## [8.1.0] – 2023-07-06 ### Added - On non-Windows platforms, new `-Tvt100` and `-Tvt100-24bit` output formats are available that do rudimentary rendering to a terminal that supports ANSI escape sequences. - Some notes about the interaction with wide-oriented streams were added to the cgraph man page. ### Changed - When memory allocation failures cause Graphviz to exit, information about the failing allocation is included in the error message. ### Fixed - Failure of arrowhead and arrowtail to respect penwidth #372 \ Fixed also for the `curve` and `icurve` [edge arrow shapes](https://graphviz.org/doc/info/arrows.html#primitive-shapes). - Iteration calculations based on `nslimit` and/or `nslimit1` attributes are clamped to `[0, INT_MAX]`. That is, calculations that result in a negative number of iterations are rounded up to `0` and those that result in a number of iterations that exceeds `INT_MAX` are rounded down to `INT_MAX`. Iteration numbers outside this range do not have useful behavior, but could be caused unintentionally by users. - Setting `xdotversion` attributes that parse as greater than 17 (`xdotversion` is parsed as a series of digits, ignoring all non-digits) no longer causes an out of bounds read when rendering to xdot. #2390 - Icon size in the macOS Graphviz.app has been fixed so icons are no longer invisible. - Compiling the portable source tarball on a machine with SWIG ≥ 4.1.0 no longer fails due to missing PHP files. #2388 - Syntax for a loop in `gvmap.sh` has been corrected. This was a regression in Graphviz 2.50.0. #2404 |
