- Update to version 4.2.0:
- This release includes patches to security vulnerabilities.
We strongly encourage this upgrade, particularly for those
running CFITSIO in web accessible applications.
- Fix to fits_read_key function, which was failing to properly
read keywords declared type TUINT on compilers where
sizeof(int) = sizeof(long).
- Added new functions fits_read_cols and fits_write_cols to
efficiently read or write multiple columns in a single
function call
- Added new function fits_copy_selrows to copy only selected
rows, such as the selected rows returned by fits_find_rows
- Added new calculator functions ERF(X), ERFC(X) and GAMMA(X),
which are mathematical special functions of the same name
- Added new calculator function GTIFIND() which reports which
GTI row brackets a given time sample
- Added new calculator functions which operate upon vector table
values NAXIS(V), NAXES(V,n), ELEMENTNUM(V) and AXISELEM(V,n),
and ARRAY(X,d) which promotes scalar X to a vector or array
with given dimensions.
- The CFITSIO histogramming code now handles binning by any
arbitrary calculator expression rather than just a column name.
Both the binned columns as well as the optional weights may be
calculator expressions, enclosed in parentheses.
- Binning of vector columns or expressions is now supported, as
long as all binned inputs (as well as the optional weighting)
have the same vector dimensions. Binning of variable-length
columns remains unsupported.
- A bug that caused histogram weights from columns that are null
values to be tallied along with non-null values has been fixed.
- The CFITSIO calculator and histogramming functionality is now
fully reentrant and does not require multithreading interlocks.
- A long-standing segmentation fault bug in the histogramming
code related to binning any value using the "reciprocal" /XXXX
notation has been fixed.
- Added mutex locks for thread safety in ftgiou and ftfiou.
- Added several Fortran wrappers to support image read/write when
'fpixel' and 'nelements' are 8-byte integers.
- Fixed bug which was adding spaces to some cases of long string
key value output.
- Enable SSE2 on x86_64
- Package fitscopy util
- Enable bzip2 support
