[pgf-tikz] CTAN Upload: pgf

[Manfred Lotz]

Hi The PGF/TikZ Team,
Thanks for the upload. I've installed the new version and updated the
catalog repository.

The changes should become available on the mirrors within the next 24
hours. Then I will post the announcement.

> # BREAKING CHANGES
>  
>  If a topath is bent by any of the in=, out=, bend=, etc. options, a
> Bezier curve is constructed in the background.  To infer the
> positions of the control points the start and end coordinate are
> converted to absolute coordinates. However, this has the effect that
> subsequent points on the path think that the endpoint of the topath
> was absolute which can lead to counter-intuitive path construction,
> e.g. ```latex
>  \draw (2,0) to[out=0,in=180] +(1,0) -- ++(0,-1) -- +(1,0);
>  ```
>  If old code relies on this behavior, this drawing will silently
> break!  Please open an issue if you rely on this.
>  
>  # Bug fixes
>  
>  This release introduces a fix for path handling which concerns
> expansion of tokens on the path in particular with respect to
> conditional.  Previously when the expansion of a conditonal resulted
> in a frozen \relax the parser would just give up.  Now the parser
> will skip over the frozen \relax and continue to expand tokens.
> Whether this will result in a meaningful expansion is up to the user.
>  
>  This release also includes other bug fixes. On GitHub you can click
> the commit hashes and the issue numbers to get to the fix and the
> ticket, respectively.
