The default of 7 comes from fairly early in git development, when
seven hex digits was a lot (it covers about 250+ million hash
values). Back then I thought that 65k revisions was a lot (it was what
we were about to hit in BK), and each revision tends to be about 5-10
new objects or so, so a million objects was a big number.
These days, the kernel isn't even the largest git project, and even
the kernel has about 220k revisions (_much_ bigger than the BK tree
ever was) and we are approaching two million objects. At that point,
seven hex digits is still unique for a lot of them, but when we're
talking about just two orders of magnitude difference between number
of objects and the hash size, there _will_ be collisions in truncated
hash values. It's no longer even close to unrealistic - it happens all
the time.
We should both increase the default abbrev that was unrealistically
small, _and_ add a way for people to set their own default per-project
in the git config file.
This is the first step to first make it configurable; the default of 7
is not raised yet.

This reverts commit 72a5b561fc, as adding
fixed number of hexdigits more than necessary to make one object name
locally unique does not help in futureproofing the uniqueness of names
we generate today.

Users are sometimes confused with two different types of "tracking" behavior
in Git: "remote-tracking" branches (e.g. refs/remotes/*/*) versus the
merge/rebase relationship between a local branch and its @{upstream}
(controlled by branch.foo.remote and branch.foo.merge config settings).
When the push.default is set to 'tracking', it specifies that a branch should
be pushed to its @{upstream} branch. In other words, setting push.default to
'tracking' applies only to the latter of the above two types of "tracking"
behavior.
In order to make this more understandable to the user, we rename the
push.default == 'tracking' option to push.default == 'upstream'.
push.default == 'tracking' is left as a deprecated synonym for 'upstream'.

A new whitespace "rule" is added that sets the tab width to use for
whitespace checks and fix-ups and replaces the hard-coded constant 8.
Since the setting is part of the rules, it can be set per file using
.gitattributes.
The new configuration is backwards compatible because older git versions
simply ignore unknown whitespace rules.

The "[add] ignore-errors" tweakable introduced by v1.5.6-rc0~30^2 (Add
a config option to ignore errors for git-add, 2008-05-12) does not
follow the usual convention for naming values in the git configuration
file.
What convention? Glad you asked.
The section name indicates the affected subsystem.
The subsection name, if any, indicates which of
an unbound set of things to set the value for.
The variable name describes the effect of tweaking
this knob.
The section and variable names can be broken into
words using bumpyCaps in documentation as a hint to
the reader. These word breaks are not significant
at the level of code, since the section and variable
names are not case sensitive.
The name "add.ignore-errors" includes a dash, meaning a naive
configuration file like
[add]
ignoreErrors
does not have any effect. Avoid such confusion by renaming to the
more consistent add.ignoreErrors, but keep the old version for
backwards compatibility.

different pager for various subcommands (e.g., because they
use different less settings for "log" vs "diff", or because
they have a pager that interprets only log output but not
other commands).

only boolean to-page-or-not-to-page, but also to specify a

The new boolean "fetchRecurseSubmodules" config option controls the
behavior for "git fetch" and "git pull". It specifies if these commands
should recurse into submodules and fetch new commits there too and can be
set separately for each submodule.
In the .gitmodules file "submodule.<name>.fetchRecurseSubmodules" entries
are read before looking for them in .git/config. Thus settings found in
.git/config will override those from .gitmodules, thereby allowing the
user to ignore settings given by the remote side while also letting
upstream set reasonable defaults for those users who don't have special
needs.
This configuration can be overridden by the command line option
"--[no-]recurse-submodules" of "git fetch" and "git pull".

Even though git makes sure that it uses enough hexdigits to show an
abbreviated object name unambiguously, as more objects are added to the
repository over time, a short name that used to be unique will stop being
unique. Git uses this many extra hexdigits that are more than necessary
to make the object name currently unique, in the hope that its output will
stay unique a bit longer.
