Changelog for Thunderbird 98
The following WebExtension API changes were introduced in Thunderbird 98.
event onCreated — Fired when a new account has been created.
event onDeleted — Fired when an account has been removed.
event onUpdated — Fired when a property of an account has been modified. Folders and identities of accounts are not monitored by this event, use the dedicated folder and identity events instead. A changed :value:`defaultIdentity` is reported only after a different identity has been assigned as default identity, but not after a property of the default identity has been changed.
event onFileUpload.relatedFileInfo — Information about an already uploaded file, which is related to this upload.
type RelatedCloudFile — Information about an already uploaded cloud file, which is related to a new upload. For example if the content of a cloud attachment is updated, if a repeatedly used cloud attachment is renamed (and therefore should be re-uploaded to not invalidate existing links) or if the provider has its manifest property :value:`reuse_uploads` set to :value:`false`.
function getAttachmentFile — Gets the content of a compose.ComposeAttachment as a File object.
type FileAttachment — Object used to add, update or rename an attachment in a message being composed.
type MessageAttachment — Represents an attachment in a message.
