Been a little while since our v0.1 announcement. Now at ~~v0.11.6~~ v0.12.0, with functionality spread over over ten repositories:

 ![MLJ_stack](https://global.discourse-cdn.com/julialang/original/3X/b/f/bfbea22a050bdddff7613478677b347738bc366f.png)

[MLJ](https://alan-turing-institute.github.io/MLJ.jl/stable/) has been under continuous development since November 2018. Worth a try if you have not looked at it for a while.

MLJ is a toolbox written in Julia providing a common interface and meta-algorithms for **selecting** , **tuning** , **evaluating** , **composing** and **comparing** machine learning models written in Julia and other languages. Now with access to over 140 models, including most popular **scikit-learn** models, as well as **deep learning** models via [MLJFlux](https://github.com/alan-turing-institute/MLJFlux.jl), recently released.

MLJ strengths include:

- Flexible, carefully thought out API for **model composition** , including new improved `@pipeline` and `@from_network` syntax

- Extendible **hyper-parameter optimization** interface that plays well with model composition, with multiple **resampling** and (nested) **parallelization** options. Recently added algorithms are:

- Searchable database of **model metadata** for matching models to learning tasks

**Developers** should note that MLJ has extensive documentation for [integrating a new machine learning model](https://alan-turing-institute.github.io/MLJ.jl/stable/quick_start_guide_to_adding_models/) into MLJ and for [adding a hyper-optimization algorithm](https://github.com/alan-turing-institute/MLJTuning.jl#how-do-i-implement-a-new-tuning-strategy).

I appear to have v0.12.0 on my machine. 🙂

Can you quickly zip that and send it to me. Save me a lot of work!! 😆

I’m confused. It looks like v0.12 came before 11.5:

[https://github.com/alan-turing-institute/MLJ.jl/releases/tag/v0.12.0](https://github.com/alan-turing-institute/MLJ.jl/releases/tag/v0.12.0)

Was there a mixup in version naming or is the point of v0.11.6 to continue to make v0.11 bugfix releases while simultaneously moving forward with breaking releases?

Okay egg on my face. I made a post 0.12 fix to 0.11.5 that I had completely forgotten about!!

**Current version is indeed 0.12.0**
