**Full Changelog**: https://github.com/wenottingham/tuatara/compare/v0.4.1...v0.5.0

A few minor bugfixes:
- Fix resize crasher
- Cleanup exit behavior to call out exceptions properly
- Fix some sizing corner cases

**Full Changelog**: https://github.com/wenottingham/tuatara/compare/v0.4.0...v0.4.1

Release 0.4.0 brings the removal of libcaca usage, in favor of [blessed](https://pypi.org/project/blessed/) and python ascii art code.

This brings in:
- truecolor support!
- more cross-platform compatibility (not that it's tested)
- fewer system dependencies

Visualization is restricted to when running in a truecolor terminal (blessed's downsampling for 16/256 color terminals is too slow.)
