## [`v94.3.0`](https://github.com/elastic/eui/releases/v94.3.0)

- Updated `launch` glyph for `EuiIcon`
([#7670](elastic/eui#7670))
- Updated `EuiComboBox`'s `options` to support including tooltip details
for selectable options. Use `toolTipContent` to render tooltip
information, and `toolTipProps` to optionally customize the tooltip
rendering behavior ([#7700](elastic/eui#7700))
- Updated the following existing glyphs in `EuiIcon`:
([#7727](elastic/eui#7727))
  - `error` (now an outlined version instead of filled) 
  - `tokenMetricCounter`
  - `tokenMetricGauge` 
- Added the following new glyphs to `EuiIcon`:
([#7727](elastic/eui#7727))
  - `tokenDimension`
  - `clickLeft`
  - `clickRight`
  - `clockCounter`
  - `errorFilled` (the previous `error` glyph design)
  - `warningFilled`

**Bug fixes**

- Fixed a visual layout bug for `EuiComboBox` with `isLoading` in mobile
views ([#7700](elastic/eui#7700))
- Fixed missing styles on header cells of `EuiDataGrid` that prevented
content text alignment styles to apply
([#7720](elastic/eui#7720))
- Fixed `EuiFlexGroup` and `EuiFlexItem` `ref` prop typing to support
refs of the same type as the passed `component` type and allow
`displayName` to be defined for easy component naming when using
component wrappers like `styled()`
([#7724](elastic/eui#7724))

---

Most of the code changes you'll see in this PR are caused by the recent
EuiFlex* changes making it generic. This, unfortunately, is something
that `styled()` doesn't always like. I replaced the failing usages of
`styled(EuiFlexGroup)` and `styled(EuiFlexItem)` to use `component` and
other native EuiFlex* props, resulting in the same output but being
better typed.

We plan to add more props to EuiFlex* components giving developers
control over properties like `flex-grow` and `flex-shring`, and reducing
the need for writing any custom CSS when using these components. This
should reduce the number of `styled()` wrappers needed even further
