Bugfixes and enhancements in the main application.
Olympus IX83 users: please use 1.4.21 instead.
If you use AndorSDK3 (Andor sCMOS cameras) and experience a crash upon starting Micro-Manager (or loading a hardware configuration), please upgrade to the 20150820 nightly build (Windows 64-bit, Windows 32-bit).
Under GNU/Linux platforms, you should compile micro-manager from source.
(OS X 10.8 and later: if the application does not open when double-clicked for the first time, try ctrl-click or right click, then select 'Open'.) Device drivers may have other requirements.
