 # 0.42.0
 
+## Breaking Changes
+
+**AdvancedVI 0.5**
+
+Turing.jl v0.42 updates `AdvancedVI.jl` compatibility to 0.5.
+Most of the changes introduced in `[email protected]` are structural, with some changes spilling out into the interface.
+The summary of the changes below are the things that affect the end-users of Turing.
+For a more comprehensive list of changes, please refer to the [changelogs](https://github.com/TuringLang/AdvancedVI.jl/blob/main/HISTORY.md) in `AdvancedVI`.
+
+- A new level of interface for defining different variational algorithms have been introduced in `AdvancedVI` v0.5. As a result, the method `Turing.vi` now receives a keyword argument `algorithm`. The object `algorithm <: AdvancedVI.AbstractVariationalAlgorithm` should now contain all the algorithm-specific configurations. Therefore, keyword arguments of `vi` that were algorithm-specific such as `objective`, `operator`, `averager` and so on, have been moved as fields of the relevant `<: AdvancedVI.AbstractVariationalAlgorithm` structs.
+- The default hyperparameters of `DoG`and `DoWG` have been altered.
+- The depricated `[email protected]`-era interface is now removed.

 Due to a technical limitation of MCMCChains.jl, this causes all indexing into MCMCChains to return `Union{Float64, Missing}` or similar.
 If you want the old behaviour, you can discard the first sample (e.g. using `discard_initial=1`).
