    therefore authoritative as to whether a satellite is actually

    Iridium 8 decayed.

    Sladen tweaks web page; scraper change needed.

    Further deprecate Iridium status from McCants.  Mike McCants has
    announced that he is no longer maintaining his Iridium status. The
    first use of his Iridium status will now generate a warning.  In a
    further 6 months there will be a warning on every use, and 6 months
    after that it will become fatal.

    Added Iridium status decayed ('[D]', portable status is 3 --

    Add iridium_status() format 'spacetrack'. Space Track has no idea
    whether a given satellite is in service or not, but does know
    whether it has decayed. So the status reported for a given OID is
    from Celestrak if it has it and the satellite is still in orbit.
    If a satellite is not in the Celestrak data but Space Track reports
    it as still in orbit, its status will be unknown ('[?]'), and its
    portable status will be tumbling.

    Add a hard-wired internal Iridium status table having the Space
    Track data. This is used to supplement data from other sources,
    since they typically drop a satellite once it has decayed.

    Add iridium_status() option -raw, which reports statuses
    un-supplemented by Celestrak or canned data to the extent this is
    possible. This option can be specified either command-line style
    (i.e. '-raw') or in a leading hash ref (i.e. '{ raw => 1 }'). This
    is in support of generating the above hard-wired table.

    Add script 'tools/all_iridium_classic', which queries Space Track
    for all Iridium satellites, and reports the status of the
    original-design Iridiums. This is for generating the canned status
    tables in Astro::SpaceTrack and Astro::Coord::ECI::TLE.

    Remove tests for iridium_status( 'mccants' ), since this is both
    unmaintained and deprecated.

  Fix a problem with bad Space Track queries being generated under
    certain circumstances if TLE data were being requested and class
    'tle' (rather than 'tle_latest') was being used to satisfy them. The
    problem seems to have been the leakage of extraneous data from the
    -last5 option (even if defaulted) into the REST query.

  Throttle Space Track queries to 1 every 3 seconds.  Space Track
    announced August 19 2014 that they intend to throttle queries to
    less than 20 per minute per user as of September 22 2014.  They seem
    to have jumped the gun though, since throttling seems necessary now.

  Remove all RCS-specific functionality.  This includes making -rcs do
    nothing. On August 18 2014 Space Track started returning 0 for RCS,
    instead going for "small," "medium," and "large" in a new JSON
    field.  The -rcs option is now deprecated, and being put through the
    usual deprecation cycle.

  Set default value of verify_hostname attribute to false. This is
    because Perl does not accept Mike McCants' GoDaddy certificate. The
    default can be overridden using environment variable
    SPACETRACK_VERIFY_HOSTNAME if it is defined.

  Remove all references to obsolete spacetrack() canned queries
    full_fast and geosynchronous_fast in the documentation. The queries
    themselves are long gone.

  Prepare for removal of the RCSVALUE datum in Space Track's satcat
    data, which is announced for August 18 2014.

  Add 'prompt' attribute.

  Support the various Space Track data formats. This involves providing
    a -format option, with values corresponding to the Space Track
    formats, plus 'legacy' (the default) to provide what is essentially

  Correct bug in celestrak() method, in which the Space Track REST

  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.

  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.

  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"'.

  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.

    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

  Reinstate the headings returned by -notle searches done with

  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.

  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.

  Require HTTP::Status 6.03, because I can't forebear to use the
    "teapot" status for testing purposes.

  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.)

  Correct erroneous skip() outside SKIP: block in t/query.t.

  Add JSON as dependency. It's used by the Space Track V2 interface.

  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

  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.

  Add Astro::SpaceTrack attribute verify_hostname. This controls the
    corresponding SSL option for LWP::UserAgent. By default it is true,

    unrecognized) certificates,

  Get rid of YAML::Any in favor of YAML. They are both in the same

  Use GET rather than POST to implement Astro::SpaceTrack box_score(),
    since 'POST' gives undefined errors during testing. Sometimes.

  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

    With the end of the U.S. Space Shuttle program, deprecate the
        celestrak() 'sts' catalog and the spaceflight() 'SHUTTLE'

    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.

    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.

    Redo README to be more like the CPAN-recommended organization and

    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

    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.

    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.

    Use IO::File rather than FileHandle to open files.

    Include t/critic.t (Test::Perl::Critic) and t/perlcriticrc

    When using Rod Sladen's data for Iridium status, mark all

	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.

	actually. Thanks to Andy Lester's article:
	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,
