[Pkg-rust-maintainers] Bug#1116060: please upgrade crate imara-diff to v0.2

[Antonin Delpeuch (lists)]

Hi Jonas,

I've had a close look at this and unfortunately it looks complicated. 
The version 0.2 of this crate has been published in a rather unexpected 
way, without any git tag, changelog or migration guide, despite it 
containing a significant range of breaking changes [1]. This seems to 
have reduced the appetite of downstream users to migrate.

The crates that depend on imara-diff and that are currently in sid are 
diffy-imara and gitoxide (gix-diff and gix-merge). None of those 
upstream crates have migrated to imara-diff 0.2 yet; in fact Gitoxide 
has made a deliberate decision not to migrate given the issues above. [2]

Looking at the dependents of this crate on crates.io [3], it seems that 
the vast majority of them is sticking to v0.1 so far.

May I ask which downstream use of this crate is prompting you to request 
this version update? Are you perhaps packaging helix perhaps?

Antonin
