-# Change log
-
-This is a listing of all changes and prototypes for the Atreus
-keyboard design. Changes to the
-[Atreus Deck](https://atreus.technomancy.us/marki) are elsewhere.
-
-## Keyboardio Atreus: 2020-03-17
-
-* Completely redesigned factory-produced case.
-* Metal switch plate.
-* USB C port.
-* Optionally labeled XDA keycaps.
-* 15mm smaller in two dimensions.
-
-## NX-04: 2019-05-25
-
-This was the first prototype to incorporate the redesigned PCB by
-Jesse Vincent.
-
-* 2 additional keys.
-* wooden case with 4 layers instead of 5.
-* detachable USB cable.
-* swappable Cherry MX switches.
-* surface-mount controller and diodes.
-* Kaleidoscope is the default firmware.
-
-## Mark 3.8: 2018-7-28
-
-* QMK is the default firmware for all boards now.
-
-## Mark 3.7: 2017-6-29
-
-* Manually bending middle switch pins on Alps is no longer necessary.
-* Spacer layer is split into three pieces to be less wasteful with materials.
-
-## Mark 3.6: 2016-3-14
-
-* TMK is the default firmware.
-* New layout with arrows on the fn layer.
-* PCB is now label-side up by default.
-
-## Mark 3.5: 2015-6-23
-
-* Change to Matias switches.
-
-## NX-03: 2015-05-08
-
-* Matias Clicky switches.
-* Alps-compatible switch plate.
-
-## Mark 3.1: 2014-11-25
-
-* [Second revision of circuit board](http://gerblook.org/pcb/jweM8BcTbgKCL4zsj8tEYj).
-* Arrows on L2 shifted over one column.
-* Circuit board license changed to match the rest of the Atreus project.
-
-The second revision of the circuit board exposes the reset pin,
-removing the need for hookup wire described below. It also removes
-[the need to cut a notch in the circuit board](https://www.flickr.com/photos/technomancy/15862732742)
-to allow the USB connector more clearance.
-
-The layout changed slightly by shifting the arrow keys on L2 over one
-column so they can be hit from the normal position without the pinky key.
-
-## Mark 3: 2014-10-30
-
-* Initial [board design](http://gerblook.org/pcb/zqMY66AEsKz3xehSrdoDV6) in KiCAD + Racket.
-* Assembly guide updated to include wood finishing.
-* Cable hole in case spacer has rounded edges.
-* New layout: multidvorak.
-* Switch to Pololu A-Star Micro controller. (also USB mini->micro)
-
-A
-[circuit board was designed in KiCAD with the switch placement logic written in Racket](http://technomancy.us/176). The
-first revision of the circuit board does not expose the reset pin, so
-hookup wire is needed to provide a backup reset mechanism once the board
-is fully assembled. The firmware contains a reset mechanism, but if
-bugs in the firmware prevent it from being activated, the back case
-can be removed and the hookup wires can be connected twice in a second
-to initiate a reset.
-
-The new design replaced the Teensy 2 microcontroller with the smaller
-[A-Star Micro](http://www.pololu.com/product/3101) which uses a USB
-Micro connector instead of USB Mini.
-
-The new multidvorak layout allows the firmware to support hardware
-dvorak and software dvorak simultaneously. The edges of the cable hole
-are rounded off to reduce strain on the cable.
-
-## NX-02: 2014-08-05
-
-* Matias Quiet Click switches.
-* Teensy 3: ARM-based microcontroller.
-* Orestes: firmware written in Forth.
-
-An
-[experimental prototype](https://www.flickr.com/photos/technomancy/14654421878)
-using Matias Quiet Click switches and the ARM-based Teensy 3
-controller. The Matias switch shape was supported by cutting the
-notches out of each switch hole individually with a knife.
-
-Porting the firmware to the ARM platform was accompanied by porting
-[an implementation of Forth](https://github.com/technomancy/orestes/tree/teensy3)
-and porting the firmware logic to that.
-
-## Mark 2: 2014-04-22
-
-* New OpenSCAD [case design](https://www.flickr.com/photos/technomancy/14719013574) by Constantine.
-* New layouts: hardware dvorak, hardware colemak.
-* Assembly guide.
-
-The case was
-[redesigned in OpenSCAD](https://github.com/technomancy/atreus/blob/master/case/openscad/atreus_case.scad)
-to be easier to produce from mail-order laser cutting services. This
-revision can be recognized by its use of eight screws instead of the
-original seven. The cuts in the top plate around the switches are also
-much closer to the switches themselves.
-[A second independent build](http://geekhack.org/index.php?topic=57007.msg1292144)
-was documented.
-
-The assembly process is documented properly.
-
-## Mark 1: 2014-04-01
-
-* Custom Atreus firmware in C.
-* Layout changes; new layer.
-
-A
-[custom Atreus-specific firmware codebase](https://github.com/technomancy/atreus-firmware)
-was started. Digits were moved to a numpad arrangement and the L2
-layer (function and arrow keys) was added. The first
-[third-party build](http://blog.tarn-vedra.de/2014/04/reproducing-keyboard-science_1707.html)
-was documented.
-
-## NX-01: 2014-02-22
-
-* [Initial prototype](https://www.flickr.com/photos/technomancy/12805226463)!
-* Case hand-drawn in Inkscape.
-* Teensy 2 microcontroller, hand-wired matrix.
-* Uses TMK firmware.
-
-This was the first Atreus,
-[created solely for personal use](http://technomancy.us/173) and
-meticulously hand-wired with a number of errors. Support for the
-Atreus was
-[added to the TMK firmware codebase](https://github.com/technomancy/tmk_keyboard/tree/atreus),
-but power-saving bugs in TMK meant that it occasionally dropped key
-presses on low-voltage laptops.
