknown name, disable or uninstall it under Experimental / Plugins and reconnect the device.
Troubleshooting: If "device in use" appears after the upgrade, uninstall old HID devices in Device Manager and replug. Mobile users with flaky Bluetooth can clear the system Bluetooth cache and re-pair. If sync keeps failing, export diagnostics with your network-environment details and submit them to support.
What's next: Ledger has indicated the next point release will focus on session isolation between the hardware wallet and browser extensions, and introduce an optional "read-only mode" for restricted environments. Let 6.6.0 stabilise before enabling experimental plugins.
Safety reminder: We will never ask for your recovery phrase, PIN, verification codes, or private keys. Anyone requesting them is attempting fraud — do not share and do not proceed.
