What broke in 0.21 w.r.t. 0.20 ?

Hey,

I just wanted to know what changed between the two versions

[lbenet]

The major change in v0.21 is that the Taylor coefficients are internally stored as FixedSizedVectors, which for Julia v1.11 and 1.12 helps in performance. We have solved some minor bugs and improved some internals. Among these, matrix multiplication with Taylor1 or TaylorN matrix elements has be written to be non-allocating (using matmul!), which again helps a lot in performance.

Thanks for the memo, it'll help me check compatibility.
