# Useful things in newer versions
## Windows
### Windows Vista
### Windows 7
### Windows 8
### Windows 8.1
## 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
- according to Company, we connect to insert-text for that
- 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)
- 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
not yet in Ubuntu Utopic (14.10)
- 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)
## Cocoa
### Mac OS X 10.7
- Foundation ([full details](https://developer.apple.com/library/mac/releasenotes/Foundation/RN-FoundationOlderNotes/#//apple_ref/doc/uid/TP40008080-TRANSLATED_CHAPTER_965-TRANSLATED_DEST_0))
- can use [ClassName class] == nil to test for feature existence at class level
- NSUserDefaults is now thread-safe and respects user IDs
- NSProcessInfo is now thread-safe
- NSProcessInfo has automatic termination; might want to watch for this
- NSLinguisticTrigger
- NSCalendar changes (important for date/time pickers)
- AppKit ([full details](https://developer.apple.com/library/mac/releasenotes/AppKit/RN-AppKitOlderNotes/#X10_7Notes)
- Cocoa decides when to draw focus rings
- lots of resolution independence stuff
- window edge resize/live resize
- restorable state
- toolbar versioning
- better scroll wheel management
- multi-image dragging (TODO didn't GTK+ add this too)
- built-in full screen (TODO what was fullscreen like before?)
- NSTextFinder for a standard search for text bar
- NSPasteboard: no longer need to invoke -[NSPasteboard types]
- NSPasteboards use UTIs for type information
- NOTE FROM LEOPARD: full-width cells, source lists
- view-based NSTableViews and NSOutlineViews
- URLs returned may not be file:// anymore! TODO note in futureplans.md
- **NSPopover**
- vertical text support improved
- **placeholder text in NSTextField now shown when focused**
- NSTextView now has an optional formatting bar
### Mac OS X 10.8
- Foundation ([full details](https://developer.apple.com/library/mac/releasenotes/Foundation/RN-FoundationOlderNotes/#//apple_ref/doc/uid/TP40008080-TRANSLATED_CHAPTER_965-TRANSLATED_DEST_999B))
- 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]
### Mac OS X 10.9
- Foundation ([full details](https://developer.apple.com/library/mac/releasenotes/Foundation/RN-Foundation/))
- system-provided progress reporting/cancellation support
- NSURLComponents
- **NSCalendar, NSDateFormatter, and NSNumberFormatter are now thread-safe**
- various NSCalendar and NSDateComponents improvements
- AppKit ([full details](https://developer.apple.com/library/mac/releasenotes/AppKit/RN-AppKit/))
- sheet handling is now block-based, queued, and in NSWindow; the delegate-based NSApplication API will still exist, except without the queue
- similar changes to NSAlert
- **return value changes to NSAlert**
- window visibility APIs (occlusion)
- NSApplicationActivationPolicyAccessory
- fullscreen toolbar behavior changes
- status items for multiple menu bars
- better NSSharingService support
- a special accelerated scrolling mode, Responsive Scrolling; won't matter for us since I plan to support the scroll wheel and it won't
- 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**
- view-specific RTL overrides
