That option is to disable deprecated elements in Geany's plugin API.

But using deprecated functions isn't really a problem until GTK 3.0, no?
Anyway thanks for looking at it ;-)

Either that, or use a replacement GLib function for it. I
probably wrote that code, but using the global tags autocompletion I
didn't realize it was deprecated (maybe we could use
GTK_DISABLE_DEPRECATED etc for tag file generation).

Probably we could apply this after the 0.15 release.

No idea about this - but I guess we should apply it to fix deprecation

(I really don't like GObject code in C, maybe we could use Vala for

Probably a normal Make rule could be put in src/Makefile.am to do that.

gtk_widget_set_tooltip_text() was only added in GTK+ 2.12, we still
support 2.6 (see HACKING). Maybe that function could be mimiced for GTK
< 2.12 with something like ui_widget_set_tooltip_text().

To sum up, we can probably apply all these after the 0.15 release, but
with some changes. Thanks for submitting them.
