 At its core, this is a Dvorak layout, with some minor changes. The more interesting parts are how certain keys behave:
 
-* The keys on the number row double as function keys, when held for a bit longer than an usual tap. This allows me to use the function keys without having to switch layers.
+* The number row is the same as in the [ADORE](#adore-layer) layer. The function keys are on the **Media** layer.
 * The `Shift`, `Alt`, and `Control` modifiers are one-shot. When tapped, they are considered active for the next key press only. When double tapped, they toggle on, until a third, single tap sometime later. When held, they act as expected. My usual pattern is that I use these for the next keypress only, so this behaviour is perfect. If I need them held, I'll just double-tap.
 * The `GUI` key is special, because when I double-tap it, it sends `GUI + w`, which pops up an application selector. It also switches to a one-shot layer, where the number row on the left half turns into app selector macros, for the most common things I usually want to switch to. Otherwise it behaves as on a normal layout.
 * The `ESC` key also doubles as a one-shot cancel key: if tapped while any of the one-shot modifiers are in-flight (as in, single-tapped, and not expired yet), it cancels all one-shot modifiers. It also cancels the **Hun** layer, if active. Otherwise it sends the usual keycode.

How it works out in the long run remains to be seen.

 # Changelog
 
+## v1.7
+
+*2016-09-18*
+
+### Overall changes
+
+* The number row has been completely rearranged on both the [Base](#base-layer) and the [ADORE](#adore-layer) layers.
+* The number/function key behavior was changed: function keys are now on the **Media**.
+* The `:`/`;` and `-`/`_` keys were put back to their thumb position on the bottom row, on both the [Base](#base-layer) and [ADORE](#adore-layer) layers.
+* The bottom large keys on the inner side of each half now function as [tmux](http://tmux.github.io/) keys: the left to send the prefix, the right to send the `display-panes` key. The left also doubles as a GNU screen prefix key, and sends `C-a` when double tapped.
+* A number of functions, such as the **AppSel** layer, now require the `hid-commands` tool to be running, with the output of `hid_listen` being piped to it.
+
+### ADORE
+
+* `Y` and `X` have been swapped again.
+
+### Media/Navigation layer
+
+* The function keys are now on this layer.
+* Mouse keys have been removed.
+* Media start/stop/prev/next have been removed.
+* `Print screen` has been removed.
+* There is only one screen lock key now.
+
+### Heatmap
+
+* Fixed a few issues in the finger-stats calculation.
+* The tool now also timestamps and saves all input lines to a logfile, which it loads on start, allowing one to continue the collection after upgrading the tool.
+* The heatmap tool will now colorize the stats by default.
+* The periodic stats are now printed in a more compact format.
+
+### Tools
+
+* Added a new tool, `tools/layer-notify` that listens to layer change events on the HID console, and pops up a notification on layer changes.
+* Another new tool, `tools/text-to-log.py` has been added that converts arbitrary text to a keylogger output, which can be fed to the heatmap generator.
+* A number of features have been moved to the `tools/hid-commands` utility. These generally are OS dependent, and are easier to implement on the software side.

 ## Changelog
 
+* Sep 22, 2016:
+  * Created a new key in layer 1 (bottom-corner key) that resets the EEPROM.
 * Feb 2, 2016 (V1.1): 
   * Made the right-hand quote key double as Cmd/Win on hold. So you get ' when you tap it, " when you tap it with Shift, and Cmd or Win when you hold it. You can then use it as a modifier, or just press and hold it for a moment (and then let go) to send a single Cmd or Win keystroke (handy for opening the Start menu on Windows).

+# The Impossible Layout
+
+The Impossible Layout is named such because it manages to fit in both a numpad and an inverted-T arrow cluster into the same layer as the alpha keys.
+
+## Main layout
+
+The Impossible Layout places the middle column of the alphas onto where the punctuation keys were, moving he most used punctuation to be accessed by the thumbs. Because removing the middle columns fits with the Workman layout's philosopy, Workman is used as the basis for the layout. This means the layout should be very easy to learn for Workman users, and reasonable for Colemak users. Other space gains are made by combining keys that are only ever chorded with other non symbol keys (with function-layer alternatives where needed).

+
+The Qwerty layer, mostly intended for gaming use, makes use of the doubled chorded/non-symbolic keys to obtain use of the entire alpha-numeric typing area.

+## Stenography
+
+The Steno/Plover layer moves the number row below the regular keys, providing a much more comfortable placement for the thumb keys. Using this layout will require a slightly different dictionary to account for different keys being adjacent to the number row.
