Subject: [PATCH] Upgrade EUI to v79.0.1 (#156925)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary

`eui@77.2.2` ⏩ `eui@79.0.1`

🦴 The primary changes in this upgrade are around the deprecated
`EuiLoadingContent` being removed in favor of `EuiSkeletonText`.
- Most instances have been a [direct swap of
usage](https://github.com/elastic/kibana/pull/156925/commits/327626a7bef0484016d09a2dc2fd62cc03a15edc),
but [some replacements were a bit more
opinionated](https://github.com/elastic/kibana/pull/156925/commits/e6ceb36a7504aa742a440aa7d78e79f790511cab)
as I saw them as potential to take advantage of `EuiSkeletonText`'s
syntactical sugar and screen reader announcements for when state
switches to loaded.

---

## [`79.0.1`](https://github.com/elastic/eui/tree/v79.0.1)

**Bug fixes**

- Fixed broken push `EuiFlyout` behavior
([#6764](https://github.com/elastic/eui/pull/6764))


## [`79.0.0`](https://github.com/elastic/eui/tree/v79.0.0)

- Updated all `EuiSkeleton` components with new props that allow for
more control over screen reader live announcements:
`announceLoadingStatus`, `announceLoadedStatus`, and `ariaLiveProps`
([#6752](https://github.com/elastic/eui/pull/6752))
- Improved keyboard accessibility in `EuiPageHeader` by ensuring the
right side menu items come into focus from left to right.
([#6753](https://github.com/elastic/eui/pull/6753))

**Breaking changes**

- Removed deprecated `EuiLoadingContent`. Use the `EuiSkeleton`
components instead. ([#6754](https://github.com/elastic/eui/pull/6754))


## [`78.0.0`](https://github.com/elastic/eui/tree/v78.0.0)

- Improved the contrast ratio of `EuiCheckbox`, `EuiRadio`, and
`EuiSwitch` in their unchecked states to meet WCAG AA guidelines.
([#6729](https://github.com/elastic/eui/pull/6729))
- Added React Testing Library `*ByTestSubject` custom commands to
`within()`. RTL utilities can be imported from
`@elastic/eui/lib/test/rtl`.
([#6737](https://github.com/elastic/eui/pull/6737))
- Updated `EuiAvatar` to support a new letter `casing` prop that allow
customizing text capitalization
([#6739](https://github.com/elastic/eui/pull/6739))
- Updated `EuiFocusTrap` to support the `gapMode` prop configuration
(now defaults to `padding`)
([#6744](https://github.com/elastic/eui/pull/6744))

**Bug fixes**

- Fixed inconsistency in `EuiSearchBar`'s AND/OR semantics between DSL
and query string generation
([#6717](https://github.com/elastic/eui/pull/6717))
- Fixed `EuiFieldNumber`'s native browser validity detection causing
extra unnecessary rerenders
([#6741](https://github.com/elastic/eui/pull/6741))
- Fixed the `scrollLock` property on `EuiFocusTrap` (and other
components using `EuiFocusTrap`, such as `EuiFlyout` and `EuiModal`) to
no longer block scrolling on nested portalled content, such as combobox
dropdowns ([#6744](https://github.com/elastic/eui/pull/6744))

**Breaking changes**

- `EuiAvatar`s with the default `user` type will now default to
capitalizing all initials in uppercase
([#6739](https://github.com/elastic/eui/pull/6739))
