libgit2 0.20.0 "anmeldung"

Apologies for the delay. This release is chunky,
but you're probably used to chunky releases by now.

Full changelog follows:

Internal changes
	+ Added support for decomposed Unicode paths in Mac OS X
	+ Added support for junctions in win32
	+ Fixed issues with HTTP redirects in the network stack
	+ Performance improvements (as always)

git2/branch.h
	+ added branch iterators as an alternative to the
	callback-based API

git2/buffer.h
	+ exported the git_buf struct to allow binary buffers
	to be passed from/to the library. This simplifies
	several APIs

git2/checkout.h
	+ implemented additional checkout options ('skip unmerged',
	'use ours' and 'use theirs')

git2/clone.h
	+ simplified the clone API
	+ added new `git_clone_into` to clone into an existing
	(empty) repository

	+ added APIs to access the raw (uncleaned) text of a commit
	message

git2/common.h
	+ added global options to set the default paths to load
	templates from

git2/config.h
	+ added multivar iterators
	+ added globbing iterator
	+ added `git_config_foreach_match` to perform operations
	on every single var in a config file

git2/filter.h
	+ added external APIs to configure and apply custom filters
	to checked out blobs

git2/index.h
	+ `git_index_read` can now force a reload of the index file
	even if it hasn't changed on-disk

git2/indexer.h
	+ improved the streaming indexer APIs

git2/merge.h
	+ added support for merge!

git2/object.h

	+ added helper APIs to work with pathspecs and match files
	in the workdir or diffs

git2/push.h
	+ added progress callbacks to push

git2/reflog.h
	+ changed reflog APIs to work on reference names instead of
	the references themselves, so they become less racy

git2/remote.h
	+ added support for setting refspecs on remotes, either at
	creation or on existing ones
	+ simplified the remotes API

git2/revwalk.h
	+ add API to simplify parents during a walk

git2/signature.h
	+ add helper to create a signature with the default values for
	a repository (i.e. the set `user.name` and `user.email` values,
	and the current time)

git2/submodules.h
	+ improve the status detection for submodules

git2/sys/
	+ exported many new internal APIs, such as pluggabe transport
	APIs

-vmg, out

libgit2 v0.19.0 "gut merge"

Minor point release! We got a lot of rather large features that we
wanted to get settled in:

- New (threadsafe) cache for objects
- Iterator for Status
- New Merge APIs
- SSH support on *NIX
- Function context on diff
- Namespaces support
- Index add/update/remove with wildcard support
- Iterator for References
- Fetch and push refspecs for Remotes
- Rename support in Status
- New 'sys/` namespace for external headers with low-level APIs

As always, this comes with hundreds of bug fixes and performance
improvements. We're faster and better than ever. And we haven't broken
many APIs this time!

Build stuff.

libgit2 v0.16.0

libgit2 v0.15.0 "Das Wunderbar Release"

I am aware the codename is not gramatically correct in any language.

Check the COPYING file for the detailed terms on libgit2's license. Check
the AUTHORS file for the full list of guilty parties.

As we slowly stabilize the API, we've dropped 1 function from the library,
and changed the signature of only 5 of them. There's of course a good
chunk of new functionality, and a thousand bug fixes.

In this release of libgit2:

	- Changed `git_blob_rawsize`: Now returns `size_t` instead of int, allowing
	files >4GB in 64 bit systems.

	- Removed `git_commit_message_short`: Please use `git_commit_message`
	to get the full message and decide which is the "short view" according
	to your needs (first line, first 80 chars...)

	- Added `git_commit_message_encoding`: Returns the encoding field of a commit
	message, if it exists.

	- Changed `git_commit_create`, `git_commit_create_v`: New argument `encoding`, which
	adds a encoding field to the generated commit object.

	- Added `git_config_find_system`: Returns the path to the system's global config
	file (according to the Core Git standards).

	- Changed `git_config_get_XX`, `git_config_set_XX`: the `long` and `int` types have
	been replaced by `int64` and `int32` respectively, to make their meaning more
	obvious.

	- Added `git_indexer`: An interface to index Git Packfiles has been added in the
	`git2/indexer.h` header.

