    Release Notes: The FAQ has been improved. The compiler has been improved to optimize the concatenation of three or more strings with strConcatN and to store the characters of string constants with more density. The compiler has been improved to define and use dynamic (virtual) destructors for interface types. The interpreter and compiler have been improved to use reference counting (usage_count) for all objects of the category STRUCTOBJECT. The string search functions (pos) have been improved to use a modified Boyer–Moore string search algorithm. The performance of the function replace2 has been improved.

      Release Notes: The library editline.s7i has been added. It defines a file type for linewise editing with history. The manual chapter describing types, especially the type program, has been improved. The calc.sd7 example has been improved to allow linewise editing. The handling of the internal program representation in interpreter and compiler has been improved to free most unused memory. The stack trace has been improved to display infix operators better and to write parameter names. The functions copy_expression and free_expression have been optimized. The free list management has been made configurable.

        Release Notes: The description of exceptions in the manual has been improved. The handling of program data in the interpreter and compiler has been improved to free more unused memory. The Seed7 compiler has been improved to support releasing unused programs. The function prgDestr has been improved to free (most of) the data used by a program. Several functions have been improved to call prgDestr. Several actions in the interpreter have been improved to work correctly for arrays with interface elements. The functions prgCpy and prg_cpy have been improved to free a program when the usage_count reaches zero.

The library gzip.s7c has been improved to decode blocks with fixed Huffman codes. Support for bigInteger literals with bases other than 10 has been added. The str functions have been changed such that str(48879, 16) returns "beef". The program make7.sd7 has been improved to support multiple targets and the option -C. The handling of floating point divisions in the compiler has been improved. The makefile mk_clang.mak has been added to support the clang C compiler.

                  Release Notes: The Seed7 compiler was renamed to s7c. The program make7.sd7 was improved to allow macros in the command line. The libraries makedata.s7i and make.s7i were improved. A variant of the function popen was added to shell.s7i. The difference between & and <& was explained in the FAQ. The program tar7.sd7 was improved to accept DOS paths for all file arguments. Documentation comments were added to several files. The graphic drivers were improved to exit a program when the close button (X) is pressed. The makefiles were improved such that 'make s7c' generates an executable of the Seed7 compiler.
