libgit2 v0.15.0 "Das Wunderbar Release"

2011-10-05T20:48:36Z

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been replaced by `int64` and `int32` respectively, to make their meaning more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"

2011-07-14T01:26:08Z

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 #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"

2011-06-19T10:51:09Z

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

libgit2 v0.12.0 "absolutely no reason"

2011-05-10T21:47:51Z

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)
```

2011-03-28T19:35:27Z

Apologies for the massive changes in the external API (that's my fault),
and for the terrible codename for this release (that's @tclem's fault).

commit at 72a3fe4.

Major new features in this release:

- Real caching and refcounting on parsed objects
- Real caching and refcounting on objects read from the ODB
- Streaming writes & reads from the ODB
- Single-method writes for all object types
- The external API is now partially thread-safe
- Improved reference handling
- New method to list references
- ZLib is now built-in
- Improvements to the Revision Walker
- Tons of bug fixes

Thanks to all the contributors who make this possible.

v0.10.0: libgit2 version 0.10.0, "very disco"

2011-03-14T22:02:29Z

A version so awesome that needs 2 version bumps AND a codename.

Major features:

- New internal garbage collection (harder)
- Pack backend rewritten from scratch (better)
- Revision walker rewritten from scratch (faster)
- New object interdependency system (stronger)
- Unique OID shortener
- Reference listing

In honor of one heck of a music album, released ten years ago,
yesterday.

v0.8.0: Bump the version number to 0.8.0

2011-03-03T18:23:53Z

Yes, these are some seriously massive changes to the external API. We
are breaking stuff.

v0.3.0: Add proper version management

2011-02-07T08:35:58Z

We now have proper sonames in Mac OS X and Linux, proper versioning on
the pkg-config file and proper DLL naming in Windows.

The version of the library is defined exclusively in 'src/git2.h'; the build scripts
read it from there automatically.