	- Changed `git_reflog_entry_XX`: Reflog entries are now returned as `git_oid *` objects
	instead of hexadecimal OIDs.

	- Added `git_remote`: More fetch functionality has been added to the `git2/remote.h`
	functionality. Local, Smart HTTP and Git protocols are now supported.

	- Added `git_repository_head`: Returns the HEAD of the repository.

	- Added `git_repository_config_autoload`: Opens the configuration file of a repository,
	including the user's and the system's global config files, if they can be found.

	- Changed `git_signature_now`: Now returns an error code; the signature is stored by
	reference.

libgit2 v0.14.0, "watermelon wheat"

This a very packed minor release. The usual guilty parties have been
working harder than usual during the holidays -- thanks to everyone
involved!

As always, the updated API docs can be found at:

	http://libgit2.github.com/libgit2/

NEW FEATURES:

	- New OS abstraction layer. This should make all POSIX calls much
	more reliable under Windows.

	- Much faster writes of simple objects (commits, tags, trees) to the
	ODB via in-memory buffering and direct writes, instead of streaming.

	- Unified & simplified API for object creation. All the `create`
	methods now take Objects instead of OIDs to ensure that corrupted
	(dangling) objects cannot be created on the repository.

	- Fully Git-compilant reference renaming (finally!), with
	the already existing `git_reference_rename`.

	- Deletion of config keys with `git_config_delete`

	- Greatly improved index performance when adding new entries

	- Reflog support with the `git_reflog` API

	- Remotes support with the `git_remote` API

	- First parts of the Networking API, including refspecs and
	the transport abstraction layer. (Note that there are no actual
	transports implemented yet)

	- Status support with the `git_status_foreach` and `git_status_file`
	functions.

	- Tons of bugfixes, including the outstanding bug libgit2#127 (wrong sort
	ordering when querying tree entries).

KNOWN ISSUES:

	- The reference renaming code leaks memory. This is being worked on
	as part of a reference handling overhaul.

	- The tree-from-index builder has abysmal performance because it
	doesn't handle the Treecache extension yet. This is also being
	worked on.

libgit2 v0.13.0 "Watermelon Wheat"

On this rascalicious minor release of libgit2:

- We've dropped support for Waf. All the build process is now managed
through CMake for all platforms.

- We've removed the custom backends from the repository. You can now
find a collection of Custom backends on their own repo, under the
libgit2 org. Including MySQL and Memcache backends, courtesy of the
beardful Brian Lopez.

- We are rocking a new documentation system, Docurium, courtesy of the
insightful Scott Chacon. Check out the details for each single method
in our external API and the way they've evolved through the history
of the library:

	http://libgit2.github.com/libgit2/

This will certainly come in handy if you are developing bindings for
the library.

- You can now check the linked version of the library from your
application or bindings, using `git_libgit2_version`.

- We have a gazillion new features, courtesy of our invaluable
collaborators, including:

	* Support for Config files!
	* Support for prefix-only reads on the ODB
	* Repository discovery
	* Support for the Unmerged Entries index extension
	* Better Windows support
	* 30.000 bug fixes (actual number may be lower)

Thanks as always to everyone who makes this project possible.

Here's the full list of all external API changes:

- git_index_open_bare
- git_index_open_inrepo
- git_odb_backend_sqlite
- git_oid_mkraw
- git_oid_mkstr
- git_reference_listcb
- git_repository_workdir

libgit2 v0.12.0 "absolutely no reason"

Hey, welcome to yet another minor libgit2 release. Sorry for the delay from
the last one. As you'll see the changelog is quite extensive -- hopefully from
now on we'll stick to more frequent minor releases.

Together with the usual bugfixes, here's a list of the new key features:

* Distfiles

	This version comes with proper distfiles as requested in libgit2#131. These are
	available in the Downloads section of the GitHub project.

* Error handling

	A new error handling API has been implemented that allows the library to
	return detailed error messages together with the generic error codes. We
	hope this will be a great when wrapping and integrating the library

	New external method to get the last detailed error message:

		+ git_lasterror(void)

	The old `git_strerror` still exists, but will be deprecated in the future
	as soon as every method in the library returns a valid error message.

