What is new in TreeMap 5.2.0

# TreeMap 5.2.0

**A scan engine of its own, safer deleting, and a map you can read at a glance.**

TreeMap now scans with its own engine, written in Rust, and no longer reads the whole disk a second time after every scan, which was the biggest cause of slow, stuttering whole-disk scans. Opening TreeMap never starts a scan by itself, every route to the Trash is more careful, and sizes now use decimal units, as Finder does. It also fixes several security problems, so please update (see Security below). There is no 5.1.0: this release follows 5.0.1.

## ✨ Highlights

- **A native scan engine, written in Rust.** It asks the system for a whole folder's list in one request and works on several cores at once. On a Mac, on a 200,000-item folder the computer had read recently, it went through 412,291 items a second against the built-in walker's 131,203: about three times as fast. On a 1,000,000-item folder too big for the file cache, the disk sets the pace: 91,308 items a second, about 11% faster than the walker's 82,497 and slower than the gdu helper 5.0.1 used on a Mac. TreeMap picks the engine for you and says which one ran and why.
