 ### Deprecated
 - the font caching mechanism, that used the `pickle` module, has been removed, for security reasons,
-  and because it provided little performance, and only for specific use cases - _cf._ [issue #345](https://github.com/PyFPDF/fpdf2/issues/345).
+  and because it provided little performance gain, and only for specific use cases - _cf._ [issue #345](https://github.com/PyFPDF/fpdf2/issues/345).
   That means that the `font_cache_dir` optional parameter of `fpdf.FPDF` constructor
   and the `uni` optional argument of `FPDF.add_font()` are deprecated.
   The `fpdf.fpdf.load_cache` function has also been removed.
