Chores

• binaries: Lets switch to prebuild! (#1282) (8c36e99)

BREAKING CHANGES

• binaries: We switched to prebuild a breaking change because it's substantially changes our install processes. It's also possible the install flags to ensure downloading or building from source has changed slightly. That's not our api per say, but it's enough.
• windows: We previously hard coded to have RTS on for windows at all times it now default to off.

• docs: add missing parsers to properties list (3faadac)

• open: Throw on incorrect baudrate option (#1347) (a3b8d35)

• parsers: Add cctalk parsers (#1342) (bcb492f)

This is a bug fix release that includes one of the best bug fixes we could ask for. @dustmop has rewritten our windows read/write subsystem! This should bring reads and writes down from 100% cpu to 1-2% cpu. Give it a try!

Nearly a year in the making Node SerialPort 5.0.0 is a major rewrite that improves stability, compatibility and performance. The api surface is similar to version 4 there have been a number of changes to ensure consistent error handling and operation of a serial port. Notably we are now a Stream! We also introduced a bindings layer. A small low level api to provide access to underlying hardware. External bindings written in other languages or targeting other platforms can now be used.

Some major cpu performance gains on unix platforms can be found and we're less buggy and better performing on Windows too.

With this release we are now only supporting LTS nodejs platforms and we are dropping NodeJS 0.10, 0.12, 5 and 7 support. We loved directly supporting so many platforms but it was getting in the way making a solid library.

See our upgrade guide for detail on what to change to upgrade your app to use [email protected]. It's not much!

Thank you to the 25 people who committed code and documentation and every person who submitted bug reports and tested changes!

Fixes

We also had help testing, debugging, and designing from; @alaq @arve0 @techninja @noopkat @HipsterBrown and more!

If we're lucky this will be the last of the betas. The remaining potentially blocking issues have to do with improving SerialPort.list which would change their output. The two issues are #1220 and #1084. I need help on those two issues, if I'm not able to close them soon, I'll release anyway, and they'll be fixed for 6x. This release is large enough. -@reconbot
