- Implementation of Trust Messages (XEP-0434)
- Implementation of Automatic Trust Management (XEP-0450)
- Implementations directly as part of the OMEMO plugin, since omemo:2 is the only protocol supported by ATM at the moment
- Trust system selection updated to allow choice between manual trust with ATM and BTBV
- dev-requirements.txt updated to include additional requirements for the e2e tests
fix 376
- support for both (modern) OMEMO under the `urn:xmpp:omemo:2` namespace and (legacy) OMEMO under the `eu.siacs.conversations.axolotl` namespace
- maintains one identity across both versions of OMEMO
- migrates data from the old plugin
- includes more features for protocol stability
- uses SCE for modern OMEMO
- fully type-checked, linted and format-checked
- added type hints to various pieces of backend code used by the plugin
- added stubs for some Twisted APIs used by the plugin under stubs/ (use `export MYPYPATH=stubs/` before running mypy)
- core (xmpp): enabled `send` trigger and made it an asyncPoint
fix 375
