  No changes since 0.069_03.

0.069_03	2012-12-17	T. R. Wyant
  Add notification that I plan to change the way Makefile.PL and
    Build.PL decide whether to install executables July 1 2013.

0.069_02	2012-12-15	T. R. Wyant
  Add method favorite() to access the Space Track 'Favorites'
    functionality. This only works for the Space Track version 2
    interface.
  Add to the spacetrack() method for version 2 of the interface those
    bulk data catalogs which are represented by 'Global Favorites'.
  Add 'YUN' (Yunsong, DPRK) to hard-coded list of launch sites returned
    by the Space Track REST interface.

0.069_01	2012-12-02	T. R. Wyant
  Re-instate the use of hour, minute, and second spacifications in
    -start_epoch and -end_epoch for the Space Track REST interface.
  Go back to using OID ranges in the retrieve() method if the Space
    Track REST interface is being used.
  Document environment varoables SPACETRACK_REST_RANGE_OPERATOR and
    SPACETRACK_REST_FRACTIONAL_DATE, so users can get themselves going
    again if there are further glitches in the related functionality.
  Add method celestrak_supplemental() to retrieve the supplemental TLEs
    not derived from SpaceTrack.
  Correct bug in celestrak() method, in which the Space Track REST
    options were being parsed when they should not have been. This was
    really two bugs: use of get() rather than getv() to check the Space
    Track version, and failure to check the 'direct' attribute.

0.069		2012-11-09	T. R. Wyant
  Do not pass the time portion of a date/time query to the Space Track
    REST interface, since it seems not to handle it (though I thought it
    did at one time).

0.068		2012-10-26	T. R. Wyant
  Retract use of ranges when fetching from Space Track REST interface by
    OID, since it appears this is not stable yet.

0.067		2012-10-25	T. R. Wyant
  Document a new Celestrak "direct-fetch only" data set, 2012-044, which
    represents the explosion of a Breeze-M upper stage (2012-044C) on
    October 16 2012.
  Re-instate the use of ranges when fetching a number of OIDs via the
    Space Track REST interface, since they are supported now.
  Fix bug that allowed Kelso's Iridium status to "bleed through" into
    the McCants status data.

0.066		2012-10-15	T. R. Wyant
  Add methods country_names() and launch_sites(), to return the
    expansions of the relevant abbreviations in either tabular form or
    JSON. Under space_track_version == 2, launch_sites() is hard-coded,
    since this information is not available under the REST interface.
  The box_score() method now takes option -json, to return the data in
    JSON format. If space_track_version == 1, the JSON is made up from
    the tabular data.

0.065		2012-10-09	T. R. Wyant
  Retract the merging of names from observing lists (in celestrak() and
    file()) in REST queries, since we can now get them direct from the
    REST interface in all cases. This was introduced in 0.062, with the
    statement that it was temporary.
  Don't use OID ranges in REST queries, since they do not work in
    combination with comma-separated lists.
  Change the size of a retrieve() batch to 200, since larger queries
    seem to be faster.
  Add method update(). This works with the REST interface only, and
    therefore ignores the space_track_version setting. It takes as its
    argument the name of a JSON file containing TLE data, and updates it
    using '/FILE/>...'. The return is whatever format you want.
  Make the REST options work with the spacetrack() method.
  Enable the -sort and -descending options on REST queries. These were
    previously hard-wired (to -sort epoch -descending) because of
    problems early in the beta, which seem to be solved.
  Recode the REST versions of spacetrack( 'full' ) and spacetrack(
    'geosynchronous' ) to go through class satcat to eliminate bodies
    that have decayed. Provide 'full_fast' and 'geosynchronous_fast' for
    those who like to live dangerously. The last two are considered
    experimental, and may be retracted.
  Get the object name from field OBJECT_NAME when using the Space Track
    REST interface, in all cases.

0.064_02	2012-10-02	T. R. Wyant
  Make use of the new TLE_LINE0 field in the tle and tle_latest classes
    to have the version 2 retrieve() method return common names.
  INCOMPATIBLE CHANGE: In JSON output, the object name is now in field
    OBJECT_NAME. Previously there was no object name in the tle data,
    and I was hammering it into field SATNAME, since that is where it
    was in the satcat data.
  Give spacetrack_query_v2() the ability to add header pragmas if it
    discovers it was called from outside the Astro::SpaceTrack name
    space.  It adds 'spacetrack-type = modeldef' if the query is
    'basicspacedata => "modeldef"', and 'spacetrack-type = orbit' if the
    query is 'basicspacedata => "query", class => 'tle'" or '... class
    => "tle_latest"'.

0.064_01	2012-09-30	T. R. Wyant
  Change attribute verify_hostname's default value to true again, since
    Space Track says they have their act together.
  Correct documented name of class used to retrieve current TLE data
    using the Space Track REST interface. It's 'tle_latest', not
    'tle_current'.

0.064		2012-09-05	T. R. Wyant
  Add REST support for as many of the spacetrack() bulk data sets as I
    can figure out. The analysis is in Astro::SpaceTrack::BulkData.
  The default -status for a REST query is now 'onorbit'. The default for
    version 1 queries remains 'all'.
  Space Track REST queries now use the 'tle_latest' class unless
    historical data are needed, as indicated by use of -start_epoch,
    -end_epoch, -since_file, or some -status other than 'onorbit'.
  Add 'time' and 'olist' meta-commands to the shell() method. The latter
    is experimental, and may go away.
  Eliminate superfluous REST queries issued by search_name() and
    search_oid(). These were introduced in 0.060_07.
  Suppress appending of '--rcs' to the common name by the REST interface
    when RCSVALUE is null.
  Fix problem with merging names from an observing list into JSON REST
    data.

0.063		2012-08-29	T. R. Wyant
  Imposed Space Track REST cookie expiration of an hour. The cookie
    appears to come with no expiration, but the docs say it's only good
    for about 2 hours.
  Followed change to representation if International Launch Designator
    (INTLDES) in Space Track REST class tle. It was yyyy-lllp, but is
    now yylllp, just like Space Track version 1.

0.062		2012-08-25	T. R. Wyant
  Fix the joining of JSON data when one of the lists is empty.
  Have the celestrak() and file() methods supply common names from their
    sources if the with_name attribute is true and the
    space_track_version attribute is 2. This functionality will be
    retracted when (and if) the Space Track REST interface becomes
    capable of supplying NASA-format TLEs.
  Document the fact that Space Track has deprecated bulk data downloads,
    and plans to remove them in October 2012. This will break the
    spacetrack() method.
  Use more recent datas for launch date and historical query tests in
    t/query.t, since it seems that Space Track purged the version 2 TLE
    database on August 24 2012.

0.061		2012-08-15	T. R. Wyant
  Reinstate the headings returned by -notle searches done with
    space_track_version set to 1. These were lost in version 0.060_09.
  When the space_track_version attribute is 2, implement the -exclude
    search option in terms of the OBJECT_TYPE field rather than by
    simulating the version 1 exclusion rules in the client. This can
    mean different search results depending on the interface used (e.g.
    Westford needles are debris under v1, but payload under v2), but
    since the change seems to be deliberate on the part of Space Track,
    I am following it.

0.060_12	2012-08-07	T. R. Wyant
  Turn on autoflush in t/query.t to try to prevent overwriting of
    prompt.

0.060_11	2012-07-31	T. R. Wyant
  Have the REST version of retrieve() issue multiple queries if the
    number of OIDs is over 50.
  Add the ability to handle OID ranges to the REST versions of
    retrieve() and search_oid().
  Have the output of names( 'spacetrack' ) depend on the value of the
    space_track_version attribute.
  Have the shell() method extract redirections from the command line
    before un-quoting and un-escaping the data, so that we have a way to
    force something that looks like a redirection to be taken as an
    argument.


0.060_10	2012-07-27	T. R. Wyant
  Add ':' to the list of 'safe' characters when URI-escaping arguments
    to the Space Track REST interface. Percent-encoded colons seemed to
    stop working some time between 13:15 and 19:15 GMT on July 27 2012.
    Un-encoded colons go through fine.
  Accept ':' as well as '/' as punctuation between username and password
    in environment variable SPACETRACK_USER.
  Have t/query.t try to load Term::ReadKey. If successful, it uses it to
    turn off password echoing. If not successful, it adds '(ECHOED)' to
    the prompt.

0.060_09	2012-07-24	T. R. Wyant
  Fix problem associating RCS data with TLEs when using version 1 of the
    Space Track interface and the OID in the search results is less than
    five digits.
  Change default value of verify_hostname attribute to false. And about
    time.
  Add attribute 'pretty' to reqest that JSON text (and potentially
    others) be pretty-formatted.

0.060_08	2012-07-23	T. R. Wyant
  Expose the name of the Space Track session cookie as an attribute.
    This is one of those attributes which have distinct values for each
    value of space_track_version.
  Have the parser for the retrieve() -start_epoch and -end_epoch options
    accept time of day as well as just date. Pass time of day to the
    server when using the Space Track REST interface.

