@subheading What is Google Summer of Code?
-A global program run by Google that offers students stipends for working
-on open source software projects during summer vacations.
+@uref{https://developers.google.com/open-source/gsoc/, GSoC} is a global
+program that offers students stipends to write code for free software
+and open source projects during the summer. It is an excellent
+opportunity for students to gain experience with real-world software
+development and make a contribution that benefits everyone. It brings
+new contributors to LilyPond and enables students who are already
+involved to become more involved. LilyPond participates in GSoC as part
+of the @uref{http://www.gnu.org/, GNU project}.
-It is an excellent opportunity to find new contributors, and encourage
-students already participating in LilyPond development, to become more
-involved. One of our contributors was accepted in the 2012 program as
-part of the @uref{http://www.gnu.org/, GNU project}; and we are always
-looking for others to participate in future programs.
+We have had GSoC participants in 2012, 2015 and 2016 and encourage students
+to apply for future summers.
+
+If you have questions or would like to apply, send us an email on our
+developer mailing list (see @ref{Contact}).

-@subheading Our Ideas List
+@subheading Project Ideas List
+
+Below is a list of suggested projects for GSoC or for anyone who is
+interested in helping to improve LilyPond. (Last updated: November 2016)
-Below is a list of projects that were suggested for the GSoC 2012
-students and is retained here as an inspiration for anyone
-who is interested in developing LilyPond for future GSoC projects.
+Mentor availability varies from project to project and from year to year.
+Send us an email on our developer mailing list (see @ref{Contact}), and
+we will help you find a mentor for a project that fits your interests
+and skills.
-There are many more things that can be done to improve LilyPond and
-members of the LilyPond development team are always willing to help
-those who would like to tackle projects such as those listed below.
+If you have ideas for a GSoC project that is not listed below you can
+send us an email as well. There are a number of areas where LilyPond
+could be improved, and our development team is always willing to help
+those who would like to tackle a project like those listed below.

-@subheading Grace notes
+@subheading Improve internal chord structure
-Fix problems with synchronization of grace notes. Grace notes can
-intefere with LilyPond's timing and cause odd effects, especially when
-multiple staffs are used where some have grace notes and others don't.
+The internal representation of LilyPond chords is not powerful enough
+to capture the nomenclature of jazz chords. Currently the chord has
+a root, a bass and an inversion. It would be nice to be able to handle
+stacked or polychords, minor/major, etc. In order to do this, an
+internal representation with the ability to capture the essence of
+complex chords must be developed. As a bonus, once the internal
+representation is developed, the output formatting of chord names can
+be improved.

+@subheading Adopt the SMuFL music font encoding standard
-@divClass{column-center-middle-color3}
-@subheading Improve slurs and ties
+For several years now a new standard for music fonts has been around:
+@uref{http://www.smufl.org/, SMuFL}, which is also discussed as becoming part of
+a future W3C standard for music encoding. As a FLOSS tool LilyPond should
+adhere to such an open standard instead of using an isolated solution like it
+does today. Adopting SMuFL will help integrating LilyPond with the world of
+music notation software and eventually give LilyPond users access to a wider
+selection of notation fonts.
-The default curves of slurs and ties are often unsatisfactory. Ties
-@q{broken} by clef or staff changes are not handled well. The project
-could include collecting and sorting examples of bad output, deciding on
-the intended output and writing code to improve them.
+Making LilyPond compliant to SMuFL includes remapping of the glyphs that are
+built from METAFONT sources, adjusting the glyphs' metrics to SMuFL's
+specifications, and finally updating the way LilyPond looks up and positions the
+glyphs. As an optional part of this project LilyPond's font loading mechanism
+could be modified to use notation fonts installed as system fonts instead of
+inside the LilyPond installation.
