https://linear.app/zed-industries/issue/Z-1818/toggling-the-outline-pane-causes-the-pane-to-zoom

Add release note lines here:

- Fixed a bug that could cause panes to be erroneously zoomed when
toggling modals. (preview-only)

For some reason the yellow I used for the modified color in light themes
was really light
.
Release Notes:

* Improved the contrast of diff modified color in the editor in light
themes.

This adds basic ability to interact with OpenAI inside a buffer.

Release Notes:

* If`OPENAI_API_KEY` is defined in your environment, you can now run the
`ai: assist` command to pass the text of your current buffer to GPT-4.
If you're editing a file with a `.zmd` extension, you can also invoke
the model with `cmd-enter.` (preview-only)

This makes the `Toggle{Left,Right,Bottom}Dock` actions deserializable
from empty JSON, so that they can be constructed for the command
palette. It also fixes a bug in GPUI's `available_actions` method, in
which we'd include key bindings for actions of the same type but
different values.

Note that, for now, the command palette will perform the *focusing*
version of the actions. I'm not totally sure this is the right behavior,
but it seems more useful to me.

In this pull request we improved key bindings (as described below) and
added tooltips.

Add these release notes to the panels release notes:

- The left, right and bottom dock can be toggled and focused at the same
time respectively via `cmd-b`, `cmd-r` and `cmd-j`. Holding `shift` will
toggle them without changing the focus.

Also, bind the same keys with shift to toggle the dock without focusing.

Fixes
https://linear.app/zed-industries/issue/Z-987/option-enter-doesnt-open-buffer-from-multibuffer-if-on-the-last-line

This was caused by seeking with a right bias, which in the case of the
last excerpt in the buffer would seek past the end of the buffer. This
commit changes the behavior to move the cursor back to the previous
excerpt if we overshoot, to ensure we always land on an excerpt.

Release Notes:

- Fixed a bug that prevented opening excerpts when the cursor was at the
end of a multi-buffer.

Closes
https://linear.app/zed-industries/issue/Z-1789/empty-panes-should-not-be-zoomable

The actions in Zed now call this the Terminal Panel and the crate is
called that as well, so I think the tooltip should be updated to use
that same name.
