- [API] lsquic_engine_connect() can now be passed QUIC version to use. - [OPTIMIZATION] Queue opportunistic ACKs if there is data to be sent. - [BUGFIX] Don't evict streams from priority iterator if there is only one queue. - [OPTIMIZATION, BUGFIX] Several other optimizations and bug fixes. - Use ls-qpack v0.10.7.
