[pgf-tikz] CTAN Upload: pgf

Tue Sep 29 11:45:50 CEST 2020

Hello Henri,

we at CTAN have received objections from the bbox library author about the 
section “Removed features” in the announcement, therefore I will remove 
it.

Of course I don't know who did or seems to have done what wrong and when –
but, please, keep CTAN out of your disagreement. 

As far as I can judge, you do not need permissions to publish GPL or LPPL 
licensed software as long as the license terms are met. But understandably 
there are circumstances in which this is considered rude.

To avoid further disputes involving other people, I suggest that you fork 
the affected code under the usual conditions and then release it as the 
maintainer of this fork.

Best
Erik

for the CTAN team

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.

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.

I further recommend that if there are files containing `bbox` code left over from a previous version that these are removed to avoid potential legal issues.
