Removal of threading functions</h2>
<p>The threading functions have been removed, including the per-thread sleep function.

These libraries implement a usable subset of the threading APIs in C++11 and C11, and in fact some GLFW 3 test programs use TinyCThread.</p>
<p>However, GLFW 3 has better support for <em>use from multiple threads</em> than GLFW 2 had. Contexts can be made current on any thread, although only a single thread at a time, and the documentation explicitly states which functions may be used from any thread and which must only be used from the main thread.</p>

Physical key input</h2>
<p>GLFW 3 key tokens map to physical keys, unlike in GLFW 2 where they mapped to the values generated by the current keyboard layout. The tokens are named according to the values they would have using the standard US layout, but this is only a convenience, as most programmers are assumed to know that layout. This means that (for example) <code>GLFW_KEY_LEFT_BRACKET</code> is always a single key and is the same key in the same place regardless of what keyboard layouts the users of your program has.</p>
<p>The key input facility was never meant for text input, although using it that way worked slightly better in GLFW 2. If you were using it to input text, you should be using the character callback instead, on both GLFW 2 and 3. This will give you the characters being input, as opposed to the keys being pressed.</p>
<p>GLFW 3 has key tokens for all keys on a standard 105 key keyboard, so instead of having to remember whether to check for <code>'a'</code> or <code>'A'</code>, you now check for <code>GLFW_KEY_A</code>.</p>
