Release neqo v0.8.1

[mxinden]

Follow-up to #1971.

Depends on:

• refactor(server): remove ServerConnectionIdGenerator #1981

Ideally includes:

• feat(transport): Use a shorter ECN probe threshold initially #1964
• chore(neqo-udp): drop tokio dependency #1988
• [breaking] deps(udp): make tracing optional and add optional log quinn-rs/quinn#1921
  • Merged through [non-breaking] deps(udp): make tracing optional and add optional log quinn-rs/quinn#1923
  • Note that this does not require a patch to mozilla/neqo, given that it is released as non-breaking and can thus simply be updated in mozilla-central directly.

All but #1964 are merged. #1964 is not needed for Fast UDP for Firefox milestone 1. As planned today, milestone 1 will not come with ECN support. That will be rolled out with milestone 2.

I suggest proceeding here, i.e. releasing v0.8.1.

@KershawChang do you have the time to cut a release?

I am happy to do it myself, though I would need to be given permissions, which I assume I will need longterm anyways. I think Write permissions would suffice. //CC @larseggert since I think you manage mozilla/neqo's GitHub permissions.

[KershawChang]

Yeah, I can release v0.8.1 today.

[mxinden]

Thank you @KershawChang. Want me to replace https://phabricator.services.mozilla.com/D216265 or are you going to update it?

I'll update it. Thanks.

Note that #1988 requires the following change to http3server:

We probably need to do 0.8.2 soon, when there is a proper fix in #1998.

[mxinden]

Given the importance of #1998, writing up my understanding below to make sure I am not missing something.

The bug introduced in #1603, to be fixed in #1998, has been released in v0.6.9. Thus it is released in Firefox for quite some time.

Neqo v0.8.1 does not introduce this bug, nor does it worsen it. Thereby we don't need to block the roll-out of v0.8.1 in Firefox on #1998, https://phabricator.services.mozilla.com/D217271 respectively.

Please correct me if I am wrong.

[larseggert]

Correct

[mxinden]

Closing here since v0.8.1 has been released.

We can include #1998 in v0.8.2 or, my preference, in an upcoming v0.8.3.
