Please try this out, as we’re planning to release 1.0 soon (around Sept. 15th).
There’s lots of new stuff, including progress bar and status bar board and serial port displayed ported over from Wiring. Also, URLs in the IDE are now clickable, so you can go straight to documentation for the examples. There’s something of a list on the wiki: http://code.google.com/p/arduino/wiki/Arduino1
The improvements are thanks in large part to the efforts of Christian Maglie, who’s been working with Arduino for a while now and has been helping out with the software for the last few weeks. Thanks Christian!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
