Version 3.61.3 of 4tH compiler
Release Notes: Unions and pragmas can be defined. The library files now support several polynomials, RAM disks, menus, bitfields, bit arrays, several new sorting algorithms, Morse signs, and 3VL. The preprocessor was enhanced, supporting S\", token concatenation, string comparison, variable assignment, and smart double number/FP literals. 'DOES>' can be used to change the execution semantics of basic data types. A bug in the Linux Makefile was fixed. Overflow and underflow errors in number conversion were fixed. A bug in the 'IF' statement of 4tsh was fixed. The accuracy of the 'FERF' words was improved.
Other releases
Release Notes: The library files now support stem-leaf plots, finite difference, compass boxing, HTML and XML character entities, Hamming (7,4) codes, Base64 conversion, FEXPM1, and FLNP1. Preprocessor macros can be undefined with the 'SCRAP:' keyword, and simple flow control was added. PAD size is increased to 768 characters to make pictured numeric output 64-bit compliant. The accuracy of FSINH, FCOSH, FTANH, FASIN, FACOS, and FATAN was significantly improved. The words '[ELSE]' and '[IGNORE]' have been added. Coherent 4.2.x and Android 3.x ports are now available.

Release Notes: Specific code can be executed after a failed 'WHILE' just before exiting the loop. Binary strings can be tagged individually. The library files now support UTF-8 to GBK/2 conversion (and vice versa), infix formula translation, string pattern matching, finite state machines, statistical functions, enhanced command line parsing and the full range of ANS Forth floating point words for ZEN float. The preprocessor now supports string parsing with custom delimiters, macros within macros, and a string stack. A Markov engine and an infix-to-postfix converter were added to the examples.
Release Notes: A peephole optimizer was added. The library files now support a tiny database management system, double number multiplication, double number division, LaTeX file generation, and the XCHAR wordset. SEEK can now be used to reposition the file to the end. The words 2NIP and [FORCE] were added. Several obscure bugs were fixed. Support for 64-bit architectures was greatly improved. On Linux, compilation is now staged. A nuclear test simulation was added to the preprocessor examples.
Release Notes: The words ’DELETE-FILE’ and ’ENVIRON@’ have been added. The library files now support writing OpenOffice, KOffice, and Microsoft XML spreadsheets, different sorting algorithms, the creation of floating point interpreters, GTK-server, Forth compatible floating point I/O for ZEN float, portable bitmap graphics and Turtle graphics. Files can now be deleted and environment variables can be queried. The maximum symbol length is increased to 23 characters. Two tiny spreadsheet programs were added to the examples.
