+Version 1.0.1; March 24 2006
+
+ The changes to PyFITS were primarily to improve the docstrings and to
+ reclassify some public functions and variables as private. Readgeis
+ and fitsdiff which were distributed with PyFITS in previous releases
+ were moved to pytools. This release of PyFITS is v1.0.1. The next
+ release of PyFITS will support both numarray and numpy (and will be
+ available separately from stsci_python, as are all the python packages
+ contained within stsci_python). An alpha release for PyFITS numpy
+ support will be made around the time of this stsci_python release.
+ * Updated docstrings for public functions.
+ * Made some previously public functions private.
+ _________________________________________________________________
+
+Version 1.0; November 1 2005
+
+ Major Changes since v0.9.6:
+
+ * Added support for the HEIRARCH convention
+ * Added support for iteration and slicing for HDU lists
+ * PyFITS now uses the standard setup.py installation script
+ * Add utility functions at the module level, they include:
+
+ * getheader
+ * getdata
+ * getval
+ * writeto
+ * append
+ * update
+ * info
+
+ Minor changes since v0.9.6:
+
+ * Fix a bug to make single-column ASCII table work.
+ * Fix a bug so a new table constructed from an existing table with
+ X-formatted columns will work.
+ * Fix a problem in verifying HDUList right after the open statement.
+ * Verify that elements in an HDUList, besides the first one, are
+ ExtensionHDU.
+ * Add output verification in methods flush() and close().
+ * Modify the the design of the open() function to remove the
+ output_verify argument.
+ * Remove the groups argument in GroupsHDU's contructor.
+ * Redesign the column definition class to make its column components
+ more accessible. Also to make it conducive for higher level
+ functionalities, e.g. combining two column definitions.
+ * Replace the Boolean class with the Python Boolean type. The old
+ TRUE/FALSE will still work.
+ * Convert classes to the new style.
+ * Better format when printing card or card list.
+ * Add the optional argument clobber to all writeto() functions and
+ methods.
+ * If adding a blank card, will not use existing blank card's space.
+
+ PyFITS Version 1.0 REQUIRES Python 2.3 or later.
+ _________________________________________________________________
+
+Version 0.9.6; 11 November 2004
+
+ Major changes since v0.9.3:
+
+ * Support for variable length array tables.
+ * Support for writing ASCII table extensions.
+ * Support for random groups, both reading and writing.
+
+ Some minor changes:
+
+ * Support for numbers with leading zeros in an ASCII table
+ extension.
+ * Changed scaled columns' data type from Float32 to Float64 to
+ preserve precision.
+ * Made Column constructor more flexible in accepting format
+ specification.
+ _________________________________________________________________
+
+Version 0.9.3; 2 July 2004
+
+ Changes since v0.9.0:
+
+ * Lazy instanciation of full Headers/Cards for all HDU's when the
+ file is opened. At the open, only extracts vital info (e.g.
+ NAXIS's) from the header parts. This change will speed up the
+ performance if the user only needs to access one extension in a
+ multi-extension FITS file.
+ * Support the X format (bit flags) columns, both reading and
+ writing, in a binary table. At the user interface, they are
+ converted to Boolean arrays for easy manipulation. For example, if
+ the column's TFORM is "11X", internally the data is stored in 2
+ bytes, but the user will see, at each row of this column, a
+ Boolean array of 11 elements.
+ * Fix a bug such that when a table extension has no data, it will
+ not try to scale the data when updating/writing the HDU list.
+ _________________________________________________________________
+
+Version 0.9; 27 April 2004
+
+ Changes since v0.8.0:
+
+ * Rewriting of the Card class to separate the parsing and
+ verification of header cards
+ * Restructure the keyword indexing scheme which speed up certain
+ applications (update large number of new keywords and reading a
+ header with larger numbers of cards) by a factor of 30 or more
+ * Change the default to be lenient FITS standard checking on input
+ and strict FITS standard checking on output
+ * Support CONTINUE cards, both reading and writing
+ * Verification can now be performed at any of the HDUList, HDU, and
+ Card levels
+ * Support (contiguous) subsection (attribute .section) of images to
+ reduce memory usage for large images
+
+Version 0.8.0; August 19, 2003
+
+ NOTE: This version will only work with numarray Version 0.6. In
+ addition, earlier versions of PyFITS will not work with numarray 0.6.
+ Therefore, both must be updated simultaneously.
