mathlib incompatibility detected
An incompatibility has been detected between this project and recent changes in mathlib.
In other words, this project can't advance to the tip of mathlib without breaking.
First incompatible mathlib commit: 8819c75 — feat: withDensity of compositions of kernels and measures (#41192) (2026-08-25 (Rémy Degenne)).
Last-known-good mathlib commit: aac7f62 — feat(LinearAlgebra/Matrix): add elementary row operations (#38596) (2026-08-25 (Junye))
Verified when LeanMachineLearning/LML was at: c33199e — KL divergence between histories (#236) (2026-09-09 (Rémy Degenne)).
You can reproduce this break by:
- updating
mathlib to 8819c75f772c612aa44445c09aca75b9ce667209
- running
lake update mathlib
- running
lake build
