Lumen 1.5.2 Beta

Lumen 1.5.2 is about speed and polish: smoother scrolling and typing, less battery and memory, plus profiles and a few privacy additions.

Faster

• Smoother scrolling, a faster command bar and start page, and fewer redraws across tabs, toolbar and sidebar
• History is stored in a database, so a visit no longer rewrites the whole history file
• In Low Power Mode, start page backgrounds hold still and background tabs sleep sooner
• When the Mac runs short of memory, background tabs go to sleep automatically
• A page that keeps crashing shows an error instead of reloading forever

New

• Profiles: windows with their own cookies, sign-ins and site data (File › New Window in Profile)
• Pull down at the top of a page to reload it
• Lock any window with Touch ID (File › Lock Window, ⌃⌘L)
• Rename tab groups from the top tab bar too
• Resume failed or cancelled downloads
• Camera and microphone choices remembered per site, editable in Settings › Sites

Privacy and security

• More tracking parameters removed, click-tracking redirects (Google, Facebook, Bing, DuckDuckGo and others) skipped
• More fingerprinting and session-replay trackers blocked, and third-party pings and beacons too
• A warning for addresses written with look-alike letters from other alphabets
• Pop-up windows always show their address
• Updates are checked against their signature and a published SHA-256 before installing

Fixes

• Dragging a tab in the top bar moves the tab, not the window
• Bigger click area for the ✕ on tabs
• Reopened tabs return to their group
