          containing the location of an archive can be used anywhere

          that a repository location is (except for search).

        * Publishers are no longer required to have origins or mirrors

          so that sticky state and search order can be retained when

          installing packages from temporary sources.

        * The client API now supports the use of temporary sources of

          package during during operations.

          at the same time as other functions (such as a multi-threaded

          scenario)

        * get_pkg_categories() is now a locking operation and cannot be

          used at the same time as other functions (such as a multi-

          threaded scenario)

        * add_publisher() now permits publishers with no repository

          origins or mirrors to be added.

        * update_publisher() now permits publishers to be updated even

          if the new object has no origins or mirrors.

        * info(), get_pkg_categories(), get_pkg_list(), get_manifest(),

          plan_install(), plan_update(), plan_update_all(), and

          plan_change_varcets() now have a 'repos' parameter for

          specifying temporary package repositories for use during

          the operation.

    pkg.client.progress has changed as follows:

        * There are new methods for tracking the progress of archive

          creation: archive_set_goal(), archive_add_progress(),

          and archive_done().  See 'pydoc pkg.client.progress' for

          details.

    pkg.client.api_errors has changed as follows:

        * The PublisherOriginRequired exception class has been removed.

        * The new Exception NoPublisherRepositories was added.  It is

          raised whenever an attempt to perform a transport operation

          for a publisher with no transport configuration is made.

Version 52:

Incompatible with clients using versions 0-51:

    pkg.client.publisher.Publisher has changed as follows:

            add_cert, get_certs_by_name, get_crl, check_extensions

        * check_critical was removed.

        * verify_chain had an additional, optional, argument added to it.  The

          usages paramter defines what uses the certificate needs to allow.

          If this parameter isn't set, then it's assumed that the certificate

          should be able to be used for all known uses.

        * The following constants were added to be used as values to the usages

          parameter for verify chain.

Version 51:

Compatible with clients using versions 46-50:

    pkg.client.api.PlanDescription has changed as follows:

Version 49:

Compatible with clients using versions 46-48:

    pkg.client.api.ImageInterface has changed as follows:

        * plan_install and plan_update take an optional

          argument to reject packages in solution.

Version 48:

Compatible with clients using versions 46-47.

    pkg.client.api.ImageInterface has changed as follows:

        * The ImageInterface class constructor now accepts an

          exact_match parameter that allows consumers to control

          whether an attempt to find an image starting from the

          specified directory is made.  See 'pydoc pkg.client.api'

          for detailed usage.

        * If the exact_match parameter of the class constructor is

          False, an ImageLocationAmbiguous exception will be raised

          on Solaris if the image is not found at '/'.  Other platforms

          will continue to accept an image found at any location.

        * A new property named 'progresstracker' was added to allow

          consumers to change the ProgressTracker object used by the

          API object instance after class initialization.  See 'pydoc

          pkg.client.api' for detailed usage.

    pkg.client.api_errors has changed as follows:

        * A new ImageLocationAmbiguous exception was added.

Version 47:

Compatible with clients using version 46.

    pkg.client.api.ImageInterface has changed as follows:

        * A new function named 'update_format' has been added to allow

          clients to upgrade images in older formats to the newest one.

          By default, images rooted at '/' or that are for a zone are

          automatically upgraded to the newest format if the user of

          the client has sufficient privileges.

    pkg.client.api_errors has changed as follows:

        * A new exception named 'ImageFormatUpdateNeeded' has been added

          that may be raised by the API whenever an API operation

          requires that the image be updated to a new format before

          the operation can be performed.

Version 46:

Incompatible with clients using versions 0-45.

    pkg.client.api.ImageInterface has changed as follows:

        * The actual_cmd parameter is no longer a parameter to the

          plan_update_all function.  Instead that information is stored in the

          global_settings object.  It's used when looking for the trust anchors

          of the image from which pkg was run.

Version 45:

Compatible with clients using versions 43-44.

    pkg.client.api.ImageInterface has changed as follows:

        * A new planning function, plan_update, has been added which

          allows in place downgrades of packages.

Version 44:

Compatible with clients using version 43.

    pkg.client.api.ImageInterface has changed as follows:

        * A new property 'last_modified' was added that returns a UTC

          datetime object representing the time the image's metadata

          was last changed.

Version 43:

Incompatible with clients using versions 0-42.

    pkg.client.api.ImageInterface has changed as follows:

        * A new boot environment will now only be created if required

          for image-modifying operations (except for plan_update_all

          which continues to always create one by default).

        * The verbose parameter has been removed from the plan_*

          functions.

        * All plan_* functions now accept an additional boolean named

          'new_be' that indicates whether a new boot environment should

          be created for the operation.  This overrides the deafult

          behaviour that only creates one if needed.

    pkg.client.api.PlanDescription has changed as follows:

        * get_services(), get_varcets(), and get_actions() were added

          to allow clients more access to plan information.

