// 3: TrackKindPriority and related sorting changes.
// 5: Move a large number of items off frontendLocalState and onto state.
// 6: Common PivotTableConfig and pivot table specific PivotTableState.
// 7: Split Chrome categories in two and add 'symbolize ksyms' flag.
// 8: Rename several variables
// "[...]HeapProfileFlamegraph[...]" -> "[...]Flamegraph[...]".
// 9: Add a field to track last loaded recording profile name
// 10: Change last loaded profile tracking type to accommodate auto-save.
// 11: Rename updateChromeCategories to fetchChromeCategories.
// 12: Add a field to cache mapping from UI track ID to trace track ID in order
//     to speed up flow arrows rendering.
// 13: FlamegraphState changed to support area selection.
// 14: Changed the type of uiTrackIdByTraceTrackId from `Map` to an object with
// typed key/value because a `Map` does not preserve type during
// serialisation+deserialisation.
// 15: Added state for Pivot Table V2
// 16: Added boolean tracking if the flamegraph modal was dismissed
// 17:
// - add currentEngineId to track the id of the current engine
// - remove nextNoteId, nextAreaId and use nextId as a unique counter for all
//   indexing except the indexing of the engines
// 18: areaSelection change see b/235869542
// 19: Added visualisedArgs state.
// 20: Refactored thread sorting order.
// 21: Updated perf sample selection to include a ts range instead of single ts
// 22: Add log selection kind.
// 23: Add log filtering criteria for Android log entries.
// 24: Store only a single Engine.
// 25: Move omnibox state off VisibleState.
// 26: Add tags for filtering Android log entries.
// 27. Add a text entry for filtering Android log entries.
// 28. Add a boolean indicating if non matching log entries are hidden.
// 29. Add ftrace state. <-- Borked, state contains a non-serializable object.
// 30. Convert ftraceFilter.excludedNames from Set<string> to string[].
// 31. Convert all timestamps to bigints.
// 32. Add pendingDeeplink.
// 33. Add plugins state.
// 34. Add additional pendingDeeplink fields (query, pid).
// 35. Add force to OmniboxState
// 36. Remove metrics
// 37. Add additional pendingDeeplink fields (visStart, visEnd).
// 38. Add track tags.
// 39. Ported cpu_slice, ftrace, and android_log tracks to plugin tracks. Track
//     state entries now require a URI and old track implementations are no
//     longer registered.
// 40. Ported counter, process summary/sched, & cpu_freq to plugin tracks.
// 41. Ported all remaining tracks.
// 42. Rename trackId -> trackKey.
// 43. Remove visibleTracks.
// 44. Add TabsV2 state.
// 45. Remove v1 tracks.
// 46. Remove trackKeyByTrackId.
// 47. Selection V2

// 52. Update track group state - don't make the summary track the first track.
// 53. Remove android log state.
// 54. Remove traceTime.
// 55. Rename TrackGroupState.id -> TrackGroupState.key.
// 56. Renamed chrome slice to thread slice everywhere.
