                                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   This release fixed a memory leak due 
                             HJB)      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_cbf_logfile,                   
                                       cbf_make_widefile, cbf_read_anyfile,   
                                       cbf_read_widefile,                     
                                       cbf_write_local_file,

     0.7.7     February 2007   HJB       This release reflects changes for    
                                       base 32K support developed by G.       
                                       Darakev, and changes for support of

                                       change the treatment of the byteorder  
                                       parameter from strcpy semantics to     
                                       return of a pointer to a string        
                                       constant. Our thanks to E. Eikenberry
