## 🧹 AI Flag Cleanup Summary
This PR removes the `improvedJsonDiff` feature flag, making the enhanced
JSON
diffing component the default and only option. The now-unused legacy
diff
component and all related feature flag logic have been removed to
streamline the
codebase.
### 🚮 Removed
- **Components**
- `OldEventDiff` component was removed, along with its helper types and
constants.
- **Flag Logic**
- All conditional rendering based on the `improvedJsonDiff` flag was
removed.
- The `sort` prop from `EventDiff` was removed as it was only used by
the
legacy component.
- **Configuration**
- `improvedJsonDiff` flag definition was removed from `uiConfig.ts`,
`experimental.ts`, and `server-dev.ts`.
- **Tests**
- Mock configuration for `improvedJsonDiff` in tests was removed.
### 🛠 Kept
- **Components**
- `NewEventDiff` was renamed to `EventDiff` and is now the standard
implementation.
### 📝 Why
The `improvedJsonDiff` feature flag was marked as completed with its
outcome
being "kept". This cleanup finalizes the feature rollout by removing the
flag
and associated legacy code, simplifying the implementation and reducing
code
complexity.

We're migrating to ESM, which will allow us to import the latest
versions of our dependencies.

Moves the event timeline to the personal dashboard from the header when
the `frontendHeaderRedesign` flag is active.
When the flag is active, it also:
- hides the event timeline and corresponding button in the header
- renders the environment selector next to the time selector instead of
at the other end of the header

Fixes browser console warnings and errors related to the event timeline
and strategy form.
- **Event Timeline**: Addressed a warning where the environment filter
rendered with a default environment value (production) before
environments were fully loaded.
- **Strategy Form**: Resolved an error caused by forwarding the enabled
prop as a boolean.
Follow-up to: https://github.com/Unleash/unleash/pull/8642
Introduces a reusable `Highlight` component that leverages the Context
API pattern, enabling highlight effects to be triggered from anywhere in
the application.
This update refactors the existing highlight effect in the event
timeline to use the new Highlight component and extends the
functionality to include the Unleash AI experiment, triggered by its
entry in the "New in Unleash" section.
https://linear.app/unleash/issue/2-2743/open-the-signal-query-endpoint-to-everyone-not-only-admins
The new signal query endpoint is now open for every Unleash user, not
only admins.
This PR allows non-admins to view signals in the event timeline. It also
updates the signals tooltip to be shown to all users, not just admins,
under the following assumptions:
- `!signalsSuggestionSeen` - Current user has not dismissed the signals
tip
- `isEnterprise()` - Enterprise instance
- `signalsEnabled` - The signals feature flag is enabled
- `!signalsLoading` - Signals have finished loading (avoids flickering)
- `signals.length === 0` - We can't find any signals in the selected
timespan
https://linear.app/unleash/issue/2-2729/add-event-timeline-to-new-in-unleash
Adds the new event timeline to the "New in Unleash" section.
Unlike Signals & Actions, the Event timeline doesn’t have a dedicated
page to link to, as it's a global component within the layout. To
address this, we extend the "check it out" action in the New in Unleash
component by supporting a callback instead of a link. When the user
clicks "check it out" for this new item, the page smoothly scrolls to
the top, ~~the timeline opens (if it's not already)~~, and a temporary
highlight effect is triggered on the timeline header button.
Also includes some scouting / slight UX adjustments.

https://linear.app/unleash/issue/2-2723/add-signals-tip
Adds a tip to the event timeline regarding the usage of signals.
The conditions for it to show up are the following:
- `!signalsSuggestionSeen` - The current user has not closed the tip yet
- `isEnterprise()` - The Unleash instance is an Enterprise instance
(signals are currently Enterprise-only)
- `isAdmin` - The current user is an admin (signals are currently
admin-only)
- `signalsEnabled` - The signals feature flag is currently enabled
- `!loading` - Signal endpoints have not finished loading (prevents
flickering)
- `signalEndpoints.length === 0` - The Unleash instance currently has
zero configured signal endpoints (signals feature is not being used)

