Lean 1.0.1

Changed

• Background tabs sleep after 5 minutes by default instead of 30; Settings › Tabs › Sleeping tabs still offers 15, 30 and 60
• Opening or restoring a window makes a page only for the tab in front, and every other tab loads when you first show it
• At most one inactive tab keeps a loaded page, so memory stays flat as tabs pile up

Fixed

• Tabs sleep on memory pressure even with automatic sleeping off, and caches are cleared when pressure is critical
• Reopening a closed window restores its session again
• Closed windows, split tabs and the loading bar no longer keep their pages and handlers alive
