GIT v1.5.6 Release Notes
========================
Updates since v1.5.5
--------------------
(subsystems)
* Comes with updated gitk and git-gui.
(portability)
* git will build on AIX better than before now.
* core.ignorecase configuration variable can be used to work better on
filesystems that are not case sensitive.
* "git init" now autodetects the case sensitivity of the filesystem and
sets core.ignorecase accordingly.
* cpio is no longer used; neither "curl" binary (libcurl is still used).
(documentation)
* Many freestanding documentation pages have been converted and made
available to "git help" (aka "man git<something>") as section 7 of
the manual pages. This means bookmarks to some HTML documentation
files may need to be updated (eg "tutorial.html" became
"gittutorial.html").
(performance)
* "git clone" was rewritten in C. This will hopefully help cloning a
repository with insane number of refs.
* "git rebase --onto $there $from $branch" used to switch to the tip of
$branch only to immediately reset back to $from, smudging work tree
files unnecessarily. This has been optimized.
* Object creation codepath in "git-svn" has been optimized by enhancing
plumbing commands git-cat-file and git-hash-object.
(usability, bells and whistles)
* "git add -p" (and the "patch" subcommand of "git add -i") can choose to
apply (or not apply) mode changes independently from contents changes.
* "git bisect help" gives longer and more helpful usage information.
* "git bisect" does not use a special branch "bisect" anymore; instead, it
does its work on a detached HEAD.
* "git branch" (and "git checkout -b") can be told to set up
branch.<name>.rebase automatically, so that later you can say "git pull"
and magically cause "git pull --rebase" to happen.
* "git branch --merged" and "git branch --no-merged" can be used to list
branches that have already been merged (or not yet merged) to the
current branch.
* "git cherry-pick" and "git revert" can add a sign-off.
* "git commit" mentions the author identity when you are committing
somebody else's changes.
* "git diff/log --dirstat" output is consistent between binary and textual
changes.
* "git filter-branch" rewrites signed tags by demoting them to annotated.
* "git format-patch --no-binary" can produce a patch that lack binary
changes (i.e. cannot be used to propagate the whole changes) meant only
for reviewing.
* "git init --bare" is a synonym for "git --bare init" now.
* "git gc --auto" honors a new pre-auto-gc hook to temporarily disable it.
* "git log --pretty=tformat:<custom format>" gives a LF after each entry,
instead of giving a LF between each pair of entries which is how
"git log --pretty=format:<custom format>" works.
* "git log" and friends learned the "--graph" option to show the ancestry
graph at the left margin of the output.
* "git log" and friends can be told to use date format that is different
from the default via 'log.date' configuration variable.
* "git send-email" now can send out messages outside a git repository.
* "git send-email --compose" was made aware of rfc2047 quoting.
* "git status" can optionally include output from "git submodule
summary".
* "git svn" learned --add-author-from option to propagate the authorship
by munging the commit log message.
* new object creation and looking up in "git svn" has been optimized.
* "gitweb" can read from a system-wide configuration file.
(internal)
* "git unpack-objects" and "git receive-pack" is now more strict about
detecting breakage in the objects they receive over the wire.
pytz brings the Olson tz database into Python. This library allows accurate
and cross platform timezone calculations using Python 2.3 or higher. It also
solves the issue of ambiguous times at the end of daylight savings, which you
can read more about in the Python Library Reference (datetime.tzinfo).
Significant changes from 0.11.3 (some where already present in pkgsrc,
as we used the 0.11.4 release candidate tarballs):

form_state

failed"

too few parameters
* critical bug 1016: avoid JSFunctionSpec for better compatibility
across versions of SpiderMonkey
* critical bugs 674, 956: don't reuse pointers to SpiderMonkey objects
that may have been collected as garbage. This fix causes bug 954.

../po files

munmap() doesn't
the pkgsrc infrastructure. And the current infrastructure differs
enough from how it looked when the crosspkgtools was made, so a
somewhat different approach is needed.

changes:
-minor bugfixes
-Changes DB schema to better handle comments during
item and subscription deletion. This makes the cache
version incompatible to 1.4.15
-Update of French translation
Local change warranting nb1 is to prefix some error messages from
rrdupdate with the name of the file the error relates to, carried
over from nb1 of 1.2.27.
Update loosely OKed by martti@
The announcement of 1.3.0 outlines the changes since 1.2.27:
NEW Fast file access methods (Bernhard Fischer / Tobi Oetiker)
----------------------------
* introduced file-accessor functions rrd_read/rrd_seek/rrd_write
* implemented full mmap-based file access with madvise hints for
improved scalability, much reduced memory-footprint and much less
blocking while accessing the disk
* implemented optional full file-descriptor access instead of FILE*
access
NEW Graphing (Tobi Oetiker)
------------
* libart has been replaced by cairo/pango
* pango markup is supported (--pango-markup)
* full grid fitting
* --graph-render-mode=mono for non anti aliased graphing
* --font-render-mode=mono for non anti aliased fonts
* fonts come through fontconfig, use the Pango font nameing scheme
-> 'Times 20' ... it is not possible to use truetype fonts
directly anymore.
* Tabs are position independent.
* TRENDNAN filter that ignores NAN values while calculating the
TREND data. (Timo Stripf)
* --full-size-mode to specify the outer border of the image and not
just of the graphing canvas (Matthew Chambers)
* TEXTALIGN command to alter default text alignment behavior
* C API in-memory graphing with rrd_graph_v (Evan Miller)
* draw dashed lines in graphs (Thomas Gutzler)
* new interface graphv which returns information using the rrd_info
interface (Tobi Oetiker and Mark Plaksin)
* improved horizontal grid. Have a bit more grid lines and y-axis
labels while keeping them far enough apart to not run into each
other.
NEW Forecasting (Evan Miller)
---------------
* the new MHWPREDICT consolidation function uses a variation of the
Holt-Winters method. It is a drop-in replacement for HWPREDICT,
and is better suited for data whose seasonal variations grow or
shrink in proportion to the average.
* If you create an RRD with the new MHWPREDICT function, the
resulting rrd file will be version 0004 and can only be used in
rrdtool 1.3.
Rewrites
--------
* rrd_restore now uses libxml for parsing which makes things much
more tolerant towards xml variations. The old code could mostly
just parse the XML as it was output by rrdtool dump. See also:
the note at the bottom of this document. (by Florian octo
Forster)
* rrd_update rewritten to make it more modular. Fixed two
longstanding HW bugs in the process (Evan Miller)
Internationalization (Takao Fujiwara and Tobi Oetiker)
--------------------
* The help output by rrdtool has been internationalized. There are
no real translations included with rrdtool yet, contributions are
welcome.
* The internationalization will only be compiled if libintl and
friends are available on your system. Use the configure option
--disable-libintl if you want to disable this feature
Language Bindings
-----------------
* ruby rrd_fetch will return step as a last property -- Mike Perham
RRDtool dump / restore incompatibility
--------------------------------------
* rrdtool dump 1.3 does emit completely legal XML. Basically this
means that it contains an XML header and a DOCTYPE definition.
Unfortunately this causes older versions of rrdtool restore to be
unhappy.
* To restore a new dump with an old rrdtool restore version, either
remove the XML header and the doctype by hand (both on the first
line of the dump) or use rrdtool dump --no-header.
