• Compatibility improvements:
  • Bake in some terminals' definitions into the static binaries, allowing btdu to work even with no terminfo database on the host system
  • Improve locale initialization, improving behavior when the system default locale is broken
• Deletion improvements:
  • Fix segmentation fault when deleting files
  • Update deletion logic with new internal representation, making simulated retroactive deletion precise
  • Discard samples and subvolumes from before deletion operations complete, preventing re-ingestion of stale samples with deleted paths
  • Fix cursor disappearing when deleting marks while a marked item is also selected

Full Changelog: v0.7.1...v0.7.2

• Fix static binaries failing to find terminfo database

Only prebuilt static binaries were affected. Source builds and distribution packages do not require updating.

• New internal in-memory representation, improving performance by up to 35% and memory usage by up to 60%
• Add new compact, lossless binary export format, reducing export size by ~×25 while fully preserving all data
• Add --compare mode for comparing against a baseline export, to help understand disk usage changes over time
• Add --auto-mount flag to automatically mount a non-top-level mount or block device in a temporary namespace
• Add ⇧ ShiftP, ⇧ ShiftI keys to interactively edit path preference rules (--prefer / --ignore)
• Add y key to copy the selected path to the clipboard
• Add Tab ↹ key to toggle the info panels
• Add human-readable output summarizing the disk usage, printed by default in --headless mode
• Add sharing groups counter and Good-Turing coverage estimate to status bar
• Add Chao1 estimate of undiscovered items in directories
• Replace normal approximation with Wilson score interval for calculating object size confidence bounds
• Add disk map visualization
• Add --version
• Add smart abbreviation algorithm for "Shares data with" paths
• Ring the terminal bell when a stop condition is reached in interactive mode
• Interactive export now suggests a default file name based on the filesystem ID (fsid)
• Make --max-samples stop precisely at the requested limit
• Make --max-samples=0 and --max-time=0 do what is expected (pause or stop before ingesting any samples)
• Improve error message printed when given a non-top-level mount with structured guidance
• Use toasts for transient messages
• Scale info panel width on wide terminals
• Remember the selection and scroll position when navigating away and back to a node
• Clarify effects of deleting directories in deletion confirmation pop-up
• Change * behavior to only toggle selection of visible items
• Fix visual UI freeze while deleting
• Switch to Nix for deterministic, reproducible static builds
• Use musl for static builds on all platforms
• Build more dependencies with LTO for improved file size
