## Version History

Version | Date | By | Description
--- | --- | --- | ---
0.1 | Apr. 1998 | PJE | This was the first CBFlib release. It supported binary CBF files using binary strings.
0.2 | Aug. 1998 | HJB | This release added ascii imgCIF support using MIME-encoded binary sections, added the option of MIME headers for the binary strings was well. MIME code adapted from mpack 1.5. Added hooks needed for DDL1-style names without categories.
0.3 | Sep. 1998 | PJE | This release cleaned up the changes made for version 0.2, allowing multi-threaded use of the code, and removing dependence on the mpack package.
0.4 | Nov. 1998 | HJB | This release merged much of the message digest code into the general file reading and writing to reduce the number of passes. More consistency checking between the MIME header and the binary header was introduced. The size in the MIME header was adjusted to agree with the version 0.2 documentation.
0.5 | Dec. 1998 | PJE | This release greatly increased the speed of processing by allowing for deferred digest evaluation.
0.6 | Jan. 1999 | HJB | This release removed the redundant information (binary id, size, compression id) from a binary header when there is a MIME header, removed the unused repeat argument, and made the memory allocation for buffering and tables with many rows sensitive to the current memory allocation already used.
0.6.1 | Feb. 2001 | HP (per HJB) | This release fixed a memory leak due to misallocation by size of cbf_handle instead of cbf_handle_struct
0.7 | Mar. 2001 | PJE | This release added high-level instructions based on the imgCIF dictionary version 1.1.
0.7.1 | Mar. 2001 | PJE | The high-level functions were revised to permit future expansion to files with multiple images.
0.7.2 | Apr. 2001 | HJB | This release adjusted cbf_cimple.c to conform to cif_img.dic version 1.1.3
0.7.2.1 | May 2001 | PJE | This release corrected an if nesting error in the prior mod to cbf_cimple.c.
0.7.3 | Oct. 2002 | PJE | This release modified cbf_simple.c to reorder image data on read so that the indices are always increasing in memory (this behavior was undefined previously).
0.7.4 | Jan 2004 | HJB | This release fixes a parse error for quoted strings, adds code to get and set character string types, and removes compiler warnings
0.7.5 | Apr 2006 | HJB | This release cleans up some compiler warnings, corrects a parse error on quoted strings with a leading blank as adds the new routines for support of aliases, dictionaries and real arrays, higher level routines to get and set pixel sizes, do cell computations, and to set beam centers, improves support for conversion of images, picking up more data from headers.
0.7.6 | Jul 2006 | HJB | This release reorganizes the kit into two pieces: CBFlib_0.7.6_Data_Files and CBFlib_0.7.6. An optional local copy of getopt is added. The 1.4 draft dictionary has been added. cif2cbf updated to support vcif2 validation. convert_image and cif2cbf updated to report text of error messages. convert_image updated to support tag and category aliases, default to adxv images. convert_image and img updated to support row-major images. Support added for binning. API Support added for validation, wide files and line folding. Logic changed for beam center reporting. Added new routines: cbf_validate, cbf_get_bin_sizes, cbf_set_bin_sizes, cbf_find_last_typed_child, cbf_compose_itemname, cbf_set_cbf_logfile, cbf_make_widefile, cbf_read_anyfile, cbf_read_widefile, cbf_write_local_file, cbf_write_widefile, cbf_column_number, cbf_blockitem_number, cbf_log, cbf_check_category_tags, cbf_set_beam_center
0.7.7 | February 2007 | HJB | This release reflects changes for base 32K support developed by G. Darakev, and changes for support of reals, 3d arrays, byte_offset compression and J. P. Abrahams packed compression made in consultation with (in alphabetic order) E. Eikenberry, A. Hammerley, W. Kabsch, M. Kobas, J. Wright and others at PSI and ESRF in January 2007, as well accumulated changes fixing problems in release 0.7.6.
0.7.7.1 | February 2007 | HJB | This release is a patch to 0.7.7 to change the treatment of the byteorder parameter from strcpy semantics to return of a pointer to a string constant. Our thanks to E. Eikenberry for pointing out the problem.
0.7.7.2 | February 2007 | HJB | This release is a patch to 0.7.7.1 to add testing for JPA packed compression and to respect signs declared in the MIME header.
0.7.7.3 | April 2007 | HJB | This release is a patch to 0.7.7.3 to add f90 support for reading of CBF byte-offset and packed compression, to fix problems with gcc 4.4.1 and to correct errors in multidimensional packed compression.
