Revision history for Perl extension Geo::Distance.

0.17 2011-06-28

• Fix circular package dependencies with Geo::Distance::XS (not really an issue practically, but then again it wasn't really helping).

0.16

• No changes. The 0.15 package was broken.

0.15

• Stop "Too late to run INIT block" warning (gray <gray@cpan.org>)

0.14

• Fix "splice() offset past end of array" as filed in RT 26446.

0.13

• Use Geo::Distance::XS if available. (gray <gray@cpan.org>)
• Declare Math::Trig dependency.

0.12

• Noted GIS::Distance in POD.
• Some cleanups to install process.
• Check for DBI in tests before using it.

0.11 : 2005-09-01

• Fixed some errors in the documentation.
• Added an highly accurate ellipsoid formula.
• lon_field and lat_field were not being used by closest. (D. Hageman)

0.10 : 2005-07-11

• The closest() method has a changed argument syntax and no longer supports array searches.
• The closest() method works!
• A real gcd formula (still, hsin is much better).
• Tweaked docs.
• Added some tests (yay!).

0.09 : 2005-04-01

• Modified the todo list to include ideas for future algorithms.
• Fixed the nautical mile, mile, yard, and light second units.
• Added the British spellings for kilometre, metre, and centimetre.
• Added the poppy seed, barleycorn, rod, pole, perch, chain, furlong, league, fathom, millimeter, and millimetre units.
• The totw.pl script was written by Ren and can be used to take over the world.

0.08 : 2005-03-20

• Updated the README description.
• Removed debug print()s. Eeek!

0.07 : 2005-03-16

• Intermixed documentation with code so it is easier to keep the docs up-to-date.
• OO interface only - method interface completely removed.
• By default no units are defined. Call default_units.
• Slightly more precise measurement of the base kilometer rho.
• Added "nautical mile" unit type.
• Reworked the closest() function.

0.06 : 2004-06-29

• Optional Haversine formula.
• Misc documentation tweaks.

0.05 : 2003-03-19

• Added a note in the documentation about the inaccuracies of using Math::Trig.
• The 'mile' unit was being calculated wrong which meant it was returning very inaccurate distances.
• Fixed a silly bug where a sub was being relied on that no longer exists.
• Documentation tweaks as usual.

0.04 : 2003-02-18

• Documentation revised once again.
• Added reg_unit() for adding your own unit type.
• find_closest has been overhauled:
  • Now accepts more than one field in the field=>'' parameter.
  • Will now return an array reference of distances instead of attaching the distances to the locations array ref.
  • A little more effecient.
  • Now accepts a count argument.
  • Accepts an array reference for searching. Mostly good for testing, but who knows?
• Removed geo_ portion of names for exported functions.
• Removed some of the input checking. Just not necessary.
• Enhanced tests. Now we're actually doing some real testing. Need more tests tho.

0.03 : 2003-02-15

• Documentation modified.
• Added find_closest() which accepts a $dbh for searching in an SQL database.
• distance_dirty() can now accept locations as array refs.

0.02 : 2003-02-14

• Based on a suggestion by Jack D. I migrated the code to use Math::Trig for most of the distance math.
• POD documentation written.
• Object oriented interface created.
