AALLAN / Astro-FITS-Header-2.8.0 / ChangeLog 
 2003-10--21  Alasdair Allan <aa@astro.ex.ac.uk> (Version 2.8.0)
 
        * Applied patches supplied by Jim Lewis <jrl@ast.cam.ac.uk> which
          add support for MEF files. Modified documentation and shipped
          as version 2.8.0
         
2003-07-02  Alasdair Allan <aa@astro.ex.ac.uk> (Version 2.7.1)

        * Applied patches, updated documentation and shipped as 2.7.1

2003-07-02  Craig DeForest  <djerius@cfa.harvard.edu>

        * Patched to correct the column locations in the COMMENT and HEADER
          cards, and removed explicit stripping of leading blanks from COMMENT
          and HEADER card values upon input.
          
        * Fixed test errors and added more explicit tests on the parsing.    
          
2003-07-02  Alasdair Allan <aa@astro.ex.ac.uk> (Version 2.7)

        * Applied patches, updated documentation and shipped as 2.7

2003-06-27  Craig DeForest  <djerius@cfa.harvard.edu>

        * Header.pm: Added slash-based comment parsing to the tied interface

        * t/tied.t: Added test cases.
        
2003-06-23  Diab Jerius  <djerius@cfa.harvard.edu>

	* Item/Item.pm (configure): automatically sets type to COMMENT
	  when keyword is COMMENT, HISTORY, or is blank. (_stringify): comment
          keyword values/comments are in columns 9-80, unlike other cards which
          are in columns 11-80.

2003-05-27  Diab Jerius  <djerius@cfa.harvard.edu>

	* t/parse.t: added test for index() regexep functionality.

	* Header.pm: index() now handles regexps as well as exact matches.
          itembyname(), value(), comment(), replacebyname(), and removebyname()
          now call index() instead of doing the search themselves, so they
          inherit the new behavior.
	
2003-04-28  Alasdair Allan <aa@astro.ex.ac.uk> (Version 2.6.2)

        * Applied patch by Diab, shipped as 2.6.2

2003-03-28  Diab Jerius  <djerius@cfa.harvard.edu>

	* t/subhdr.t: code cleanup to avoid undefined warning

2003-03-26  Diab Jerius  <djerius@cfa.harvard.edu>

	* CFITSIO/CFITSIO.pm (writehdr):
	   if there was no END card in the existing header the initial
	   card was not written.  also, additional streamlining of code.
	
	* CFITSIO/CFITSIO.pm (configure):
	   the code assumed that there was an END card in the existing
	   header read by CFITSIO, which is not always the case.  Now
	   explictily adds one.

2003-03-13  Malcolm J. Currie <mjc@star.rl.ac.uk>

        * Item/Item.pm: Allow for a HIERARCH hierarchical header following
          a blank keyword.

2003-03-12 Alasdair Allan <aa@astro.ex.ac.uk> (Version 2.6.1)

        * t/hierarch.t: Added more test cases.

2003-03-12 Alasdair Allan <aa@astro.ex.ac.uk> (Version 2.6)

        * Minor documentation tweaks and released as Version 2.6
        
2003-03-12 Craig DeForest <deforest@boulder.swri.edu> 

        * Header.pm 
	   - FETCH: END card always returns ' ' if present, undef if not.
	   - STORE: END & SIMPLE cards are always put in the right place.
	   - STORE: Cleaned out some extra cruft in the card assignment 
	            block
	   - new:   SIMPLE & END cards are assigned automagically
	   - Documentation: several improvements.

	* Item.pm
	   - 'F' evaluates false if assigned to a card of type LOGICAL
	     (already evaluated false if assigned to a card of unknown type).
	   - END cards no longer emit warnings with 'use strict'.
	   
2003-03-11  Alasdair Allan <aa@astro.ex.ac.uk> (Version 2.5.1)

        * Minor documentation tweaks, badged as version 2.5
        
        * t/hierarch.t: Added test harness for ESO HIERARCH header keywords

2003-03-10  Tim Jenness  <timj@jach.hawaii.edu>

	* Header.pm: Add tiereturnshash, and configure it from TIEHASH
	
	* Header.pm (FETCH): Respect the new tiereturnshash method. If
	  true, will return multi-valued items as a reference to an array
	  rather than as a joined string (tied interface does not respect
	  calling context).

	* Header.pm (FETCH/STORE): Tied interface can now retrieve or set
	  the comment string associated with an item by adding '_COMMENT' to
	  the keyword.

2002-01-19  Malcolm J. Currie <mjc@star.rl.ac.uk>

        * Item/Item.pm: Added support for HIERARCH hierarchical keywords.

	  Astro::FITS::Header objects, using type HEADER

	* Header.pm (STORE): Allow an Astro::FITS::Header object to be
	  stored through the tied interface.

2002-12-03  Tim Jenness  <timj@jach.hawaii.edu>

	* Header.pm (insert{): Fix problem with tied hash when
	  doing %$tieref = %new

2002-12-02  Tim Jenness  <timj@jach.hawaii.edu>

	* NDF/NDF.pm (configure): Fix problem with SCUBA raw data. The
	  files are NDFs but are not declared as such in the type field

2002-11-27  Alasdair Allan <aa@astro.ex.ac.uk> (Version 2.4)

        * Added patch provided by Diab Jerius <djerius@cfa.harvard.edu>
          which allows you to open files in ReadOnly mode. Additionally
          it moves the module over to using the new Astro::FITS::CFITSIO 
          rather than the older CFITSIO module.

        * Minor documentation changes to reflect new versions of the
          Astro::FITS::CFITSIO library now needed by the module.

2002-06-10  Alasdair Allan <aa@astro.ex.ac.uk> 

        * Minor documentation changes, integrated patches into the main
          CVS tree, released as v2.1. The major change from v1.x is a
          much improved tied interface, see the POD for details.

        * Header.pm: FETCH and STORE convert tags to ALL UPPERCASE
          per the FITS standard.

        * Header.pm: undefine the type of newly-assigned cards in the 
          tied-hash code, so that the autotyper can figure it out.

        * Header.pm: Hash-ref passing now forces string interpretation
         
2002-05-09   Craig DeForest <deforest@boulder.swri.edu>

        * Header.pm: Added multiline support to the tied interface, using
          multiline string return -- which should preserve 0th-element 
          functionality in arithmetic expressions, as expected by legacy code.

        * t/tied.t: added multline tests.

2002-03-29   Alasdair Allan <aa@astro.ex.ac.uk> 

        * Header.pm: Added freeze() function
