# Acknowledgements

This release stands in the name of the two contributors **Alexander 
Grahn** and **Yukai Chou** without whom this release would not have been 
nearly as great.  Thank you very much!

# BREAKING CHANGES

- In the last version,  in an attempt to fix updating `local bounding box` 
in a clipping scope the `\pgf at path@size at hook` in
`\pgf at protocolsizes` was set to be executed unconditionally.  
Unfortunately, this broke all other uses of `local bounding box` and has 
been
reverted.  If you need to use `local bounding box` in a clipping scope, 
use the `overlay` option.

- The recent Ghostscript version 9.53 has changed the primitives for 
transparency, blend mode, and transparency groups.  These are now
supported by PGF and should in principle go unnoticed by the user. (Thanks 
Alexander Grahn!)

- `\pgfintersectionoflines` will now always return the intersection in the 
untransformed coordinate system.  This however requires an
additional `\pgftransforminvert` which comes with a loss of precision and 
can potentially lead to `Dimension too large` errors in edge cases.

- PGF now supports the new hook management that will be introduced in 
LaTeX 2020/10/01.  While this should not lead to any noticeable
changes, please look out for breakages with overlays and the `current 
page` nodes.  Please report problems on the PGF or LaTeX issue
trackers.

# New features

You can read about these new features in the manual:

- PS-3 functional shading, opacity masks (fadings) and image masks for 
dvips. (Thanks Alexander Grahn!)

- The `dvisvgm4ht` driver developed by Michal Hoftich has been merged into 
PGF/TikZ.

- The `pgfparser` module has been slightly refactored such that it can be 
used without loading all of PGF.

- The order in which the inner styles are applied in a `\matrix` is now 
configurable. #867

- The file `pgfmanual-en-macros.tex` is developed specifically for 
typesetting the PGF manual, however, many other package developers have
found it useful and made good use of it.  To this end, we now install 
`pgfmanual-en-macros.tex` into a directory that is searched by kpathsea
such that developers no longer have to copy the file into their own 
distribution.

- The CI system was switched from Travis CI to GitHub Actions for better 
integration with GitHub and direct deployment of build artefacts to the 
status page.
