New pkg-config name
For GtkSourceView 4, the pkg-config name is:

To compile a program that uses GtkSourceView 4, you can for example use the following command:
$ gcc hello.c `pkg-config --cflags --libs gtksourceview-4` -o hello
GtkSourceView 3.99.1
All the deprecated APIs have been removed.
Only
<gtksourceview/gtksource.h>
can be included directly. There were already warnings about it in GtkSourceView 3. The warnings have been changed to errors.Only the version 2 of the GtkSourceView language definition file format is supported (for *.lang files, used for syntax highlighting). The support for the version 1 has been dropped.

gtk_source_completion_item_new2()
has been renamed to gtk_source_completion_item_new().gtk_source_search_context_forward2()
has been renamed to gtk_source_search_context_forward().gtk_source_search_context_forward_finish2()
has been renamed to gtk_source_search_context_forward_finish().gtk_source_search_context_backward2()
has been renamed to gtk_source_search_context_backward().gtk_source_search_context_backward_finish2()
has been renamed to gtk_source_search_context_backward_finish().gtk_source_search_context_replace2()
has been renamed to gtk_source_search_context_replace().The GtkSourceSearchContext:settings property is now construct-only.
GtkSourceView 3.99.4
The API of the GtkSourceView::move-lines keybinding signal has been simplified: the
copy
parameter was deprecated and has been removed; and thecount
parameter has been replaced by thedown
boolean.
GtkSourceView 3.99.7
In order to have a better *.gir file and have less metadata to generate the *.vapi for Vala, the following change has been made:
gtk_source_completion_show()
has been renamed to gtk_source_completion_start(). The function conflicted with the GtkSourceCompletion::show signal. Note that in Vala this doesn't require code changes because the method was already renamed tostart()
in GtkSourceView 3.
Other changes in 3.99.7:
For i18n initialization, the gtk_source_init() function now needs to be called. There is also the gtk_source_finalize() function which is convenient when using memory debugging tools.
