## Bug fixes

- Pausing uploads doesn't work well with matrix.org
- Quickly posting with another account leads to sync stop
- CPU usage
- `code` not colored in room subtitle
- In the "Leave me" room, "join > Hi > left" aren't combined
- Event delegates changing height don't scroll the list

  - Ensure all the text that should be copied is copied
  - Multiple messages are currently copied out of order

- Pressing backspace in composer sometimes doesn't work
- Message order isn't preserved when sending a first message in a E2E
  room, then while keys are being shared sending one with another account,
  then sending one with the first account again

- If account not in config anymore, discard ui state last page on startup
- Do something when access token is invalid

- Don't store states in delegates
- [hr not working](https://bugreports.qt.io/browse/QTBUG-74342)
- Terrible performance using `QT_QPA_PLATFORM=wayland-egl`, must use `xcb`
- Quote links color in room subtitles (e.g. "> http://foo.orgA)" )

## Interface

    - Fetch all members when using the filter members bar

- Direct chats category
- Animate RoomEventDelegate DayBreak apparition
- Live-reloading accounts.json

- E2E
  - Device verification
  - Edit/delete own devices
  - Request room keys from own other devices
  - Auto-trust accounts within the same client
  - Provide help when undecryptable messages occur, including:
    - Trigger `nio.AsyncClient.request_room_key`
    - Option to export-logout-login-import to fix one-time key problems
- Read receipts
- Status message and presence

## Nio contributions

- Dedicated error for invalid password on key import

## Notable changes for future Qt version upgrade

### [Qt 5.13](https://wiki.qt.io/New_Features_in_Qt_5.13)

- Added `SplitView`
- Added `cache` property to icon

### [Qt 5.14](https://wiki.qt.io/New_Features_in_Qt_5.14)

- Applications can now opt-in to use non-integer scale factors.
  Use `QGuiApplication::highDpiScaleFactorRoundingPolicy`.

- Added `qmlRegisterSingletonInstance` function.
  This allows to expose a QObject as a singleton to QML, without having to
  create a factory function as required by `qmlRegisterSingletonType`.
  It is meant as a type safe replacement of `setContextProperty`.

- Added `qmlRegisterAnonymousType` as a replacement for `qmlRegisterType`.
  It allows to specify the URI and major version for better tooling support.

- qmllint gained an experimental -U option. If run with it, it warns about 
  about accesses to unqualified identifiers

- `Text` and `TextEdit` now support Markdown format
  (CommonMark and GitHub dialects) as an alternative to HTML.
  Includes the GitHub checklist extension, such that you can click to toggle
  checkboxes in a `TextEdit`.

- `TextEdit` uses an I-beam cursor by default, and a pointing-hand cursor when
  hovering a checkbox or a link

- Added `WheelHandler`, an Event Handler for the mouse wheel, and optionally
  for emulated mouse wheel events coming from a trackpad.

- Added `BoundaryRule` in Qt.labs.animation: a `PropertyValueInterceptor` that
  restricts the range of values a numeric property can have, applies
  "resistance" when the value is overshooting, and provides the ability to
  animate it back within range. It's particularly useful in combination with
  `WheelHandler`, to provide similar physics as Flickable has.

- `Image` and `BorderImage` now have the same `currentFrame` and `frameCount`
  properties that `AnimatedImage` has; this allows choosing an individual icon
  from an .ICO file that contains multiple icons, for example.
  In the future it's intended to support other multi-page formats such as
  PDF, TIFF and WEBP.
