# Manifolds.jl 0.11

We just released a breaking change for Manifolds.jl.  
If you “just used” manifolds, not much has changed, maybe the order of parameters in the manifold types, since we unified that as described [here](https://juliamanifolds.github.io/ManifoldsBase.jl/stable/design/#General-order-of-parameters).

The main breaking change was caused

- on the one hand by the small breaking update in ManifoldsBase.jl
- on the other hand due to removing all Lie groups – called `GroupManifold`s, since these have been refactored the last year to their own package [`LieGroups.jl`](https://discourse.julialang.org/t/ann-liegroups-jl/128294). If you did use group manifold, we wrote a detailed [How to transition](https://juliamanifolds.github.io/LieGroups.jl/stable/tutorials/transition/) tutorial and list of changes.

With this breaking change, the duplication of code and names we had for a while is gone (again) and one can easily use Manifolds.jl and LieGroups.jl in the same project in parallel.
