As no release notes were produced for v0.3.0-rc0, a description of the changes
in v0.3.0-rc0 is included here.

opkg-0.3.0-rc1
==============

- Reformat all C code so that it is easier to read (issue 119).

- Fix a few minor logic bugs.

- Tidy up `autogen.sh` and ensure it runs correctly with old versions of
  `aclocal` and non-bash shells.

- Rearrange test scripts into logical categories.

- Fix segfault when reinstalling a package with `force_reinstall` set (issue
  153).

opkg-0.3.0-rc0
==============

Dependency changes:

- opkg now depends on libarchive.

opkg:

- Rename `opkg-cl` to `opkg`.

- Add config option `autoremove` equivalent to `--autoremove` command line
  flag.

- Add config option `overwrite_no_owner` allowing un-owned files to be
  overwritten during package install (issue 99).

- Add config options `connect_timeout_ms`, `transfer_timeout_ms` and
  `follow_location` for use with CURL.

- Add command line option `--volatile-cache`.

- Add config option `no_install_recommends` and command line option
  `--no-install-recommends` to prevent the installation of packages listed as
  Recommends.

- Add command line option `--add-exclude` to add packages to an exclusion list.

- Add config option `ignore_maintainer` to silently ignore changes to files
  listed as Conffiles during a package upgrade (issue 128, part 2).

- Add config option `lock_file`. This option replaces the configure script
  argument `--with-opkglockfile`, allowing the lock file path to be specified at
  run-time.

- Add config options `info_dir` and `status_file`. Together with the config
  option `lists_dir` which existed previously, these options replace the
  configure script argument `--with-opkglibdir`, allowing the paths to the the
  data files and directories to be specified at run-time and with better
  granularity.

- Add config option `signature_type` allowing the signature verification backend
  to be selected at runtime. Both openssl and gpg support may not coexist within
  a single build of opkg.

- Add config option `check_pkg_signature` which allows individual package files
  to be signed and verified.

- Add config option `cache_local_files` to copy local files into the cache when
  downloading. If this option is not set, any URL with a `file://` is symlinked
  into the cache rather than downloaded (issue 139).

- Drop support for the old `lists_dir` config option syntax. The new syntax
  introduced in v0.2.3 must now be used.

- Add support for passing package filename arguments to `opkg info` (issue 125).

- Add support for implicit and explicit FTP-over-SSL when using the curl
  download backend.

- Add support for a https proxy using the curl download backend.

- Add support for http basic authentication when using the CURL download
  backend.

- Add support for ASCII-armored gpg signatures.

- Change the default cache directory to `/var/cache` (issue 131).

- Improve package and package feed verification.

- Improve download caching.

- Improve heuristics to determine whether an argument is a package name, remote
  URI or local path.

- Improve detection and handling of package conflicts.

- Improve handling of package flags (such as hold) and status.

- Improve proxy authentication when using the curl download backend.

- Allow interrupted downloads to be resumed when curl is enabled (issue 115).

- Only upgrade installed packages during `opkg upgrade` (issue 127).

- Correctly handle pacakges which list a virtual package in Provides, Replaces
  and Conflicts (issue 89).

- Ensure that the lock file can be created by creating the parent directory if
  it does not already exist (issue 110).

- Issue a NOTICE message not an ERROR message if files listed as Conffiles have
  been changed by the user prior to a package upgrade but the `force_maintainer`
  option has not been set (issue 128, part 1).

- Call prerm and postrm scripts on package upgrade (issue 104).

opkg-key:

- Only install `opkg-key` when gpg support is enabled.

- Add `opkg-key reset` command to remove all trusted keys.

- Add `opkg-key populate` command to populated the list of trusted keys using
  the contents of `/usr/share/opkg/keyrings`.

- Improve usage output of `opkg-key`.

update-alternatives:

- `update-alternatives` has been moved out of opkg and into opkg-utils.

Developer visible:

- Add functions `opkg_conf_get_option` and `opkg_conf_set_option`, direct
  access to `options` array is no longer allowed.

- Add documentation in `developer-doc` directory.

- Add `scripts/checkpatch.pl`, adapted from the Linux kernel. This script may be
  used to check that patches match the expected coding style and are free from
  some common mistakes.

- Remove confusing `from_upgrade` argument from `opkg_remove_pkg`.

- Drop the configure script arguments `--with-opkglockfile`, `--with-opkglibdir`
  and `--with-opkgtcdir`.

- Drop unnecessary source files under 'tests'.

- Deprecate the libopkg API defined in 'libopkg/opkg.c'. The configure script
  argument `--enable-libopkg-api` must be given to build this API.

- Improve testsuite with more tests, `make check` now runs the testsuite and
  exits non-zero if any test fails.

- Improve `autogen.sh` script for developers & maintainers, no longer runs
  configure directly. `./autogen.sh --clean` now removes all generated files
  without requiring configure to have been ran.

- Rename `conf` -> `opkg_config` to prevent global symbol clashes (issue 92).

- Allow pkg-config to be used to find the gpg-error library.

- Use libarchive to extract packages instead of hand-rolled tar, ar and gzip
  handling (adds dependency on libarchive).

- Remove libbb!

- Lots of code refactoring and minor improvements.
