News in 1.5.1, 2017-04-23
-------------------------
This is an unstable release in the 1.5 development cycle. The 1.6 stable
version will be released at the same time as GNOME 3.26.

* Change underline type to PANGO_UNDERLINE_SINGLE, to remove the workaround for
  the GtkTextView bug where wavy underlines are not properly removed:
  https://bugzilla.gnome.org/show_bug.cgi?id=763741
* Up to 20x faster implementation for the GtkTextView inline spell-checker, to
  fix a responsiveness problem when editing long lines.
* Rework symbol visibility handling, by using the -export-dynamic LDFLAG
  and -fvisibility=hidden CFLAG, instead of the -export-symbols-regex LDFLAG.
* Add note for packagers in the README file: aspell doesn't work well with
  gspell, hunspell is preferred.
* Various other small improvements.
* Translation updates.
