In 1999-2000, URW++ Design and Development GmbH released Type 1
implementations of the Core 35 fonts under the GNU General Public License
(GPL) and the Aladdin Ghostscript Free Public License (AFPL). In 2009, URW++
additionally released the same fonts under the LaTeX Project Public License
(LPPL).
In 2016, URW++ released a major Version 2.0 upgrade to the Core 35 fonts.
This version is an extensive reworking of the original Core 35 fonts, with
improved font outlines, and greatly extended character sets, including
Cyrillic and Greek. Also, some font names were changed. Version 2.0 was
released in Type 1, OpenType-CFF and OpenType-TTF formats. URW++ released
Version 2.0 of the fonts under the GNU Affero General Public License, Version
3 (AGPL) with an exemption.
In 2017, URW++ additionally released the same Version 2.0 fonts under the
LaTeX Project Public License (LPPL) Version 1.3c, and under the SIL Open Font
License (OFL), Version 1.1, without a "Reserved Font Name" clause.
In 2020, MuseScore BVBA released the Edwin font family, a renamed version of
the C059 font family (Roman, Italic, Bold & Bold Italic) from the Core 35 font
set. This was done in order to make modifications that suit the requirements
of the open source notation software, MuseScore. It is released under the SIL
Open Font License (OFL) only.
