| `stage()` is definitely not something you need every day, but it does resolve a range of issues (like the one above) and it is nice to have full transparency and control over the aesthetic evaluation. | ||

| ### More extensible theming |

In this section, I think it would be helpful to also see an example of how code can then make use of the new theme element, just like I did in the examples to register_theme_elements(). Apart from making the example less abstract, it'll also show the use of element_render(). As much as possible, we don't want extension developers to work with the contents of the theme elements directly. We may even want to state that they should use calc_element() to access and element_render() to render the theme elements.

The reason I didn't do this was that I didn't want to drag in the creation of a new coord etc. just for that. I think that's beyond the scope of a release post. If you really think it is necessary I can add it, though

It's fine if you think it's beyond the scope. In this case, maybe refer the reader to the documentation of register_theme_elements() for a complete working example.
| The last ggplot2 release was mainly a performance-oriented release. This one, on the other hand is packed with features, big and small. There is also a slew of bug-fixes, but as that make for less interesting reading, please consult the NEWS.md file for those. Further, we have now removed reshape2 from the dependencies, which further removes the indirect dependencies on plyr, stringi and stringr. We have been shaving off dependencies in ggplot2 over a range of releases, and with the removal of reshape2 we are now close to being as lean as we believe is possible. | ||

| ### Rewrite of axis code | ||
| While Dewey has worked on a lot of different parts of the ggplot2 code base, the lion share has been concerned with a rewrite of the positional guide (axis) internals. While, at a high level, axes and legends are equivalent (they are both guides used for scales), this has not been true for the underlying code. With this release we have streamlined the implementation considerably, and paved the way for a full guide rewrite in a future release (guides are one of the last part waiting to be updated to ggproto). Apart from making our life as ggplot2 developers easier, the rewrite also comes with a slew of user facing improvements and features. All of this is contained in the new `guide_axis()` function that works equivalently to e.g. `guide_legend()`. |

^^ changed lion share to lion's share; added hyphens to compound modifiers (e.g. user facing improvements → user-facing improvements)
Also, might link to the guide_axis() function reference, once the main pkgdown site is a go.

@batpigandme can you give it a quick run-down again as I have updated the post with inputs from you and Hadley |
Release post for ggplot2 3.3.0 slated for feb 24.
