A new version of the Arduino IDE (1.6.3) is available at the download page!
The Arduino IDE 1.6.3 is a bug fix release: after having released 1.6.2 with new libraries and cores managers, we received lots of useful feedback and fixed a handful of bugs.

In particular:

• Fixed some impolite crashes on some Linux distributions
• Bundled AVR core files are back into hardware folder
• Fixed “https” links not working on Windows and Mac
• Added new Arduino Language color highlight
• Introduced a way to help old cores to work with newer IDEs without having to upgrade their code
• Advise of duplicate libraries after compiling. Thanks @PaulStoffregen

As usual, the complete list of fixes and credits is available here.

Don’t forget to check out the Library Manager: at the time of writing, 144 libraries are listed, thanks to the contributions of Paul Stoffregen and Adafruit.

Just a quick note on the Arduino Language color coding, we assigned different colors to the three Language categories listed in the Arduino Reference. Structure keywords are green, variables are teal, while functions stays orange. We did a lot of user testing on these new color highlights, and it is helpful for beginners to have a bit more of a visual cue when starting to write code.

Don’t forget to report any issue you find, either on Github or on the Arduino forum: your help is very much appreciated. It doesn’t matter if you are not a tech specialist: every feedback adds value.

Happy hacking!
