matrix-sdk 0.16.0

You may be wondering what happened to the 0.15.0 release, and you’re right to ask. Unfortunately, it had to be yanked after a problematic Git dependency slipped through during publishing.

This created a situation where some SDK crates were successfully released as 0.15.0, while others failed to publish. To avoid confusion and maintain consistency, the entire 0.15.0 release was yanked.

  an error that occurred when importing a secret from secret storage.
  (#5647)
• [breaking] Add authentication::oauth::qrcode::login::LoginProgress::SyncingSecrets to
  indicate that secrets are being synced between the two devices.
  (#5760)
• Add authentication::oauth::OAuth::grant_login_with_qr_code to reciprocate a login by

  (#5614)

Refactor

• [breaking]: Client::server_vendor_info() requires to enable the
  federation-api feature.
  (#5912)

• [breaking]: Client::reset_server_info() has been split into
  reset_supported_versions() and reset_well_known().
  (#5910)

• [breaking]: Client::send() has extra bounds where
  Request::Authentication: AuthScheme<Input<'a> = SendAccessToken<'a>> and
  Request::PathBuilder: SupportedPathBuilder. This method should still work for any request to the
  Client-Server API. This allows to drop the HttpError::NotClientRequest error in favor of a
  compile-time error.
  (#5781,
  #5789,
  #5815)

• [breaking]: The waveform field was moved from AttachmentInfo::Voice to BaseAudioInfo,
  allowing to set it for any audio message. Its format also changed, and it is now a list of f32
  between 0 and 1.
  (#5732)

• [breaking] The caption and formatted_caption fields and methods of AttachmentConfig,
  GalleryConfig and GalleryItemInfo have been merged into a single field that uses
  TextMessageEventContent.
  (#5733)

• The Matrix SDK crate now uses the 2024 edition of Rust.
  (#5677)

• [breaking] Make LoginProgress::EstablishingSecureChannel generic in order to reuse it
  for the currently missing QR login flow.
  (#5750)

• [breaking] The new_virtual_element_call_widget now uses a props and a config parameter instead of only props.
  This splits the configuration of the widget into required properties ("widget_id", "parent_url"...) so the widget can work
  and optional config parameters ("skip_lobby", "header", "...").
  The config option should in most cases only provide the "intent" property.
  All other config options will then be chosen by EC based on platform + intent.

  Before:

  new_virtual_element_call_widget(
    VirtualElementCallWidgetProperties {
      widget_id: "my_widget_id", // required property
      skip_lobby: Some(true), // optional configuration
      preload: Some(true), // optional configuration
      // ...
    }
  )

  Now:

  new_virtual_element_call_widget(
    VirtualElementCallWidgetProperties {
      widget_id: "my_widget_id", // required property
      // ... only required properties
    },
    VirtualElementCallWidgetConfig {
      intend: Intend.StartCallDM, // defines the default values for all other configuration
      skip_lobby: Some(false), // overwrite a specific default value
      ..VirtualElementCallWidgetConfig::default() // set all other config options to `None`. Use defaults from intent.
    }
  )

  (#5560)

Bugfix

• A new local LatestEventValue was always created as LocalIsSending. It
  must be created as LocalCannotBeSent if a previous local LatestEventValue
  exists and is LocalCannotBeSent.
  (#5908)
• Switch QR login implementation from std::time::Instant to ruma::time::Instant which
  is compatible with Wasm.
  (#5889)
