Sometimes latest versions of the software can cause issues when installed on older devices or devices running an older version of the operating system. Software makers usually fix these issues but it can take them some time. What you can do in the meantime is to download and install an older version of Arduino 1.6.6.

What's new in this version:

IDE:
- Switched to Java 8, which is now both bundled and needed for compiling the IDE
- Added link to unofficial boards support list in preferences
- Limit of possible new sketches in a day raised to 676. Thanks @Chris--A
- Windows: fixed a bug when running username had non ASCII chars
- Lots of fixes
- ArduinoISP examples moved under 11.ArduinoISP folder
- MacOSX: binary is now able to tell the IDE its current working directory. Eases life to those using the IDE from the CLI
- CLI: if specified board doesn't exist, fail instead of using a default one
- Windows: IDE stores its stuff under %LOCALAPPDATA% instead of %APPDATA% (which was a roaming folder). %APPDATA% content is automatically migrated to new location
- Added 74880 baud rate to serial monitor. Thanks @Chris--A
- When changing tab, file name is shown in window title
- IDE groups compiled files into "libraries", "core" and "sketch" folders
- Added Serial Plotter. Thanks @henningpohl
- Editor: triple click selects whole line
- Windows: IDE startup feels faster
- Examples of libraries with a .development flag file in their root folder won't get marked as read-only. See #2619
- Update notifications: when updates are available from either Library or Boards Managers, a popup will be shown
- Introducing arduino-builder, a command line tool that properly calls gcc. Fixes lots of issues about buggy preprocessing.
- Each open sketch gets built in its own folder, allowing the IDE to recycle previous compilations and being much faster
- "Go to line": CTRL+L or Edit > Go to line... will open a dialog where you can type the line number where you want the editor to jump to
- Added boards.local.txt support: like platform.local.txt, allows to enrich a boards.txt definition without modifying the original file. Thanks @Wackerbarth
- Library to library dependencies: when your sketch imports a library, and that library uses another, the IDE will find out without you having to add a useless #include to your sketch
- Allow per-platform keywords.txt. Thanks @PaulStoffregen
- Allow spaces in IDE install path on Linux. Thanks @matthijskooijman
- Fixed a lot of documentation. Thanks to @per1234 @q2dg
- Fixed parsing for SystemProfiler when scanning for available serial ports on Macosx El Capitan

Libraries:
- Bridge: YunClient.connected() returns true if there are bytes available for read. Thanks @RobAtticus
- Bridge: YunClient.stop() now empties all buffers. Thanks @RobAtticus
- Ethernet: Added missing keywords. Thanks @per1234
- Ethernet: Fixed DNSClient.inet_aton() function. Thanks @jhorck
- Ethernet: Expose optional DHCP timout parameters to Ethernet:begin(). Thanks @chaveiro
- Wire: Implemented Wire.end().
- Wire: Fixed bug with repeated START for AVR. Thanks Nate Williams
- Wire: Resolved timing issues on AVR. See #2173 #1477.
- Wire: Fixed bug in repeated start in slave mode on SAM. See #3908
- SD: Change "char *" to "const char *" on methods accepting a string as a parameter. Thanks @Ivan-Perez
- Scheduler: Added support for cortex-M0. Thanks @PeterVH

Core:
- Added new PluggableUSB and HID support. This change introduces a more powerful API for
- libraries that wants use advanced features of USB-Device.
- Thanks to @obra @NicoHood @matthijskooijman @nospam2000 @weizenspreu
- AVR: fixed wrong turnOffPWM() for TIMER0B. Thanks @gonzoveliki
- AVR: added support for AtmegaXXu2. Thanks @NicoHood
- AVR: a bunch of USB Core bug fix. Thanks @NicoHood
- AVR: Expose serial setting from USB-CDC serial port. Thanks @matthijskooijman
- ArduinoISP is now compatible with every architecture (not only AVR) and is much more stable. Thanks @PeterVH
- Print not aborting on write() failure. Thanks @stickbreaker
- AVR: Faster interrupts patch. Thanks @xxxajk
- AVR: Fixed pulseInLong wrong measurements.
- AVR: Removed a bunch of compiler warnings. Thanks @NicoHood
- Improved variants files for Boards Gemma and Ethernet
