On Wed, 20 Feb 2008, Till Tantau submitted version 2.0 of the

TikZ/pgf

package to CTAN.

PGF is a macro package for creating graphics. It is platform- and format-independent and works together with the most important TeX backend drivers, including pdftex and dvips. It comes with a user-friedly syntax layer called TikZ.

Release notes: ----------------------------------------------------------------------

This new version of the TikZ and pgf graphic packages comes with a large number of new features, too numerous to list them all. Hilights are Mark Wibrow's decoration library, Mark's new shapes, the improved notations for doing geometric drawings, fadings (the transparency version of shadings), easy shadows, improved support for systems like xetex, as well as countless bugfixes.

This version *may break existing code* (hence the big version step). We tried to make sure that 99% of all code will still work exactly as it did before and all larger documents that the developers and some volunteers tried still look exactly as they did before, but there a number of places where unavoidable changes had to be done. Known changes that break existing code:

• There was a bug in the diamond shape that caused it to be twice as

large as the minimum size required. This has been fixed. However, if you code relied on the wrong minimum size handling, your diamond shapes will now be too small.

• Snakes are now handled by decorations internally. While this offers

endless new possibilities, you are no longer allowed to use negative values with the after snake gap option. The documentation did neither explicitly allow nor forbid this, so some people may have used this.

• The basic layer has been restructured. Some things moved into the

core, other stuff moved into something new, called modules. Typically, you will not notice this at all, but it is imaginable that you may need to include a different library or module, now, to compile your code.

Also note that the PDF-file of the manual has moved to a less obscure location: It is now at .../doc/generic/pgf/pgfmanual.pdf (and no longer at .../doc/generic/pgf/version-for-pdftex/en/...)

Happy TeXing everyone, Till
