 ## [2.5.7] - 2022-09-08
 ### Changed
+- Since the fonttools library offers similar functionality, the dependency to "svg.path" is gone again, thanks to @gmischler; [#525](https://github.com/PyFPDF/fpdf2/issues/525)
 - HTML headings are now rendered with an additional leading of 20% the font size above and below them; [#520](https://github.com/PyFPDF/fpdf2/issues/520)
 - `fpdf2` now uses [fontTools](https://fonttools.readthedocs.io/en/latest/) to read and embed fonts in the PDF, thanks to @gmischler and @RedShy

 It is a fork and the successor of `PyFPDF` (_cf._ [history](https://pyfpdf.github.io/fpdf2/Development.html#history)).
 Compared with other PDF libraries, `fpdf2` is **fast, versatile, easy to learn and to extend** ([example](https://github.com/digidigital/Extensions-and-Scripts-for-pyFPDF-fpdf2)).
 It is also entirely written in Python and has very few dependencies:
