Mostly a bug-fix release, but also deprecates more old interface.
**Bug-fixes**
- Fixed a bug when displaying nans in rich displays
**Deprecated**
- `Minuit.minoserror_struct`: use `Minuit.merrors`, which is now an alias for the former
- `Minuit.merrors` now accepts indices and parameter names, like `Minuit.values`, etc.
**Features**
- Show engineering suffixes (1.23k, 123.4M, 0.8G, ...) in rich diplays instead of "scientific format", e.g. 1.23e-3
- New initial step heuristic, replaces pedantic warning about missing step sizes
- New initial value heuristic for parameters with limits
**Documentation**
- New tutorial about using Numba to parallelize and jit-compile cost functions
