Here are the topics that have been cooking. Commits prefixed with
'-' are only in 'pu' (proposed updates) while commits prefixed with
'+' are in 'next'. The ones marked with '.' do not appear in any of
the integration branches, but I am still holding onto them.
Git 2.27 has been tagged, and the first batch of topics (including
the "throw protocol v2 to the experimental group of features" thing)
have been merged to the 'master' branch. I'm planning to rewind the
tip of 'next' in a not-so-distant future.
Seeing a handful of regression reports [*] immediately after a
feature release is made gives me a mixed feeling: people are eager
enough to help by reporting issues they encounter, but there are not
enough people who are eager enough to help by testing the tip of
'master' before the release. Are there things we can do to help
them become early adopters so that they do not have to scramble
after the release?

* en/fast-import-looser-date (2020-05-31) 1 commit
(merged to 'next' on 2020-05-31 at 49de9c07c5)
+ fast-import: add new --date-format=raw-permissive format
Some repositories in the wild have commits that record nonsense
committer timezone (e.g. rails.git); "git fast-import" learned an
option to pass these nonsense timestamps intact to allow recreating
existing repositories as-is.
* jn/experimental-opts-into-proto-v2 (2020-05-21) 1 commit
(merged to 'next' on 2020-05-24 at 53cd664dfe)
+ config: let feature.experimental imply protocol.version=2
"feature.experimental" configuration variable is to let volunteers
easily opt into a set of newer features, which use of the v2
transport protocol is now a part of.

* lo/sparse-universal-zero-init (2020-05-24) 1 commit
(merged to 'next' on 2020-05-24 at 1f4ea6b348)
+ sparse: allow '{ 0 }' to be used without warnings
We've adopted a convention that any on-stack structure can be
initialized to have zero values in all fields with "= { 0 }", even
when the first field happens to be a pointer, but sparse complained
that a null pointer should be spelled NULL for a long time. Start
using -Wno-universal-initializer option to squelch it.

The error message from "git checkout -b foo -t bar baz" was
confusing.

* dr/push-remoteref-fix (2020-04-23) 1 commit
- remote.c: fix handling of %(push:remoteref)
The "%(push:remoteref)" placeholder in the "--format=" argument of
"git format-patch" (and friends) only showed what got explicitly
configured, not what ref at the receiving end would be updated when
"git push" was used, as it ignored the default behaviour (e.g. update
the same ref as the source).
