Comment on Rust CLI with Clapparent

Comments

Seems unfair. Version 4 was almost 3 years ago and and I can't recall any issue in that time.

Major versions have good quality migration guides. If only all libraries were developed with such professionalism.

Yes 4 has been out for a while but I was caught in the time when it went from v2 (2020) to v3 (2021) to v4 (2022). I made the mistake of rewriting all the chapters from using 2 to 3, which was quickly deprecated for 4.