	The task of writing error messages for every method is quite daunting.
	We appreciate pull requests with more error messages. Check the new error
	handling documentation in the following commit:

	libgit2@fa59f18

* Redis backend

	We now have a Redis backend courtesy of Dmitry Kovega. Just like the
	SQLite backend, this allows the library to store Git objects in a Redis
	key-value store.

	The backend requires the `hiredis` library. Use `--with-redis` when
	building libgit2 to enable building the backend if `hiredis` is available.

* Commits

	New methods to access tree and parent data as a raw OID value
	instead of forcing a repository lookup

		+ git_commit_tree_oid(git_commit *commit)
		+ git_commit_parent_oid(git_commit *commit, unsigned int n)

* Index

	The `git_index_add` method has been split into 4 different calls
	which allow for appending and replacing in-memory entries and on-disk
	files to the index.

		+ git_index_add(git_index *index, const char *path, int stage)
		+ git_index_add2(git_index *index, const git_index_entry *source_entry)
		+ git_index_append(git_index *index, const char *path, int stage)
		+ git_index_append2(git_index *index, const git_index_entry *source_entry)

	Index entries can now also be efficiently removed from the index:

		+ git_index_remove(git_index *index, int position)

* References

	Methods to force the creation and renaming of references, even if those already
	exist on the repository.

		+ git_reference_create_symbolic_f(git_reference **ref_out, git_repository *repo,
				const char *name, const char *target)
		+ git_reference_create_oid_f(git_reference **ref_out, git_repository *repo,
				const char *name, const git_oid *id)
		+ git_reference_rename_f(git_reference *ref, const char *new_name)

* Repository

	New auxiliary methods with repository information

		+ git_repository_is_empty(git_repository *repo)
		+ git_repository_path(git_repository *repo)
		+ git_repository_workdir(git_repository *repo)

* Signatures

	New method to create a signature with the current date/time

		+ git_signature_now(const char *name, const char *email)

* Tags

	Several wrappers to automate tag creation.

		+ git_tag_create_frombuffer(git_oid *oid, git_repository *repo,
				const char *buffer)
		+ git_tag_create_f(git_oid *oid, git_repository *repo,
				const char *tag_name, const git_oid *target,
				git_otype target_type, const git_signature *tagger,
				const char *message);
		+ git_tag_create_fo(git_oid *oid, git_repository *repo,
				const char *tag_name, const git_object *target,
				const git_signature *tagger, const char *message)

	New functionality to delete and list tags in a repository without
	having to resort to the `references` API.

		+ git_tag_delete(git_repository *repo, const char *tag_name)

		+ git_tag_list(git_strarray *tag_names, git_repository *repo)

* Trees

	All instances of `git_tree_entry` are now returned and handled
	as constant, to remind the user that these opaque types are not
	supposed to be manually free'd.

	The `git_tree_entry_2object` method now takes a `git_repository`
	argument which defines in which repository the resolved object
	should be looked up. (It is expected to be the same repository
	that contains the parent `git_tree` for the entry).

		+ git_tree_entry_2object(git_object **object_out, git_repository *repo,
				const git_tree_entry *entry)

	New opaque type `git_treebuilder` with functionality to create and
	write trees on memory

		+ git_treebuilder_create(git_treebuilder **builder_p, const git_tree *source)
		+ git_treebuilder_clear(git_treebuilder *bld)
		+ git_treebuilder_free(git_treebuilder *bld)
		+ git_treebuilder_get(git_treebuilder *bld, const char *filename)
		+ git_treebuilder_insert(git_tree_entry **entry_out, git_treebuilder *bld,
				const char *filename, const git_oid *id, unsigned int attributes)
		+ git_treebuilder_remove(git_treebuilder *bld, const char *filename)
		+ git_treebuilder_filter(git_treebuilder *bld,
				int (*filter)(const git_tree_entry *, void *), void *payload)
		+ git_treebuilder_write(git_oid *oid, git_repository *repo, git_treebuilder *bld)

	New method to write an index file as a tree to the ODB.

		+ git_tree_create_fromindex(git_oid *oid, git_index *index)

Thanks to the usual guility parties that make this this happen, to
all the new contributors who are starting to submit pull requests, and
to the bindings developers who have to keep up with our shit.