0.060_07	2012-07-21	T. R. Wyant
  Further deprecate celestrak( 'sts' ) and spaceflight( 'shuttle' ) so
    that they give a warning every time they are used. I jumped the gun
    a bit, but this is a development release.
  If both -json and -rcs are in effect, return RCSSOURCE as well as
    RCSVALUE.
  Have the attribute_names() method take account of the fact that the
    'cookie_expires' attribute does not exist if the space_track_version
    attribute is set to 2.
  Ignore the -sort and -descending retrieve() options when using the
    Space Track REST interface. As things now stand, I have to force the
    equivalent of -sort=epoch -descending when retrieve()-ing multiple
    OIDs to get sane results.
  Add a -json retrieve() option, valid only if the REST interface is in
    use. This also works with celestrak() and file() if the
    space_track_version attribute is 2, but with celestrak() the usual
    restrictions on retrieve() options apply.
  Retrieve TLEs for multiple OIDs in a single call to the Space Track
    REST interface.

0.060_06	2012-07-12	T. R. Wyant
  Require HTTP::Status 6.03, because I can't forebear to use the
    "teapot" status for testing purposes.

0.060_05	2012-07-11	T. R. Wyant
  Expose spacetrack_query_v2(), which is our lowest-level interface to
    Space Track version 2.
  Use JSON rather than YAML for serialization in (e.g.)
    t/spacetrack_request.t, since the former is now a requirement, but
    the latter never was.
  Bit-mapped the unsupported dump_headers attribute.
  Eliminated the unsupported debug_url attribute.

0.060_04	2012-07-06	T. R. Wyant
  Implement epoch selection of TLEs via the Space Track REST interface.
  Run all the Space Track REST arguments through URI::Escape, which has
    been added as a requirement.
  Try to detect Space Track login failure due to a host verification
    problem, and recommend setting the verify_hostname attribute false.

0.060_03	2012-07-02	T. R. Wyant
  Correct erroneous skip() outside SKIP: block in t/query.t.

0.060_02	2012-07-02	T. R. Wyant
  Add JSON as dependency. It's used by the Space Track V2 interface.

0.060_01	2012-07-01	T. R. Wyant
  Provide access to Space Track v2 REST interface, which is currently in
    beta. This involves adding attribute space_track_version. Attributes
    cookie_expires, domain_space_track, and session_cookie now have
    separate values for each possible value of space_track_version.
    Due to limitations of the version 2 interface, bulk data downloads
    throw an exception, and the with_name attribute is ignored by
    retrieve(),
  Add a logout() method, which deletes all the session cookies. I
    considered having it only delete the session cookie for the current
    space_track_version, but decided that this was too confusing.
  Fix problem with Astro::SpaceTrack file() method passing its options
    hash to the retrieve() method as an OID. This was probably
    introduced in version 0.020.
  Bump Test::More requirement from 0.88 to 0.96 so I can do subtests.
  Add method content_interface, which returns the version of the Space
    Track interface use to fetch the data. If Space Track was not
    involved, returns undef.
  Add verify_hostname option to SpaceTrackTk settings window. Add
    'Settings ...' button to login screen.

0.060		2012-06-09	T. R. Wyant
  Add Astro::SpaceTrack attribute verify_hostname. This controls the
    corresponding SSL option for LWP::UserAgent. By default it is true,
    but can be made false to deal with invalid (or at least
    unrecognized) certificates,

0.059		2012-06-02	T. R. Wyant
  Get rid of YAML::Any in favor of YAML. They are both in the same
    distro, and YAML does not suffer from deprecation warnings.

0.058		2012-02-22	T. R. Wyant
  Use GET rather than POST to implement Astro::SpaceTrack box_score(),
    since 'POST' gives undefined errors during testing. Sometimes.

0.057		2012-01-22	T. R. Wyant
  Further deprecate the Astro::SpaceTrack celestrak( 'sts' ) and
    spaceflight( 'shuttle' ) functionality by having them display a
    warning on first use. The next step (warning on every use) will be
    taken on or after July 22 2012.
  Expand ranges passed to the search_oid() method, since the Space Track
    API does not support them.
  Bring Changes file into compliance with Test::CPAN::Changes. Add
    author test xt/author/changes.t to be sure it remains so.

0.056		2011-12-18	T. R. Wyant
    Validate search options -exclude and -status even if they come in
	through the API in a hash, not just if they come in as
	command-line-style arguments.

0.055		2011-11-28	T. R. Wyant
    Update copy of GNU GPL in LICENSES/Copying to have current FSF
        address.
    Require Test::More 0.88 for testing.
    Remove the Space Shuttle option from the SpaceTrackTk 'Human Space
        Flight' dialog.

