3.1.5b

Hotfix for the external library.

The fix for #759 broke existing uses and has been reverted.

3.1.5a

Hotfix for tikz-3dplot compatibility

The release includes a bugfix for #809

3.1.5

BREAKING CHANGES

• The computation of path times in the intersection library was wrong when sorting intersections and did therefore not work correctly (#480). This is fixed now, but that also means that the order of intersections might change if you were using sorting before. You can easily check this by looking for \pgfintersectionsortbyfirstpath and \pgfintersectionsortbyfirstpath or the sort by key if you are using intersections in TikZ.

• It turned out that in \pgf@protocolsizes the \pgf@path@size@hook was executed only if the picture was actually to be placed. This led to the problem that the local bounding box was not updated correctly (#795). To correct this, the hook is now executed unconditionally.

• To get name prefixes for pic working (#311) the resolution of node names in \tikz@calc@anchor now has two stages. First it tries to look up the prefixed name and uses it if it exists. If there is no prefixed name, the global name without prefix will be looked up and used (fixes #717). Previously, if the prefixed name did not exist and error was issued immediately without attempting to look up the global name.

• There was a bug in old PGF versions that the body of \pgfkeysedef was not fully expanded #305. This was fixed in PGF 3.1 (ac33f7e) by the use of \scantokens. Unfortunately when expanding the body the catcodes at the point of use are taken instead of the catcodes at the point of definition. This led to new bugs like #669. With the new version we are taking a middle ground. We support macro definitions within edef bodies by doubling all the hashes followed by numbers. All other hashes have to be escaped manually. We assume that this is not a common use case.

New features

You can read about these new features in the manual:

• The patterns.meta library now provides a couple of predefined patterns which can be used as replacements for the ones provided by the patterns library.

• Tight bounding boxes for Bezier curves using the bbox library. This feature was contributed by @tallmarmot. Thanks!

• New pgfkeys handler .evaluated

• The RGB color model is now supported in Plain TeX, i.e. values can be integers 0-255 instead of floats 0-1 for rgb.

• Annotations for code examples in the manual as to which libraries are required. These were contributed by Stefan Pinnow (@Mo-Gul). Thanks!

• GitHub issue templates for more streamlined bug reporting.

• New build system based on Lua. We'd like to have a more cross-platform build system. The old system was based on Makefiles, which will be retained for a while but gradually phased out. In the future we hope to be able to implement a regression test suite.

Removed features

• In the last release the undocumented commands \rawx, \rawy, \rawz, and \coord were added to the \path let operation. These proved to be not as useful as anticipated (#731) and were therefore removed again.

3.1.4b

This is a bugfix release for the dvips driver. A regression was introduced in the dvips driver in the last release that led to displaced objects #722. This update fixes the regression but also reverts the fix for position tracking #690.

3.1.4a

This is a bugfix release to make the XeTeX driver less broken. A regression was introduced in the XeTeX driver in the last release that lead to displaced objects #708 #709. This update fixes the regression but also reverts the fix for position tracking #353.

3.1.4

New features

• Document and fix the patterns.meta library
• Stretchable dash patterns
• Use \protected@edef in \pgfmathparse