        * A boolean property named new_be was added that indicates

          whether the planned operation will requires a new boot

          environment.

Version 42:

Incompatible with clients using versions 0-41.

    pkg.client.api_errors has changed as follows:

        * The MainDictParsingException class was removed

        * The BadPublisherAlias and IndexLockedException

        * The inter_certs property was renamed to intermediate_certs.

Version 41:

Compatible with clients using versions 40-41.

    Allows the client to handle signed packages.  This includes the

    addition of a large number of optional parameters to the

    client/publisher class.  It also makes changes to image creation to

    allow image properties to be set during the process.  New subclasses

    of ApiException were created to indicate different error conditions

    associated with signing failures.

Version 40:

Incompatible with clients using versions 0-39.

    The pkg.client.api ImageInterface has changed as follows:

        * The info() method no longer detects and returns multiple

          matches for patterns and instead will return all matches

          for a given pattern.

        * The ImageInterface.INFO_MULTI_MATCH property has been

          removed.

        * The PackageInfo.PREF_PUBLISHER attribute and data has been

          removed.

        * Illegal patterns will cause info() to raise an exception

          immediately.

Version 39:

Compatible with clients using versions 36-38.

    Introduces the notion of a system repository to the publisher

    heirarchy.  This specific type of repository is a subclass of

    RepositoryURI.  A few new api exceptions are added, too.

Version 38:

Compatible with clients using versions 36-37.

    The pkg.client.api now supports file-based repository access for all

    operations.  All related classes have been updated to support URIs

    that use the 'file' scheme.

Version 37:

Compatible with clients using version 36.

    The pkg.client.api ImageInterface has changed as follows:

        * Whenever an unexpected change in the state or structure

          of the image is encountered during install, remove, or

          update operations (such as a missing file, directory,

          or inability to remove an item) and it cannot be

          recovered from without user intervention, an

          ActionExecutionError exception is raised.

Version 36:

Incompatible with clients using versions 0-35.

    The interface for pkg.client.api.remote_search has changed as follows:

        * A new parameter, prune_versions, has been added which, when true,

          causes remote search to remove versions a user is unlikely to be

          interested in.

        * The return type of remote_search and local_search has changed.  Where

          the string representation used to be returned, a FMRI object is now

          returned.

Version 35:

Compatible with clients using version 34.

    The ImageInterface class has changed as follows:

        * A new method named parse_fmri_patterns has been added to

          help clients parse user input and transform any valid patterns

          into FMRI objects that can be used for comparison.  See pydoc

          'pkg.client.api' for details.

        * New constants for the parse_fmri_patterns method were added:

          MATCH_EXACT, MATCH_FMRI, and MATCH_GLOB.

Version 34:

Incompatible with clients using versions 0-33.

    The pkg.client.publisher.Publisher class has changed as follows:

        * The deprecated get_ssl_creds() and set_origin() methods

          were removed.  These functions have been marked as

          deprecated since the client API was first versioned

          and should not have been used by any clients.

Version 33:

Compatible with clients using version 32.

    The ImageInterface class has changed as follows:

        * file and directory actions will now have their mode validated

          if failure occurs during plan execution to determine if bad

          package metadata was the cause of execution failure.  In

          addition, the client API will catch failures due to corrupt

          or invalid package metadata and re-raise them as an

          InvalidPackageErrors exception.

    The pkg.client.api_errors module has changed as follows:

        * The InvalidPackageErrors exception was added.  See 'pydoc

          pkg.client.api_errors' for details.

Version 32:

Incompatible with clients using versions 0-31.

    The ImageInterface class has changed as follows:

        * The add_publisher and update_publisher methods now validate

          the image's publisher configuration against the origins of

          the publisher.  If any of the origins are found to not match,

          an UnknownRepositoryPublishers exception will be raised.

          If one of the new repository origins does not provide

          publisher configuration information or it is incomplete,

          a RepoPubConfigUnavailable exception will be raised.

    The pkg.client.api module has changed as follows:

        * A new method named image_create has been added.  See 'pydoc

          pkg.client.api' for details.

    The pkg.client.api_errors module has changed as follows:

        * UnknownRepositoryPublishers, RepoPubConfigUnavailable, and

          UnknownErrors expections have been added for use by the

          pkg.client.api.  API consumers are reminded that they should

          catch all ApiException class exceptions, although catching

          specific exception subclasses for case-by-case handling in

          addition to that is acceptable.

Version 31:

Compatible with clients using version 30.

    All image-modifying operations now lock the image for exclusive use

    by the current thread and process.  If the lock cannot be obtained,
