+Git v1.8.1 Release Notes
+========================
+
+Backward compatibility notes
+----------------------------
+
+In the next major release (not *this* one), we will change the
+behavior of the "git push" command.
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there). We will use the "simple" semantics that pushes the
+current branch to the branch with the same name, only when the current
+branch is set to integrate with that remote branch. There is a user
+preference configuration variable "push.default" to change this, and
+"git push" will warn about the upcoming change until you set this
+variable in this release.
+
+"git branch --set-upstream" is deprecated and may be removed in a
+relatively distant future. "git branch [-u|--set-upstream-to]" has
+been introduced with a saner order of arguments.
+
+
+Updates since v1.8.0
+--------------------
+
+UI, Workflows & Features
+
+ * We used to have a workaround for a bug in ancient "less" that
+ causes it to exit without any output when the terminal is resized.
+ The bug has been fixed in "less" version 406 (June 2007), and the
+ workaround has been removed in this release.
+
+ * A new configuration variable "diff.context" can be used to
+ give the default number of context lines in the patch output, to
+ override the hardcoded default of 3 lines.
+
+ * "git format-patch" leraned the "--notes=<ref>" option to give
+ notes for the commit after the three-dash lines in its output.
+
+ * "git log --grep=<pcre>" learned to honor the "grep.patterntype"
+ configuration set to "perl".
+
+ * "git rm $submodule" used to punt on removing a submodule working
+ tree to avoid losing the repository embedded in it. Because
+ recent git uses a mechanism to separate the submodule repository
+ from the submodule working tree, "git rm" learned to detect this
+ case and removes the submodule working tree when it is safe.
+
+ * "git submodule add" learned to add a new submodule at the same
+ path as the path where an unrelated submodule was bound to in an
+ existing revision via the "--name" option.
+
+ * "git submodule sync" learned the "--recursive" option.
+
+ * "git symbolic-ref" learned the "-d $symref" option to delete the
+ named symbolic ref, which is more intuitive way to spell it than
+ "update-ref -d --no-deref".
+
+
+Foreign Interface
+
+ * "git cvsimport" can be told to record timezones (other than GMT)
+ per-author via its author info file.
+
+ * The remote helper interface to interact with subversion
+ repositories (one of the GSoC 2012 projects) has been merged.
+
+
+Performance, Internal Implementation, etc.
+
+ * The logic to generate the initial advertisement from
+ "upload-pack" (what is invoked by "git fetch" on the other side
+ of the connection) to list what refs are available in the
+ repository has been optimized.
+
+ * The logic to find set of attributes that match a given path has
+ been optimized.
+
+
+Also contains minor documentation updates and code clean-ups.
+
+
+Fixes since v1.8.0
+------------------
+
+Unless otherwise noted, all the fixes since v1.8.0 in the maintenance
+track are contained in this release (see release notes to them for
+details).

+ * The configuration parser had an unnecessary hardcoded limit on
+ variable names that was not checked consistently.

-----------
Given two arguments, creates or updates a symbolic ref <name> to

+Given `--delete` and an additional argument, deletes the given

A symbolic ref is a regular file that stores a string that

a regular file whose contents is `ref: refs/heads/master`.

This uses two files, $GIT_DIR/info/allowed-users and
allowed-groups, to describe which heads can be pushed into by
whom. The format of each file would look like this:
- refs/heads/master junio

- refs/heads/cogito$ pasky
- refs/heads/bw/.* linus
- refs/heads/tmp/.* .*
- refs/tags/v[0-9].* junio

+ +refs/heads/pu junio
+ refs/heads/cogito$ pasky
+ refs/heads/bw/.* linus
+ refs/heads/tmp/.* .*
+ refs/tags/v[0-9].* junio
With this, Linus can push or create "bw/penguin" or "bw/zebra"
or "bw/panda" branches, Pasky can do only "cogito", and JC can
do master and pu branches and make versioned tags. And anybody
can do tmp/blah branches. The '+' sign at the pu record means
that JC can make non-fast-forward pushes on it.

Fetching Data From a Server
-===========================
+---------------------------
When one Git repository wants to get data that a second repository
has, the first can 'fetch' from the second. This operation determines

Pushing Data To a Server

+------------------------
Pushing data to a server will invoke the 'receive-pack' process on the
server, which will allow the client to tell it which references it should

+Shallow commits
+===============
+
+.Definition
+*********************************************************
+Shallow commits do have parents, but not in the shallow
repo, and therefore grafts are introduced pretending that
these commits have no parents.
+*********************************************************
The basic idea is to write the SHA1s of shallow commits into
$GIT_DIR/shallow, and handle its contents like the contents
only one ancestor or remote fits; a '^' means all of the ancestors
must be the same.
-case ancest head remote result

Only #2ALT and #3ALT use *empty*, because these are the only cases
where there can be conflicts that didn't exist before. Note that we
will produce a numbered series of files in the current directory, one
for each patch in the current branch but not in origin/HEAD.
+`git format-patch` can include an initial "cover letter". You can insert
+commentary on individual patches after the three dash line which
+`format-patch` places after the commit message but before the patch
+itself. If you use `git notes` to track your cover letter material,
+`git format-patch --notes` will include the commit's notes in a similar
+manner.
+
You can then import these into your mail client and send them by
hand. However, if you have a lot to send at once, you may prefer to
use the linkgit:git-send-email[1] script to automate the process.

+# - Hard coded "lines: +2 -3" placeholder, instead of real numbers.
+# - CVS normally does not internally add a blank first line
+# nor a last line with nothing but a space to log messages.
+# - The latest cvs 1.12.x server sends +0000 timezone (with some hidden "MT"
+# tagging in the protocol), and if cvs 1.12.x client sees the MT tags,
+# it converts to local time zone. git-cvsserver doesn't do the +0000
+# or the MT tags...
+# - The latest 1.12.x releases add a "commitid:" field on to the end of the
+# "date:" line (after "lines:"). Maybe we could stick git's commit id
+# in it? Or does CVS expect a certain number of bits (too few for
+# a full sha1)?
+#
+# Given the above, expect the following test to break if git-cvsserver's
+# log output is improved. The test is just to ensure it doesn't
+# accidentally get worse.