+
+ Changes since 0.7.6:
+ * Compatible with numarray 0.6/records 2.0
+ * For binary tables, now it is possible to update the original array
+ if a scaled field is updated.
+ * Support of complex columns
+ * Modify the __getitem__ method in FITS_rec. In order to make sure
+ the scaled quantities are also viewing ths same data as the
+ original FITS_rec, all fields need to be "touched" when
+ __getitem__ is called.
+ * Add a new attribute mmobject for HDUList, and close the memmap
+ object when close HDUList object. Earlier version does not close
+ memmap object and can cause memory lockup.
+ * Enable 'update' as a legitimate memmap mode.
+ * Do not print message when closing an HDUList object which is not
+ created from reading a FITS file. Such message is confusing.
+ * remove the internal attribute "closed" and related method
+ (__getattr__ in HDUList). It is redundant.
+
+Version 0.7.6; November 22, 2002
+
+ NOTE: This version will only work with numarray Version 0.4.
+
+ Changes since 0.7.5:
+ * Change x*=n to numarray.multiply(x, n, x) where n is a floating
+ number, in order to make pyfits to work under Python 2.2. (2
+ occurrences)
+ * Modify the "update" method in the Header class to use the
+ "fixed-format" card even if the card already exists. This is to
+ avoid the mis-alignment as shown below:
+ After running drizzle on ACS images it creates a CD matrix whose
+ elements have very many digits, e.g.:
+CD1_1 = 1.1187596304411E-05 / partial of first axis coordinate w.r.t. x
+CD1_2 = -8.502767249350019E-06 / partial of first axis coordinate w.r.t. y
+ with pyfits, an "update" on these header items and write in new
+ values which has fewer digits, e.g.:
+CD1_1 = 1.0963011E-05 / partial of first axis coordinate w.r.t. x
+CD1_2 = -8.527229E-06 / partial of first axis coordinate w.r.t. y
+ * Change some internal variables to make their appearance more
+ consistent:
+ old name new name
+
+ __octalRegex _octalRegex
+ __readblock() _readblock()
+ __formatter() _formatter().
+ __value_RE _value_RE
+ __numr _numr
+ __comment_RE _comment_RE
+ __keywd_RE _keywd_RE
+ __number_RE _number_RE.
+ tmpName() _tmpName()
+ dimShape _dimShape
+ ErrList _ErrList
+ * Move up the module description. Move the copywright statement to
+ the bottom and assign to the variable __credits__.
+ * change the following line:
+self.__dict__ = input.__dict__
+ to
+self.__setstate__(input.__getstate__())
+ in order for pyfits to run under numarray 0.4.
+ * edit _readblock to add the (optional) firstblock argument and
+ raise IOError if the the first 8 characters in the first block is
+ not 'SIMPLE ' or 'XTENSION'. Edit the function open to check for
+ IOError to skip the last null filled block(s). Edit readHDU to add
+ the firstblock argument.
+ _________________________________________________________________
+
+Version 0.7.5; 16 August 2002
+
+ Changes since v0.7.3:
+
+ 1. Memory mapping now works for readonly mode, both for images and
+ binary tables.
+ Usage: pyfits.open('filename', memmap=1)
+ 2. Edit the field method in FITS_rec class to make the column scaling
+ for numbers use less temporary memory. (does not work under 2.2,
+ due to Python "bug" of array *=)
+ 3. Delete bscale/bzero in the ImageBaseHDU constructor.
+ 4. Update bitpix in BaseImageHDU.__getattr__ after deleting
+ bscale/bzero. (bug fix)
+ 5. In BaseImageHDU.__getattr__ point self.data to raw_data if float
+ and if not memmap. (bug fix).
+ 6. Change the function get_tbdata() to private: _get_tbdata().
+ _________________________________________________________________
+
+ Version 0.7.3; 12 July 2002
+
+ Changes since v0.7.2:
+ 1. It will scale all integer image data to Float32, if BSCALE/BZERO
+ != 1/0. It will also expunge the BSCALE/BZERO keywords.
+ 2. Add the scale() method for ImageBaseHDU, so data can be scaled
+ just before being written to the file. It has the following
+ arguments:
+
+ type:
+ destination data type (string), e.g. Int32, Float32,
+ UInt8, etc.
+
+ option:
+ scaling scheme. if 'old', use the old BSCALE/BZERO
+ values. if 'minmax', use the data range to fit into the
+ full range of specified integer type. Float destination
+ data type will not be scaled for this option.
+
+ bscale/bzero:
+ user specifiable BSCALE/BZERO values. They overwrite the
+ "option".
