+## GTK+
+TODO what ships with Ubuntu Quantal (12.10)?
+
+### GTK+ 3.6
+ships with: Ubuntu Raring (13.04)
+
+- GtkEntry and GtkTextView have input purposes and input hints for external input methods but do not change input themselves

+- GtkLevelBar
+- GtkMenuButton
+- **GtkSearchEntry**
+
+### GTK+ 3.8
+ships with: Ubuntu Saucy (13.10)
+
+Not many interesting new things to us here, unless you count widget-internal tickers and single-click instead of double-click to select list items (a la KDE)... and oh yeah, also widget opacity.
+
+### GTK+ 3.10
+ships with: **Ubuntu Trusty (14.04 LTS)**
+<br>GLib version: 2.40
+
+- tab character stops in GtkEntry
+- GtkHeaderBar
+	- intended for titlebar overrides; GtkInfoBar is what I keep thinking GtkHeaderBar is
+- **GtkListBox**
+- GtkRevealer for smooth animations of disclosure triangles
+- GtkSearchBar for custom search popups
+- **GtkStack and GtkStackSwitcher**
+- titlebar overrides (seems to be the hot new thing)
+
+### GTK+ 3.12
+ships with: Ubuntu Utopic (14.10)
+<br>GLib version: 2.42
+
+- GtkActionBar (basically like the bottom-of-the-window toolbars in Mac programs)
+- gtk_get_locale_direction(), for internationalization
+- more control over GtkHeaderBar
+- **GtkPopover**
+	- GtkPopovers on GtkMenuButtons
+- GtkStack signaling
+- **gtk_tree_path_new_from_indicesv()** (for when we add Table if we have trees too)
+
+### GTK+ 3.14
+ships with: **Debian Jessie**, Ubuntu Vivid (15.04)
+<br>GLib version: Debian: 2.42, Ubuntu: 2.44
+
+- gestures
+- better GtkListbox selection handling
+- more style classes (TODO also prior?)
+- delayed switch changes on GtkSwitch
+
+### GTK+ 3.16
+ships with: Ubuntu Wily (15.10)
+<br>GLib version: 2.46
+
+- gtk_clipboard_get_default() (???)
+- **GtkGLArea**
+- proper xalign and yalign for GtkLabel; should get rid of runtime deprecation warnings
+- better control of GtkListBox model-based creation (probably not relevant but)
+- GtkModelButton (for GActions; probably not relevant?)
+- wide handles on GtkPaned
+- GtkPopoverMenu
+- IPP paper names in GtkPaperSize (TODO will this be important for printing?)
+- multiple matches in GtkSearchEntry (TODO evaluate priority)
+- **GtkStackSidebar**
+-  GTK_STYLE_CLASS_LABEL, GTK_STYLE_CLASS_MONOSPACE, GTK_STYLE_CLASS_STATUSBAR, GTK_STYLE_CLASS_TOUCH_SELECTION, GTK_STYLE_CLASS_WIDE (TODO figure out which of these are useful)
+- GtkTextView: extend-selection
+- GtkTextView: font fallbacks

+	- NSDateComponents supports leap months
+	- NSNumberFormatter and NSDateFormatter default to 10.4 behavior by default (need to explicitly do this on 10.7)
+	- **NSUserNotification and NSUserNotificationCenter for Growl-style notifications**
+	- better linguistic triggers for Spanish and Italian
+	- NSByteCountFormatter
+- AppKit ([full details](https://developer.apple.com/library/mac/releasenotes/AppKit/RN-AppKitOlderNotes/#X10_8Notes))
+	- view-based NSTableView/NSOutlineView have expansion tooltips
+	- NSScrollView magnification
+	- Quick Look events; TODO see if they conflict with keyboard handling in Area
+	- NSPageController (maybe useful?)
+	- not useful for package UI, but may be useful for a new library (probably not by me): NSSharingService
+	- NSOpenPanel and NSSavePanel are now longer NSPanels or NSWindows in sandboxed applications; this may be an issue should anyone dare to enable sandboxing on a program that uses package ui
+	- NSTextAlternatives
+	- -[NSOpenGLContext setFullScreen] now ineffective
+	- +[NSColor underPageBackgroundColor]
+

+	- **return value changes to NSAlert**
+	- window visibility APIs (occlusion)
+	- NSApplicationActivationPolicyAccessory
+	- fullscreen toolbar behavior changes
+	- status items for multiple menu bars

+	- NSScrollView live scrolling notifications
+	- NSScrollView floating (anchored/non-scrolling) subviews
+	- better multimonitor support
+	- better key-value observing for NSOpenPanel/NSSavePanel (might want to look this up to see if we can override some other juicy details... TODO)
+	- better accessory view key-view handling in NSOpenPanel/NSSavePanel
+	- NSAppearance
+	- **-[NSTableView moveRowAtIndex:toIndex:] bug regarding first responders fixed**
