* The manual chapters describing the introduction, EBNF, literals
(for integer, bigInteger, float, char and string), set operations
and file I/O have been improved.
* Operations, to get an array slice with a specified length, have
been added to the libraries array.s7i and idxarray.s7i.
* Array aggregates for arrays with a given start index have been
added to idxarray.s7i.
* Functions for binomial coefficient and modular exponentiation have
been added to the library bigint.s7i.
* A definition of an empty set with the name {} has been added to
bitset.s7i.
* Functions to compute the minimum and maximum have been added to the
libraries integer.s7i and float.s7i.
* Documentations comments in keybd.s7i have been improved.
* In pixmap_file.s7i the logic of a writeln after a setPosXY has been
changed. Now the writeln moves one line downward relative to the
position given with setPosXY.
* A pound symbol has been added to several bitmap fonts.
* A standard bitmap font, with capital height of 9, has been defined
in the new library stdfont9.s7i.

been added to chkbig.sd7.
* The comanche webserver has been improved to accept cookies.
* The compiler has been improved to generate better code for the
allocation of array memory.
* The function arrMalloc in arr_rtl.c has been improved to avoid an
overflow, when the size of the memory is computed.
* The functions arrSubarr and arrSubarrTemp have been added to
arr_rtl.c.
* Support for the action ARR_SUBARR has been added to the compiler.
* The macros arraySize and arraySize2 have been defined in common.h
and used in arrlib.c, arr_rtl.c, arrutl.c, cmdlib.c, cmd_unx.c and
cmd_win.c.
* Definitions of INT64TYPE_MIN, INTTYPE_MIN and MIN_MEM_INDEX have
been added to common.h.
