Arduino decided to make the Arduino Playground read only, so it is no longer possible for people to edit it directly. They will now need to report issues or suggestions for improvement to the arduino/Arduino issue tracker so that someone with edit privileges can make the required changes.
The reference-en repository is now being used to generate the Language Reference pages. The Language Reference translation projects also seem to be progressing.
The previous numbered format of the file made it difficult to determine which sections needed to be read depending on whether an issue report or a pull request was being submitted. This could make the task of reading the file look more daunting than it actually was.
Closes#3368
