  • New "*" parameter to support tags with variable arguments
  • Fixed parsing of html comments and embedded PHP code.
  • The ‘$’-operator now works in comments and PHP code.
  • When ‘$’ is used without curly braces, the scope is now more intuitive.
  • Removed crash when htp is invoked with an illegal option.
  • Made error messages more understandable.
  • Fixed parsing of jpeg files to support extended formats.
  • Preserve white-spaces in HTML-tags as much as possible.
  • Don't allow white-spaces between attribute name and value any more.
• Version 1.13 (26 May 2002)
  • htp becomes SourceForge project
  • New location for on-line documentation, http://htp.sourceforge.net/ref/
  • The ‘$’-operator can be nested.
  • New tags: BLOCKDEF, INC, OUTPUT, QUOTE, WHILE
  • New attributes EXPAND and GLOBAL
  • Environment variables are now accessible as macros
  • New predefined macros: _htpfile_out, _htpfile_in
  • New "semi-condensed" mode
  • IMG tag supports png images.
• Version 1.12 (13 Jul 2001)
  • New location for on-line documentation, http://math.newcastle.edu.au/~rking/htp/
• Version 1.11 (27 Oct 2000)
  • New location for on-line documentation, http://www.ens.gu.edu.au/robertk/
  • First release by new maintainer, Robert King.
  • No change to behaviour of program from 1.10 at all.
• Version 1.10 (23 Sep 1996)
  • Fixed a bug in the memory suballocator. Some CPUs will fault on non-DWORD aligned accesses, which suballoc does continuously. Essentially, htp will coredump almost immediately. Fixed.
  • Allan Todds pointed out a rather severe limitation regarding how htp handles HTML comments. If the comments are too long, htp would puke. This is a particular problem because JavaScript and VBScript are embedded inside a single comment. This has been fixed.
  • The memory suballocator has a new feature to release memory back to the system heap if it grows past a preset bound.
  • Richard Crane pointed out a real bugger: response files would not work with tabs or multiple spaces between file names. Fixed on both counts.
  • From Mark Roedel's suggestion, I've added comments to response files.
  • Metatags added!
• Version 1.00 (11 Aug 1996)
  • Broke down and gave in ... time for a real release.
  • Added parameter support for FILE INCLUDE and BLOCK macros expanded with the USE tag.
  • $ macro expansion can now occur anywhere in a markup: the tag name, an attribute name, or an attribute value.
  • New memory allocator (suballoc.c) added, and several memory leaks found and squashed. Increased performance as well.
  • Finally! Added support for default ALT text for image files.
• Version 0.16 (3 Apr 1996)
  • Support for project default files added.
  • New CONDENSE option added.
  • FILE TIME and DATE now report the source file's time and date, and not the current.
  • Options can now be placed in response files.
  • Options are processed in a single module rather than haphazardly throughout the code.
  • Support for using different delimiters around htp markups added. htp markups can now be surrounded by curly braces or square brackets. See Creating htp files for more information.
  • File templates now formally supported.
• Version 0.15 (18 Jan 1996)
  • Macro store revised with hash table for faster lookups.
  • JPEG support finally added.
  • htp will now delete incomplete output files unless the PRECIOUS option is used.
  • Automatically places quotation marks around a macro expanded inside a markup provided it is not surrounded by other text. See USE for more detailed information.
  • Previously, the macro parser did not escape dual '$' characters. Fixed.
  • Added support for a defaults file. See Default files for more information.
  • Added support for an include file search path. See FILE for more information.
  • FILE TIME and FILE DATE now accept values, which are interpreted as formatting characters to display the time or the date. See FILE for more information and warnings.
  • FILE EXECUTE implemented.
• Version 0.14 (10 Dec 1995)
  • Ported old linear-style readme.txt file to friendly, clean HTML on-line reference you are now using. 8-)
  • Block macros can now be embedded inside another block macro.
  • Hell's bells ... was not checking that macro existed before dereferencing.
  • Added dependency checking. htp will now only build the output file if any of the input files have changed (according to file timestamps). Can be disabled with the NODEPEND option.
  • Added some additional code to prevent numerous (but harmless) compiler warnings.
  • Added FILE SIZE, FILE DATE, and FILE TIME that works in conjunction with a NAME attribute to report respective information for an external file.
  • Switched to large model for DOS version, to avoid memory constraints of small model.
• Version 0.13 (2 Nov 1995)
  • Added the UNSET tag.
  • Fixed bug related to re-defining macros and defining null-length macros.
  • Can now declare multiple SET macros in the same tag.
  • Various code issues brought to my attention by Joseph Dandrea of AT&T Bell Laboratories (joseph.dandrea@att.com). Joseph provided many helpful insights and pointed out many potential problems in a massive (and desparately needed) code review. htp is a much stronger program thanks to his excellent support.
  • In both response files and FILE INCLUDE's, the directory delimiter (forward slash in UNIX, backwards slash in MS-DOS) is parsed to match the native filesystem ... in other words, no need to change sources when moving from UNIX to DOS or vice-versa. Suggested by Chris Jobling (C.P.Jobling@swansea.ac.uk).
  • IFNOT tag removed, replaced with IF NOT, which is more compliant with HTML.
  • Braces around macros implemented.
  • htp was leaving linefeeds for lines that contained stripped-out tags. The resulting HTML was somewhat sloppy. Fixed.
  • Error and warning reporting made more consistent
• Version 0.12 (3 Oct 1995)
  • Ported source code to Linux. Code should also be portable to other UNIX-type operating systems as well.
• Version 0.11 (6 Sep 1995)
  • Cleaned up the code for portability and maintainability.
  • Added conditionals (IF, NOT, ELSE, /IF).
  • Added block macros (BLOCK, /BLOCK).
  • Added response files.
• Version 0.10 (26 Aug 1995)
  • Initial release. Many features unimplemented.