+
+ 3. Deal with data area resizing in 'update' mode.
+ 4. Make the data scaling (both input and output) faster and use less
+ memory.
+ 5. Bug fix to make column name change takes effect for field.
+ 6. Bug fix to avoid exception if the key is not present in the header
+ already. This affects (fixes) add_history(), add_comment(), and
+ add_blank().
+ 7. Bug fix in __getattr__() in Card class. The change made in 0.7.2
+ to rstrip the comment must be string type to avoid exception.
+ _____________________________________________________________
+
+ Version 0.7.2.1; June 25, 2002
+ A couple of bugs were addressed in this version.
+ + Fix a bug in _add_commentary(). Due to a change in index_of()
+ during version 0.6.5.5, _add_commentary needs to be modified
+ to avoid exception if the key is not present in the header
+ already. This affects (fixes) add_history(), add_comment(),
+ and add_blank().
+ + Fix a bug in __getattr__() in Card class. The change made in
+ 0.7.2 to rstrip the comment must be string type to avoid
+ exception.
+ _____________________________________________________________
+
+ Version 0.7.2; June 19, 2002
+ The two major improvements from Version 0.6.2 are:
+ + support reading tables with "scaled" columns (e.g.
+ tscal/tzero, Boolean, and ASCII tables)
+ + a prototype output verification.
+ This version of PyFITS requires numarray version 0.3.4.
+ Other changes include:
+
+ 1. Implement the new HDU hierarchy proposed earlier this year. This
+ in turn reduces some of the redundant methods common to several
+ HDU classes.
+ 2. Add 3 new methods to the Header class: add_history, add_comment,
+ and add_blank.
+ 3. The table attributes _columns are now .columns and the attributes
+ in ColDefs are now all without the underscores. So, a user can get
+ a list of column names by: hdu.columns.names.
+ 4. The "fill" argument in the new_table method now has a new meaning:
+ If set to true (=1), it will fill the entire new table with
+ zeros/blanks. Otherwise (=0), just the extra rows/cells are filled
+ with zeros/blanks. Fill values other than zero/blank are now not
+ possible.
+ 5. Add the argument output_verify to the open method and writeto
+ method. Not in the flush or close methods yet, due to possible
+ complication.
+ 6. A new copy method for tables, the copy is totally independent from
+ the table it copies from.
+ 7. The tostring() call in writeHDUdata takes up extra space to store
+ the string object. Use tofile() instead, to save space.
+ 8. Make changes from _byteswap to _byteorder, following corresponding
+ changes in numarray and recarray.
+ 9. Insert(update) EXTEND in PrimaryHDU only when header is None.
+ 10. Strip the trailing blanks for the comment value of a card.
+ 11. Add seek(0) right after the __buildin__.open(0), because for the
+ 'ab+' mode, the pointer is at the end after open in Linux, but it
+ is at the beginning in Solaris.
+ 12. Add checking of data against header, update header keywords
+ (NAXIS's, BITPIX) when they don't agree with the data.
+ 13. change version to __version__.
+
+ There are also many other minor internal bug fixes and technical
+ changes.
+ _________________________________________________________________
+
+ Version 0.6.2; February 12, 2002
+
+ This version requires numarray version 0.2.
+
+ Things not yet supported but are part of future development:
+
+ * Verification and/or correction of FITS objects being written to
+ disk so that they are legal FITS. This is being added now and
+ should be available in about a month. Currently, one may construct
+ FITS headers that are inconsistent with the data and write such
+ FITS objects to disk. Future versions will provide options to
+ either a) correct discrepancies and warn, b) correct discrepancies
+ silently, c) throw a Python exception, or d) write illegal FITS
+ (for test purposes!).
+ * Support for ascii tables or random groups format. Support for
+ ASCII tables will be done soon (~1 month). When random group
+ support is added is uncertain.
+ * Support for memory mapping FITS data (to reduce memory demands).
+ We expect to provide this capability in about 3 months.
+ * Support for columns in binary tables having scaled values (e.g.
+ BSCALE or BZERO) or boolean values. Currently booleans are stored
+ as Int8 arrays and users must explicitly convert them into a
+ boolean array. Likewise, scaled columns must be copied with
+ scaling and offset by testing for those attributes explicitly.
+ Future versions will produce such copies automatically.
+ * Support for tables with TNULL values. This awaits an enhancement
+ to numarray to support mask arrays (planned). (At least a couple
+ of months off).
