* Two more open questions I'd like your feedback on are available [here](https://github.com/andlabs/libui/issues/48) and [here](https://github.com/andlabs/libui/issues/25).
* Sometime in the next 48 hours (before 23:59 EDT on 24 May 2016) I will split `uiCombobox` into two separate controls, `uiCombobox` and `uiEditableCombobox`, each with slightly different events and "selected item" mechanics. Prepare your existing code.
* Now that Ubuntu 16.04 LTS is here, no earlier than next Saturday, 28 May 2016 at noon EDT, **I will bump the minimum GTK+ version from 3.4 to 3.10**. This will add a lot of new features that I can now add to libui, such as search-oriented uiEntries, lists of arbitrary control layouts, and more. If you are still running a Linux distribution that doesn't come with 3.10, you will either need to upgrade or use jhbuild to set up a newer version of GTK+ in a private environment.
* You can decide if I should also drop OS X 10.7 [here](https://github.com/andlabs/libui/issues/46).
* Added `uiRadioButtonsSelected()`, `uiRadioButtonsSetSelected()`, and `uiRadioButtonsOnSelected()` to control selection of a radio button and catch an event when such a thing happens.
* Added `uiNewPasswordEntry()`, which creates a new `uiEntry` suitable for entering passwords.
* Added `uiNewSearchEntry()`, which creates a new `uiEntry` suitable for searching. On some systems, the `OnChanged()` event will be slightly delayed and/or combined, to produce a more natural feel when searching.
* Two OS X-specific functions have been added: `uiDarwinMarginAmount()` and `uiDarwinPaddingAmount()`. These return the amount of margins and padding, respectively, to give to a control, and are intended for container implementations. These are suitable for the constant of a NSLayoutConstraint. They both take a pointer parameter that is reserved for future use and should be `NULL`.
* uiDrawTextLayout attributes are now specified in units of *graphemes* on all platforms. This means characters as seen from a user's perspective, not Unicode codepoints or UTF-8 bytes. So a long string of combining marker codepoints after one codepoint would still count as one grapheme.
* As promised, `uiCombobox` is now split into `uiCombobox` for non-editable comboboxes and `uiEditableCombobox` for editable comboboxes. Mind the function changes as well :)
* There is a new function `uiMainStep()`, which runs one iteration of the main loop. It takes a single boolean argument, indicating whether to wait for an event to occur or not. It returns true if an event was processed (or if no event is available if you don't want to wait) and false if the event loop was told to stop (for instance, `uiQuit()` was called).
* Removed `uiControlVerifyDestroy()`; that is now part of `uiFreeControl()` itself.
* Added `uiPi`, a constant for π. This is provided for C and C++ programmers, where there is no standard named constant for π; bindings authors shouldn't need to worry about this.
* Fixed uiMultilineEntry not properly having line breaks on Windows.
* Added `uiNewNonWrappingMultilineEntry()`, which creates a uiMultilineEntry that scrolls horizontally instead of wrapping lines. (This is not documented as being changeable after the fact on Windows, hence it's a creation-time choice.)
* uiAreas on Windows and some internal Direct2D areas now respond to `WM_PRINTCLIENT` properly, which should hopefully increase the quality of screenshots.
* uiDateTimePicker on GTK+ works properly on RTL layouts and no longer disappears off the bottom of the screen if not enough room is available. It will also no longer be marked for localization of the time format (what the separator should be and whether to use 24-hour time), as that information is not provided by the locale system. :(
* Added `uiUserBugCannotSetParentOnToplevel()`, which should be used by implementations of toplevel controls in their `SetParent()` implementations. This will also be the beginning of consolidating common user bug messages into a single place, though this will be one of the only few exported user bug functions.
* Microsoft Visual Studio 2013 or newer (2013 is needed for `va_copy()`) — you can build either a static or a shared library
* MinGW-w64 (other flavors of MinGW may not work) — **you can only build a static library**; shared library support will be re-added once the following features come in:
* [Isolation awareness](https://msdn.microsoft.com/en-us/library/aa375197%28v=vs.85%29.aspx), which is how you get themed controls from a DLL without needing a manifest
Pass `-DBUILD_SHARED_LIBS=OFF` to `cmake` to build a static library. The standard cmake build configurations are provided; if none is specified, `Debug` is used.
If you use a makefile generator with cmake, then
```
$ make
$ make tester # for the test program
$ make examples # for examples
```
and pass `VERBOSE=1` to see build commands. Build targets will be in the `build/out` folder.
Project file generators should work, but are untested by me.
On Windows, I use the `Unix Makefiles` generator and GNU make (built using the `build_w32.bat` script included in the source and run in the Visual Studio command line). In this state, if MinGW-w64 (either 32-bit or 64-bit) is not in your `%PATH%`, cmake will use MSVC by default; otherwise, cmake will use with whatever MinGW-w64 is in your path. `set PATH=%PATH%;c:\msys2\mingw(32/64)\bin` should be enough to temporarily change to a MinGW-w64 build for the current command line session only if you installed MinGW-w64 through [MSYS2](https://msys2.github.io/); no need to change global environment variables constantly.
libui was originally written as part of my [package ui for Go](https://github.com/andlabs/ui). Now that libui is separate, package ui has become a binding to libui. As such, package ui is the only official binding.
Other people have made bindings to other languages:
