+GIT v1.5.5 Release Notes
+========================
+
+Updates since v1.5.4
+--------------------
+
+(subsystems)
+
+ * Comes with git-gui 0.9.3.
+
+(portability)
+
+ * We shouldn't ask for BSD group ownership semantics by setting g+s bit
+   on directories on older BSD systems that refuses chmod() by non root
+   users.  BSD semantics is the default there anyway.
+
+ * Bunch of portability improvement patches coming from an effort to port
+   to Solaris has been applied.
+
+(performance)
+
+ * On platforms with suboptimal qsort(3) implementation, there
+   is an option to use more reasonable substitute we ship with
+   our software.
+
+ * New configuration variable "pack.packsizelimit" can be used
+   in place of command line option --max-pack-size.
+
+ * "git fetch" over the native git protocol used to make a
+   connection to find out the set of current remote refs and
+   another to actually download the pack data.  We now use only
+   one connection for these tasks.
+
+ * "git commit" does not run lstat(2) more than necessary
+   anymore.
+
+(usability, bells and whistles)
+
+ * Bash completion script (in contrib) are aware of more commands and
+   options.
+
+ * You can be warned when core.autocrlf conversion is applied in
+   such a way that results in an irreversible conversion.
+
+ * A catch-all "color.ui" configuration variable can be used to
+   enable coloring of all color-capable commands, instead of
+   individual ones such as "color.status" and "color.branch".
+
+ * The commands refused to take absolute pathnames where they
+   require pathnames relative to the work tree or the current
+   subdirectory.  They now can take absolute pathnames in such a
+   case as long as the pathnames do not refer outside of the
+   work tree.  E.g. "git add $(pwd)/foo" now works.
+
+ * Error messages used to be sent to stderr, only to get hidden,
+   when $PAGER was in use.  They now are sent to stdout along
+   with the command output to be shown in the $PAGER.
+
+ * A pattern "foo/" in .gitignore file now matches a directory
+   "foo".  Pattern "foo" also matches as before.
+
+ * bash completion's prompt helper function can talk about
+   operation in-progress (e.g. merge, rebase, etc.).
+
+ * Configuration variables "url.<usethis>.insteadof = <otherurl>" can be
+   used to tell "git-fetch" and "git-push" to use different URL than what
+   is given from the command line.
+
+ * "git add -i" behaves better even before you make an initial commit.
+
+ * "git am" refused to run from a subdirectory without a good reason.
+
+ * After "git apply --whitespace=fix" fixes whitespace errors in a patch,
+   a line before the fix can appear as a context or preimage line in a
+   later patch, causing the patch not to apply.  The command now knows to
+   see through whitespace fixes done to context lines to successfully
+   apply such a patch series.
+
+ * "git branch" (and "git checkout -b") to branch from a local branch can
+   optionally set "branch.<name>.merge" to mark the new branch to build on
+   the other local branch, when "branch.autosetupmerge" is set to
+   "always", or when passing the command line option "--track" (this option
+   was ignored when branching from local branches).  By default, this does
+   not happen when branching from a local branch.
+
+ * "git checkout" to switch to a branch that has "branch.<name>.merge" set
+   (i.e. marked to build on another branch) reports how much the branch
+   and the other branch diverged.
+
+ * When "git checkout" has to update a lot of paths, it used to be silent
+   for 4 seconds before it showed any progress report.  It is now a bit
+   more impatient and starts showing progress report early.
+
+ * "git commit" learned a new hook "prepare-commit-msg" that can
+   inspect what is going to be committed and prepare the commit
+   log message template to be edited.
+
+ * "git cvsimport" can now take more than one -M options.
+
+ * "git describe" learned to limit the tags to be used for
+   naming with --match option.
+
+ * "git describe --contains" now barfs when the named commit
+   cannot be described.
+
+ * "git describe --exact-match" describes only commits that are tagged.
+
+ * "git describe --long" describes a tagged commit as $tag-0-$sha1,
+   instead of just showing the exact tagname.
+
+ * "git describe" warns when using a tag whose name and path contradict
+   with each other.
+
+ * "git diff" learned "--relative" option to limit and output paths
+   relative to the current directory when working in a subdirectory.
+
+ * "git diff" learned "--dirstat" option to show birds-eye-summary of
+   changes more concisely than "--diffstat".
+
+ * "git format-patch" learned --cover-letter option to generate a cover
+   letter template.
+
+ * "git gc" learned --quiet option.
+
+ * "git gc" now automatically prunes unreachable objects that are two
+   weeks old or older.
+
+ * "git gc --auto" can be disabled more easily by just setting gc.auto
+   to zero.  It also tolerates more packfiles by default.
+
+ * "git grep" now knows "--name-only" is a synonym for the "-l" option.
+
+ * "git help <alias>" now reports "'git <alias>' is alias to <what>",
+   instead of saying "No manual entry for git-<alias>".
+
+ * "git help" can use different backends to show manual pages and this can
+   be configured using "man.viewer" configuration.
+
+ * "gitk" does not restore window position from $HOME/.gitk anymore (it
+   still restores the size).
+
+ * "git log --grep=<what>" learned "--fixed-strings" option to look for
+   <what> without treating it as a regular expression.
+
+ * "git gui" learned an auto-spell checking.
+
+ * "git push <somewhere> HEAD" and "git push <somewhere> +HEAD" works as
+   expected; they push the current branch (and only the current branch).
+   In addition, HEAD can be written as the value of "remote.<there>.push"
+   configuration variable.
+
+ * When the configuration variable "pack.threads" is set to 0, "git
+   repack" auto detects the number of CPUs and uses that many threads.
+
+ * "git send-email" learned to prompt for passwords
+   interactively.
+
+ * "git send-email" learned an easier way to suppress CC
+   recipients.
+
+ * "git stash" learned "pop" command, that applies the latest stash and
+   removes it from the stash, and "drop" command to discard the named
+   stash entry.
+
+ * "git submodule" learned a new subcommand "summary" to show the
+   symmetric difference between the HEAD version and the work tree version
+   of the submodule commits.
+
+ * Various "git cvsimport", "git cvsexportcommit", "git svn" and
+   "git p4" improvements.
+
+(internal)
+
+ * Duplicated code between git-help and git-instaweb that
+   launches user's preferred browser has been refactored.
+
+ * It is now easier to write test scripts that records known
+   breakages.
+
+ * "git checkout" is rewritten in C.
+
+ * "git remote" is rewritten in C.
+
+ * Two conflict hunks that are separated by a very short span of common
+   lines are now coalesced into one larger hunk, to make the result easier
+   to read.
+
+ * Run-command API's use of file descriptors is documented clearer and
+   is more consistent now.
+
+ * diff output can be sent to FILE * that is different from stdout.  This
+   will help reimplementing more things in C.
+
+Fixes since v1.5.4
+------------------
+
+All of the fixes in v1.5.4 maintenance series are included in
+this release, unless otherwise noted.
+
+ * "git-http-push" did not allow deletion of remote ref with the usual
+   "push <remote> :<branch>" syntax.
+
+ * "git-rebase --abort" did not go back to the right location if
+   "git-reset" was run during the "git-rebase" session.
+
+ * "git imap-send" without setting imap.host did not error out but
+   segfaulted.

+An ideal patch flow

+
+ (0) You come up with an itch.  You code it up.
+
+ (1) Send it to the list and cc people who may need to know about
+     the change.
+
+     The people who may need to know are the ones whose code you
+     are butchering.  These people happen to be the ones who are
+     most likely to be knowledgeable enough to help you, but
+     they have no obligation to help you (i.e. you ask for help,
+     don't demand).  "git log -p -- $area_you_are_modifying" would
+     help you find out who they are.
+
+ (2) You get comments and suggestions for improvements.  You may
+     even get them in a "on top of your change" patch form.
+
+ (3) Polish, refine, and re-send to the list and the people who
+     spend their time to improve your patch.  Go back to step (2).
+
+ (4) The list forms consensus that the last round of your patch is
+     good.  Send it to the list and cc the maintainer.
+
+ (5) A topic branch is created with the patch and is merged to 'next',
+     and cooked further and eventually graduates to 'master'.
+
+In any time between the (2)-(3) cycle, the maintainer may pick it up
+from the list and queue it to 'pu', in order to make it easier for
+people play with it without having to pick up and apply the patch to
+their trees themselves.

 	"text" (i.e. be subjected to the autocrlf mechanism) is
 	decided purely based on the contents.
 
+core.safecrlf::
+	If true, makes git check if converting `CRLF` as controlled by
+	`core.autocrlf` is reversible.  Git will verify if a command
+	modifies a file in the work tree either directly or indirectly.
+	For example, committing a file followed by checking out the
+	same file should yield the original file in the work tree.  If
+	this is not the case for the current setting of
+	`core.autocrlf`, git will reject the file.  The variable can
+	be set to "warn", in which case git will only warn about an
+	irreversible conversion but continue the operation.
++
+CRLF conversion bears a slight chance of corrupting data.
+autocrlf=true will convert CRLF to LF during commit and LF to
+CRLF during checkout.  A file that contains a mixture of LF and
+CRLF before the commit cannot be recreated by git.  For text
+files this is the right thing to do: it corrects line endings
+such that we have only LF line endings in the repository.
+But for binary files that are accidentally classified as text the
+conversion can corrupt data.
++
+If you recognize such corruption early you can easily fix it by
+setting the conversion type explicitly in .gitattributes.  Right
+after committing you still have the original file in your work
+tree and this file is not yet corrupted.  You can explicitly tell
+git that this file is binary and git will handle the file
+appropriately.
++
+Unfortunately, the desired effect of cleaning up text files with
+mixed line endings and the undesired effect of corrupting binary
+files cannot be distinguished.  In both cases CRLFs are removed
+in an irreversible way.  For text files this is the right thing
+to do because CRLFs are line endings, while for binary files
+converting CRLFs corrupts data.
++
+Note, this safety check does not mean that a checkout will generate a
+file identical to the original file for a different setting of
+`core.autocrlf`, but only for the current one.  For example, a text
+file with `LF` would be accepted with `core.autocrlf=input` and could
+later be checked out with `core.autocrlf=true`, in which case the
+resulting file would contain `CRLF`, although the original file
+contained `LF`.  However, in both work trees the line endings would be
+consistent, that is either all `LF` or all `CRLF`, but never mixed.  A
+file with mixed line endings would be reported by the `core.safecrlf`
+mechanism.

+Crash Reports
+-------------
+If fast-import is supplied invalid input it will terminate with a
+non-zero exit status and create a crash report in the top level of
+the Git repository it was importing into.  Crash reports contain
+a snapshot of the internal fast-import state as well as the most
+recent commands that lead up to the crash.
+
+All recent commands (including stream comments, file changes and
+progress commands) are shown in the command history within the crash
+report, but raw file data and commit messages are excluded from the
+crash report.  This exclusion saves space within the report file
+and reduces the amount of buffering that fast-import must perform
+during execution.
+
+After writing a crash report fast-import will close the current
+packfile and export the marks table.  This allows the frontend
+developer to inspect the repository state and resume the import from
+the point where it crashed.  The modified branches and tags are not
+updated during a crash, as the import did not complete successfully.
+Branch and tag information can be found in the crash report and
+must be applied manually if the update is needed.

+git-web--browse(1)
+==================
+
+NAME
+----
+git-web--browse - git helper script to launch a web browser
+
+SYNOPSIS
+--------
+'git-web--browse' [OPTIONS] URL/FILE ...
+
+DESCRIPTION
+-----------
+
+This script tries, as much as possible, to display the URLs and FILEs
+that are passed as arguments, as HTML pages in new tabs on an already
+opened web browser.
+
+The following browsers (or commands) are currently supported:
+
+* firefox (this is the default under X Window when not using KDE)
+* iceweasel
+* konqueror (this is the default under KDE)
+* w3m (this is the default outside graphical environments)
+* links
+* lynx
+* dillo
+* open (this is the default under Mac OS X GUI)
+
+Custom commands may also be specified.
+
+OPTIONS
+-------
+-b BROWSER|--browser=BROWSER::
+	Use the specified BROWSER. It must be in the list of supported
+	browsers.
+
+-t BROWSER|--tool=BROWSER::
+	Same as above.
+
+-c CONF.VAR|--config=CONF.VAR::
+	CONF.VAR is looked up in the git config files. If it's set,
+	then its value specify the browser that should be used.
+
+CONFIGURATION VARIABLES
+-----------------------
+
+CONF.VAR (from -c option) and web.browser
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The web browser can be specified using a configuration variable passed
+with the -c (or --config) command line option, or the 'web.browser'
+configuration variable if the former is not used.
+
+browser.<tool>.path
+~~~~~~~~~~~~~~~~~~~
+
+You can explicitly provide a full path to your preferred browser by
+setting the configuration variable 'browser.<tool>.path'. For example,
+you can configure the absolute path to firefox by setting
+'browser.firefox.path'. Otherwise, 'git-web--browse' assumes the tool
+is available in PATH.
+
+browser.<tool>.cmd
+~~~~~~~~~~~~~~~~~~
+
+When the browser, specified by options or configuration variables, is
+not among the supported ones, then the corresponding
+'browser.<tool>.cmd' configuration variable will be looked up. If this
+variable exists then "git web--browse" will treat the specified tool
+as a custom command and will use a shell eval to run the command with
+the URLs passed as arguments.
+
+Note about git config --global
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note that these configuration variables should probably be set using
+the '--global' flag, for example like this:
+
+------------------------------------------------
+$ git config --global web.browser firefox
+------------------------------------------------
+
+as they are probably more user specific than repository specific.
+See linkgit:git-config[1] for more information about this.

+Remotes configuration API
+=========================
+
+The API in remote.h gives access to the configuration related to
+remotes. It handles all three configuration mechanisms historically
+and currently used by git, and presents the information in a uniform
+fashion. Note that the code also handles plain URLs without any
+configuration, giving them just the default information.
+
+struct remote
+-------------
+
+`name`::
+
+	The user's nickname for the remote
+
+`url`::
+
+	An array of all of the url_nr URLs configured for the remote
+
+`push`::
+
+	 An array of refspecs configured for pushing, with
+	 push_refspec being the literal strings, and push_refspec_nr
+	 being the quantity.
+
+`fetch`::
+
+	An array of refspecs configured for fetching, with
+	fetch_refspec being the literal strings, and fetch_refspec_nr
+	being the quantity.
+
+`fetch_tags`::
+
+	The setting for whether to fetch tags (as a separate rule from
+	the configured refspecs); -1 means never to fetch tags, 0
+	means to auto-follow tags based on the default heuristic, 1
+	means to always auto-follow tags, and 2 means to fetch all
+	tags.
+
+`receivepack`, `uploadpack`::
+
+	The configured helper programs to run on the remote side, for
+	git-native protocols.
+
+`http_proxy`::
+
+	The proxy to use for curl (http, https, ftp, etc.) URLs.
+
+struct remotes can be found by name with remote_get(), and iterated
+through with for_each_remote(). remote_get(NULL) will return the
+default remote, given the current branch and configuration.
+
+struct refspec
+--------------
+
+A struct refspec holds the parsed interpretation of a refspec. If it
+will force updates (starts with a '+'), force is true. If it is a
+pattern (sides end with '*') pattern is true. src and dest are the two
+sides (if a pattern, only the part outside of the wildcards); if there
+is only one side, it is src, and dst is NULL; if sides exist but are
+empty (i.e., the refspec either starts or ends with ':'), the
+corresponding side is "".
+
+This parsing can be done to an array of strings to give an array of
+struct refpsecs with parse_ref_spec().
+
+remote_find_tracking(), given a remote and a struct refspec with
+either src or dst filled out, will fill out the other such that the
+result is in the "fetch" specification for the remote (note that this
+evaluates patterns and returns a single result).
+
+struct branch
+-------------
+
+Note that this may end up moving to branch.h
+
+struct branch holds the configuration for a branch. It can be looked
+up with branch_get(name) for "refs/heads/{name}", or with
+branch_get(NULL) for HEAD.
+
+It contains:
+
+`name`::
+
+	The short name of the branch.
+
+`refname`::
+
+	The full path for the branch ref.
+
+`remote_name`::
+
+	The name of the remote listed in the configuration.
+
+`remote`::
+
+	The struct remote for that remote.
+
+`merge_name`::
+
+	An array of the "merge" lines in the configuration.
+
+`merge`::
+
+	An array of the struct refspecs used for the merge lines. That
+	is, merge[i]->dst is a local tracking ref which should be
+	merged into this branch by default.
+
+`merge_nr`::
+
+	The number of merge configurations
+
+branch_has_merge_config() returns true if the given branch has merge
+configuration given.
+
+Other stuff
+-----------
+
+There is other stuff in remote.h that is related, in general, to the
+process of interacting with remotes.

 run-command API
 ===============
 
-Talk about <run-command.h>, and things like:
+The run-command API offers a versatile tool to run sub-processes with
+redirected input and output as well as with a modified environment
+and an alternate current directory.
 
-* Environment the command runs with (e.g. GIT_DIR);
-* File descriptors and pipes;
-* Exit status;
+A similar API offers the capability to run a function asynchronously,
+which is primarily used to capture the output that the function
+produces in the caller in order to process it.
 
-(Hannes, Dscho, Shawn)
+
+Functions
+---------
+
+`start_command`::
+
+	Start a sub-process. Takes a pointer to a `struct child_process`
+	that specifies the details and returns pipe FDs (if requested).
+	See below for details.
+
+`finish_command`::
+
+	Wait for the completion of a sub-process that was started with
+	start_command().
+
+`run_command`::
+
+	A convenience function that encapsulates a sequence of
+	start_command() followed by finish_command(). Takes a pointer
+	to a `struct child_process` that specifies the details.
+
+`run_command_v_opt`, `run_command_v_opt_dir`, `run_command_v_opt_cd_env`::
+
+	Convenience functions that encapsulate a sequence of
+	start_command() followed by finish_command(). The argument argv
+	specifies the program and its arguments. The argument opt is zero
+	or more of the flags `RUN_COMMAND_NO_STDIN`, `RUN_GIT_CMD`, or
+	`RUN_COMMAND_STDOUT_TO_STDERR` that correspond to the members
+	.no_stdin, .git_cmd, .stdout_to_stderr of `struct child_process`.
+	The argument dir corresponds the member .dir. The argument env
+	corresponds to the member .env.
+
+`start_async`::
+
+	Run a function asynchronously. Takes a pointer to a `struct
+	async` that specifies the details and returns a pipe FD
+	from which the caller reads. See below for details.
+
+`finish_async`::
+
+	Wait for the completion of an asynchronous function that was
+	started with start_async().
+
+
+Data structures
+---------------
+
+* `struct child_process`
+
+This describes the arguments, redirections, and environment of a
+command to run in a sub-process.
+
+The caller:
+
+1. allocates and clears (memset(&chld, '0', sizeof(chld));) a
+   struct child_process variable;
+2. initializes the members;
+3. calls start_command();
+4. processes the data;
+5. closes file descriptors (if necessary; see below);
+6. calls finish_command().
+
+The .argv member is set up as an array of string pointers (NULL
+terminated), of which .argv[0] is the program name to run (usually
+without a path). If the command to run is a git command, set argv[0] to
+the command name without the 'git-' prefix and set .git_cmd = 1.
+
+The members .in, .out, .err are used to redirect stdin, stdout,
+stderr as follows:
+
+. Specify 0 to request no special redirection. No new file descriptor
+  is allocated. The child process simply inherits the channel from the
+  parent.
+
+. Specify -1 to have a pipe allocated; start_command() replaces -1
+  by the pipe FD in the following way:
+
+	.in: Returns the writable pipe end into which the caller writes;
+		the readable end of the pipe becomes the child's stdin.
+
+	.out, .err: Returns the readable pipe end from which the caller
+		reads; the writable end of the pipe end becomes child's
+		stdout/stderr.
+
+  The caller of start_command() must close the so returned FDs
+  after it has completed reading from/writing to it!
+
+. Specify a file descriptor > 0 to be used by the child:
+
+	.in: The FD must be readable; it becomes child's stdin.
+	.out: The FD must be writable; it becomes child's stdout.
+	.err > 0 is not supported.
+
+  The specified FD is closed by start_command(), even if it fails to
+  run the sub-process!
+
+. Special forms of redirection are available by setting these members
+  to 1:
+
+	.no_stdin, .no_stdout, .no_stderr: The respective channel is
+		redirected to /dev/null.
+
+	.stdout_to_stderr: stdout of the child is redirected to its
+		stderr. This happens after stderr is itself redirected.
+		So stdout will follow stderr to wherever it is
+		redirected.
+
+To modify the environment of the sub-process, specify an array of
+string pointers (NULL terminated) in .env:
+
+. If the string is of the form "VAR=value", i.e. it contains '='
+  the variable is added to the child process's environment.
+
+. If the string does not contain '=', it names an environment
+  variable that will be removed from the child process's environment.
+
+To specify a new initial working directory for the sub-process,
+specify it in the .dir member.
+
+
+* `struct async`
+
+This describes a function to run asynchronously, whose purpose is
+to produce output that the caller reads.
+
+The caller:
+
+1. allocates and clears (memset(&asy, '0', sizeof(asy));) a
+   struct async variable;
+2. initializes .proc and .data;
+3. calls start_async();
+4. processes the data by reading from the fd in .out;
+5. closes .out;
+6. calls finish_async().
+
+The function pointer in .proc has the following signature:
+
+	int proc(int fd, void *data);
+
+. fd specifies a writable file descriptor to which the function must
+  write the data that it produces. The function *must* close this
+  descriptor before it returns.
+
+. data is the value that the caller has specified in the .data member
+  of struct async.
+
+. The return value of the function is 0 on success and non-zero
+  on failure. If the function indicates failure, finish_async() will
+  report failure as well.
+
+
+There are serious restrictions on what the asynchronous function can do
+because this facility is implemented by a pipe to a forked process on
+UNIX, but by a thread in the same address space on Windows:
+
+. It cannot change the program's state (global variables, environment,
+  etc.) in a way that the caller notices; in other words, .out is the
+  only communication channel to the caller.
+
+. It must not change the program's state that the caller of the
+  facility also uses.

+
+The po/git-gui.pot file is updated by the internationalization
+coordinator from time to time.  You _could_ update it yourself, but
+translators are discouraged from doing so because we would want all
+language teams to be working off of the same version of git-gui.pot.
+
+****************************************************************
+
+This section is a note to the internationalization coordinator, and
+translators do not have to worry about it too much.
+
+The message template file po/git-gui.pot needs to be kept up to date
+relative to the software the translations apply to, and it is the
+responsibility of the internationalization coordinator.
+
+When updating po/git-gui.pot file, however, _never_ run "msgmerge -U
+po/xx.po" for individual language translations, unless you are absolutely
+sure that there is no outstanding work on translation for language xx.
+Doing so will create unnecessary merge conflicts and force needless
+re-translation on translators.  The translator however may not have access
+to the msgmerge tool, in which case the coordinator may run it for the
+translator as a service.
+
+But mistakes do happen.  Suppose a translation was based on an older
+version X, the POT file was updated at version Y and then msgmerge was run
+at version Z for the language, and the translator sent in a patch based on
+version X:
+
+         ? translated
+        /
+    ---X---Y---Z (master)
+
+The coordinator could recover from such a mistake by first applying the
+patch to X, replace the translated file in Z, and then running msgmerge
+again based on the updated POT file and commit the result.  The sequence
+would look like this:
+
+    $ git checkout X
+    $ git am -s xx.patch
+    $ git checkout master
+    $ git checkout HEAD@{1} po/xx.po
+    $ msgmerge -U po/xx.po po/git-gui.pot
+    $ git commit -c HEAD@{1} po/xx.po
+
+State in the message that the translated messages are based on a slightly
+older version, and msgmerge was run to incorporate changes to message
+templates from the updated POT file.  The result needs to be further
+translated, but at least the messages that were updated by the patch that
+were not changed by the POT update will survive the process and do not
+need to be re-translated.