0.054		2011-07-21	T. R. Wyant
    With the end of the U.S. Space Shuttle program, deprecate the
        celestrak() 'sts' catalog and the spaceflight() 'SHUTTLE'
	argument. The latter now does nothing, so we will not get 404
	errors when the web page goes away.

0.053		2011-07-04	T. R. Wyant
    Correct the URL for Mike McCants' Iridium status web page.

0.052		2011-04-12	T. R. Wyant
    Add attribute scheme_space_track_attribute, defaulting to 'https'.
	Also added LWP::Protocol::https as a dependency. Both in
	response to USSTRATCOM going to a secure server some time in the
	last 24 hours. Thanks to Thomas Wehr for diagnosing this, and
	reporting both problem and solution.

0.051		2011-02-10	T. R. Wyant
    Correct check for non-existent attribute in Astro::SpaceTrack getv()
	method.
    Update documentation of Mike McCants' status codes.

0.050		2010-10-12	T. R. Wyant
    Remove the diagnostics inserted in 0.049_01.

0.049_01	2010-10-02	T. R. Wyant
    _Really_ properly default the 'sort' retrieve option. Honest.
    More voluminous diagnostics in t/query.t for spacetrack() CPAN
        testers failures in 0.049.

0.049		2010-09-26	T. R. Wyant
    Properly default the 'sort' retrieve option when options are
	specified as a hash reference rather than as command-style
	options.

0.048		2010-09-18	T. R. Wyant
    Correct skip counts in t/query.t. Add xt/author/query_skip_sites.t
        to try to ensure they don't get out of whack again.

0.047		2010-09-17	T. R. Wyant
    Add Astro::SpaceTrack method getv() to do what get() should have
	done -- return the attribute value without wrapping it in an
	HTTP::Response object.
    Add the -rcs option to the Astro::SpaceTrack search_*() methods, to
	request that the radar cross-section data be hacked into the
	name line of the TLE, in the same way that the effective date is
	for Human Space Flight TLEs.
    Complete rewrite of SpaceTrackTk, to incorporate all (or at least
	the great majority) of the modern bells and whistles.
    Update banner text to try to make clear that only Space Track
	requires registration before use.
    Update documentation to show all content_types.
    Drop requirement for Params::Util.
    Require Perl 5.6.2, since that is the earliest version I have  a
	prayer of actually supporting.
    Move author tests from xt/ to xt/author.

0.046		2010-03-28	T. R. Wyant
    Add methods search_decay(), search_oid(), and box_score().
    Replace '' with undef in the array returned by the search_* methods
	in list context. The HTTP::Response returned by these methods
	is unchanged.

0.045_01	2010-03-22	T. R. Wyant
    Add -notle option to the search_* methods. This causes them to
        return the results of the search, rather than going on to
	retrieve the TLEs. The results are one entry per line with
	fields tab-delimited, and whitespace compressed and trimmed
	front and back. No change in the list returned in list context,
	except for the whitespace massaging.

0.045		2010-03-01	T. R. Wyant
    Redo README to be more like the CPAN-recommended organization and
        contents.

0.044_01	2010-02-22	T. R. Wyant
    Move developer tests to xt/, and run them with Build target
        authortest, supplied by inc/My/Module/Build.pm. The author tests
        are not supported with make.
    Split off the data acquisition tests from t/basic.t into t/query.t.
        Both these, plus xt/celestrak_datasets.t and xt/executable.t
        were rewritten to use Test::More 0.40, which is now required for
        building (or at least testing!) the package.
    Make some of the tests in t/query.t TODO, since they require
        historical data, and Space Track seems to have had a database
        problem.
    Convert all code to the CPAN-recommended license scheme. Update all
        copyrights while I was at it.
    Make the version of all production code in the package (including
        Astro::SpaceTrack::Parser, which was previously unversioned) to
        be the same as the package itself.
    Update the counts for the various debris events that are documented
        in Astro::SpaceTrack.

0.044		2009-09-03	T. R. Wyant
    Get rid of YAML dump in Build.PL, that was carelessly left in
        after I convinced Module::Build not to insert itself as
        required for configuration (because I also distribute
        Makefile.PL

0.043		2009-09-01	T. R. Wyant
    Add the retrieve() options to search_id(), which never had them
	before.
    Test the request arguments generated for each of the Space Track
	methods, to try to make sure we do not lose them again.

0.042		2009-08-30	T. R. Wyant
    Add the retrieve() options back to Space Track search requests.
	These were lost in version 0.035 when Perl::Critic compliance
	was added. Thanks to Thomas Wehr for finding this.