https://linear.app/unleash/issue/2-2703/align-with-ux
Timeline UI/UX improvements after sync with UX, including:
- Added some spacing between each event in the grouping tooltip
- Aligned the x events occurred header with filter dropdown
- Improved the strategy icon somewhat so it doesn't look as off center
- New timeline icon
- Improve icon position relative to timestamp on each event in the
grouping tooltip
- Changed text color in dropdowns to a lighter gray
- Removed bold formatting in tooltip
- Adjusted paddings and margins
- Added close button
- Added shadow
- Added left border
There are a few details missing, which will be tackled in separate PRs.

https://linear.app/unleash/issue/2-2665/show-signals-in-the-event-timeline
Implements signals in the event timeline.
This merges events and signals into a unified `TimelineEvent`
abstraction, streamlining the data structure to only include properties
relevant to the timeline.
Key changes:
- Refactors the timeline logic to handle both events and signals through
the new abstraction.
- Introduces the `useSignalQuery` hook, modeled after `useEventSearch`,
as both serve similar purposes, albeit for different resource types.
Note: The signals suggestion alert is not included and will be addressed
in a future task.

Fixes 2 bugs:
- The initial state of the event timeline should have `open: false`, not
`true` - Closed by default, unless opened
- The event timeline should unmount when hidden - It should not emit
requests when closed
https://linear.app/unleash/issue/2-2700/persist-timeline-state-in-local-storage
Implements persistent state management for the event timeline using
local storage.
I believe this improves UX by persisting both the timeline toggle
(visibility) state and applied filters across page refreshes.
Includes some scouting/refactoring and some workarounds to prevent the
timeline from animating on page load (in most cases).

(In the video, you’ll notice a slight delay before new events show up.
This happens because the timeline automatically refreshes every 10
seconds)
Removes the event timeline from the event log and integrates it into a
new header option.
I chose a middle-ground approach between options 1 and 2 from our Figma
sketches. This solution provides the best of both worlds IMO: the
timeline stands out as a global component, distinct from the current
page context, while sliding in rather than overlapping the content. This
way, users can view the timeline alongside the page content.
https://linear.app/unleash/issue/2-2664/implement-event-tooltips
Implements event tooltips in the new event timeline.
This leverages our current `feature-event-formatter-md` to provide both
a label and a summary of the event. Whenever our new `eventTimeline`
flag is enabled, we enrich our events in our event search endpoint with
this information. We've discussed different options here and reached the
conclusion that this is the best path forward for now. This way we are
being consistent, DRY, relatively performant and it also gives us a
happy path forward if we decide to scope in the event log revamp, since
this data will already be present there.
We also added a new `label` property to each of our event types
currently in our event formatter. This way we can have a concise,
human-readable name for each event type, instead of exposing the
internal event type string.
~~We also fixed the way the event formatter handled bold text (as in,
**bold**). Before, it was wrapping them in *single asterisks*, but now
we're using **double asterisks**. We also abstracted this away into a
helper method aptly named `bold`. Of course, this change meant that a
bunch of snapshots and tests needed to be updated.~~
~~This new `bold` method also makes it super easy to revert this
decision if we choose to, for any reason. However I believe we should
stick with markdown formatting, since it is the most commonly supported
formatting syntax, so I see this as an important fix. It's also in the
name of the formatter (`md`). I also believe bold was the original
intent. If we want italic formatting we should implement it separately
at a later point.~~
Edit: It was _bold_ of me to assume this would work out of the box on
Slack. It does when you manually try it on the app, but not when using
the Slack client. See: https://github.com/Unleash/unleash/pull/8222


Adds tests for event log filters (to ensure we show the right filters)
and refactors the implementation of eventlogfilters.
Primary goal of refactoring:
- Make it so that all filters are created in one single list (instead of
injected from different variables)
- Avoid making a requests for features (and to a lesser extent:
projects) if you can't use them for filters
- Improve code structure
