The latest installation instructions for Valentina
Hello Linux Geeksters. As you may know, Valentina is an open-source software for creating clothing articles. Among others, it allows the users to create cloth patterns using either standard sizes or custom set of measurements, using traditional methods to create unique pattern tools.
The latest version available is Valentina 0.3.1, which has been recently released, coming with the below changes:
- Regression. Union tool doesn’t work.
- For tool Curve intersect axis fixed wrong calculation point in case with too small scene rect size.
- Fixed crash if a seam allowance doesn’t contain 0 points.
- Error in the creation of obj files.
- QMuParser. Bugfix for Bulkmode: Expressions with like “a=b, b*10” did not compute properly.
- QMuParser. Fix for ParserTokenReader::ExtractOperatorToken incorrectly uses ValidInfixOprtChars().
- Example of file name in dialog Save Layout appears only after user change format.
- Fixed regression with removing loops in seam allowance.