0.041		2009-08-18	T. R. Wyant
    Add ability to parse effective date from NASA Human Spaceflight.
        Add this to line 0 of the NASA TLE as --effective date_text.
        This is optional, and done only if '-effective' is passed
	to the spaceflight() method. The reason this was done was to
	support the 'effective' attribute of Astro::Coord::ECI::TLE.
	Thanks to Thomas Wehr for reporting the problem this addresses,
	and T. S. Kelso for explaining what was needed to fix it.

0.040		2009-04-22	T. R. Wyant
    Suppress undefined value warnings generated when username and
	password are set via 'set' rather than via the relevant
	environment variables when the object is instantiated.

0.039		2009-03-09	T. R. Wyant
    Document Celestrak 'direct-fetch-only' data sets
	'cosmos-2251-debris' and 'iridium-33-debris'.
    Fix 'spaceflight' retrieval test, which failed if all NASA's
	orbital elements had epochs in the future.

0.038		2009-02-13	T. R. Wyant
    Correct parsing of Rod Sladen's Iridium status web page to
	track the way he recorded the demise of Iridium 33.
    Correct '## no critic' entries to put parens around names of
	policies to be disabled.
    Update t/perlcriticrc.

0.037		2009-01-01	T. R. Wyant
    Retract copyright year test in t/basic.t
    Update version and copyright in Astro::SpaceTrack. No other
	changes.

0.036		2008-12-31	T. R. Wyant
    Revise Celestrak retrieval status check to get (hopefully) a
	better indication of what happened when retrieval failed.
    Add dependency on Params::Util 0.012; use _INSTANCE from that
	module, rather than eval{$thing->isa($class)}.
    Use IO::File rather than FileHandle to open files.
    Include t/critic.t (Test::Perl::Critic) and t/perlcriticrc
	in distribution, but only test if environment variable
	DEVELOPER_TEST is true.
    Remove '## no critic' flags in code, which are not needed at
	the desired severity (--stern) if run with the distributed
	t/perlcriticrc file.

0.035		2008-12-23	T. R. Wyant
    When using Rod Sladen's data for Iridium status, mark all
	'failed' iridiums as tumbling, whether or not there is
	a 't' next to their numbers. This makes the Sladen data
	consistent with Mike McCants' (as of 22-Dec-2008) and
	T. S. Kelso's.
    Bring all code up to perlcritic --stern (sometimes by
	declaring exceptions)
    Restructure Build.PL and Makefile.PL to better accomodate
	the installed version of Module::Build or
	ExtUtils::MakeMaker.
    Add minimum Perl version to 'requires' key in Build.PL.
	Not done in Makefile.PL because ExtUtils::MakeMaker
	does not seem to like it.
    Include t/celestrak_datasets.t, t/executable.t,
	t/iridium_status.t, t/manifest.t, and
	t/spacetrack_datasets.t in distribution, but only run
	them if environment variable DEVELOPER_TEST is true.
    Move changes from Astro::SpaceTrack pod to Changes file.
    t/basic.t will now display net errors where generated and
	(hopefully) appropriate.

0.034		2008-11-24	T. R. Wyant
    Eliminate use of UNIVERSAL::isa as a function.
    Add 'Pragma spacetrack-source = ' header to all methods
	that return TLEs or Iridium status, saying where
	the data came from.
    Add content_source() method to access spacetrack-source
	header.
    Try for less bad test coverage. Good coverage awaits a
	rewrite of the shell() method.

0.033		2008-09-30	T. R. Wyant
    Fix Build.PL -y (and -n)
    Add iridium_status('sladen') to scrape Rod Sladen's Iridium
	Constallation Status web page.
    Add attribute 'url_iridium_status_sladen'.

0.032		2008-07-06	T. R. Wyant
    More graceful failure when unable to parse Space Track data.

0.031		2007-12-21	T. R. Wyant
    Fix embedded modifier bug, exposed by the fixing of the
	corresponding Perl bug (id=22354) in 5.10.0 -- or 5.9.0
	actually. Thanks to Andy Lester's article:
	http://perlbuzz.com/mechanix/2007/12/code-broken-by-regex-fixes-in.html
	which tipped me off before I had to discover the problem
	for myself.
    Fixed dependencies in Makefile.PL and Build.PL.
    Went back to prompting for executables in Makefile.PL and
	Build.PL, as a way to handle apparant ActiveState build
	failure because both they and I were running pl2bat.bat.
    Enhance ExtUtils::MakeMaker version detection in Makefile.PL,
	since ActiveState is apparantly deploying a Perl 5.10
	with a development version of that module.
