converse.js

:lock: This release adds support for OMEMO:2 encryption. :lock:

• #1472: feat(omemo): remember the per-chat encryption (on/off) state across chat-close and re-login

• #2097: fix(omemo): surface an error for an undecryptable OMEMO message instead of silently dropping it when it carries no fallback body

• #2336: fix(omemo): hide the encryption toggle on an untrusted device, where OMEMO can't be used

• #2606: fix(omemo): hiding media now also hides decrypted OMEMO media instead of re-rendering it

• #2632: fix(omemo): preserve the original filename when downloading a received encrypted image

• #4041: fix: strip trailing slashes from assets_path to prevent double-slash asset URLs

• #4076: fix(omemo): don't send encrypted MUC messages to banned (outcast) or non-affiliated occupants

• Remove client-compress and use browser APIs

• feat(pubsub): Add new API methods to create, subscribe and unsubscribe.

• feat(version): Add XEP-0092 Software Version support and show the server's software version in the profile modal

• feat: add support for OMEMO 2 (urn:xmpp:omemo:2), using Stanza Content Encryption (XEP-0420)

• fix(omemo): Detect omemo:2-only contacts as OMEMO-capable

• fix(omemo): Enable self-healing of abandoned or unpublished bundle

• fix(omemo): Gracefully handle contact device listed but bundle not published

• fix(theme): Clear the background class list before setting theme attributes.

• fix: Prior theme CSS class is not removed when changing the theme dynamically.

• fix: isTrustedIdentity in OMEMO store wasn't properly loading the identity

• fix: broadcast presence when the chat status (show) is cleared

• fix: the idle status flag could never be cleared, leaving stale idle presence after the user became active again

• refactor: Drop deprecated Karma test runner and Jasmine testing library and use Vitest instead.

Backwards incompatible changes

• OMEMO now uses a WebAssembly crypto module (libomemo). If you serve Converse under a strict Content-Security-Policy, you must add 'wasm-unsafe-eval' to your script-src directive, otherwise OMEMO fails to initialize with a WebAssembly.instantiate() CSP error. This token is much narrower than 'unsafe-eval' (it permits WASM compilation only).
  See the security docs for the recommended CSP.
• api.modal.show no longer takes a modal instance as first parameter
• The CJS build has been removed. Only ESM builds are produced. If you include Converse via a <script> tag, you must add type="module": <script type="module" src="converse.js"></script>. Any inline scripts calling converse.initialize() must also use type="module".
• #2405: Hide the trusted device login checkbox when persistent browser storage is unavailable.
