# Plots.jl NEWS

#### notes on release changes, ongoing development, and future planned work

- I (@tbreloff) am in development of totally revamped internals, in which much of the logic in building series is changed to recursively stacking recipes in a modular fashion.  I'll write a blog post sometime soon detailing why this is amazing, but for now you can get a taste of it by looking at the [RecipesBase readme](https://github.com/JuliaPlots/RecipesBase.jl)
- Version 0.6.2 will be the last full release of the "Old Plots", and the 0.6 minor will be only small bug fixes.
- All new development should target 0.7 (recipes and subplots)!

## 0.7 (WIP on tb_recipes/dev and master)

- Revamped and simplified internals
- [Recipes, recipes, recipes](https://github.com/JuliaPlots/RecipesBase.jl/issues/6)
- [Layouts and Subplots](https://github.com/tbreloff/Plots.jl/issues/60)
