CHANGES IN HTMLDOC v1.8.9

    NEW FEATURES

	- Added a "--no-numbered" option to turn heading numbers
	  off.
	- Added support for "keywords" META data.
	- Added support for BMP images.
	- Added support for ROWSPAN attribute in tables.
	- Added support for HTTP file references.
	- Added new sample CGI program that can produce a PDF
	  file for any page on a server.
	- Added new n/N, date, and time formats for the header
	  and footer.

    CHANGES

	- Configuration script changes.
	- Now ignore file count in book files; instead, we now
	  look at the first character of the third and
	  subsequent lines - a dash (-) indicates the start of
	  the options. (use a backslash to quote filenames
	  starting with a dash)
	- Multiple-line paragraphs that have only 1 line on the
	  bottom of the current page are now started on the
	  following page.
	- DSC comments in PostScript output were not 100%
	  conformant with the DSC spec.
	- Long table-of-contents entries are now wrapped
	  (original patch supplied by Richard Pennington)
	- New color icon under UNIX when Xpm library available.

    BUG FIXES

	- Didn't allow &#nnn; character escapes inside
	  preformatted text.
	- Empty TBODY groups would cause parse_table() to
	  crash.
	- Comments were incorrectly terminated by ">" instead of
	  "-->".
	- The command-line and GUI interfaces looked for
	  "outlines" instead of "outline" for the page mode.
	- The HTML output code didn't output closing tags for
	  empty elements.
	- The GUI interface started with the compression
	  slider enabled, even for HTML output.
	- The beginnings of some lines could start with
	  whitespace.
	- Wasn't aligning images and text on lines based on the
	  line height.
	- The compression slider was enabled in the GUI even
	  though HTML output was selected.
	- The Perl example code was incorrect.
	- Fixed the check for whether or not pages were
	  generated.
	- htmlSetCharSet() wasn't reloading the character set
	  data if the data directory changed.
	- The GUI did not reset the default background color.
	- The 'C' page number style (chapter page numbers) started
	  at 3 instead of 1.
	- The chapter links were off by 1 or 2 pages when no title
	  page was included.


CHANGES IN HTMLDOC v1.8.8

    NEW FEATURES

	- Added support for PDF security/encryption!
	- Now support TABLE height attribute.
	- Now generate an error message if no pages are
	  generated (with a suggestion to use the webpage
	  option.)
	- New "paths" option to specify additional directories
	  to search for files.  This is useful when the source
	  files use absolute server paths.

    CHANGES

	- Added missing casts in htmllib.cxx that were causing a
	  compile warning with some compilers.
	- No longer draw borders around empty cells in tables..
	- Now disable the TOC tab when using webpage mode.
	- Now scale title image to 100% in HTML output.
	- Now handle comments with missing whitespace after the
	  "<!--".

    BUG FIXES

	- Nested tables didn't take into account the table
	  border width, spacing, or padding values.
	- HTMLDOC crashed under Solaris when reading HTML files
	  from the standard input.
	- <ELEM>text</ELEM> <MELE>text</MELE> was rendered
	  without an intervening space.


CHANGES IN HTMLDOC v1.8.7

    NEW FEATURES

	- The configure script now uses the local PNG, ZLIB,
	  and/or JPEG libraries when they are new enough.
	- The configure script now uses the -fno-rtti,
	  -fno-exceptions, and -fpermissive options as needed
	  with GCC (smaller, faster executables, works around X
	  header bugs in Solaris.)
	- Added a --toctitle option to set the table-of-contents
	  title from the command-line (was only available in the
	  GUI in previous releases...)
	- New "<!-- NEED amount -->" comment to force a page
	  feed if there is not sufficient room on the page for
	  the following text.
	- Page comments are now supported in tables.
	- Table rows are now allocated dynamically, MAX_ROWS at
	  a time.

    CHANGES

	- Increased default MAX_PAGES to 10000 (was 5000.)
	- File links in book files now point to the top of the
	  next page.
	- <TABLE ALIGN=xyz> now aligns the table (previously it
	  just set the default alignment of cells.)
	- Transparent GIFs now use the body color instead of white
	  for the transparent color.
	- Updated to LIBPNG 1.0.6 in source distribution.
	- Updated the default cellpadding to be 1 pixel to match
	  Netscape output.
	- Updated line and block spacing to match Netscape.
	- DL/DT/DD output now matches browsers (was indented from
	  browser output.)
	- Now only output link (A) style if it is set to "none".
	  Otherwise Netscape would underline all targets as well
	  as links.
	- Increased the MAX_COLUMNS constant to 200, and dropped
	  MAX_ROWS to 200. Note that the new table code now
	  allocates rows in increments of MAX_ROWS rows, so the
	  actual maximum number of rows depends on available
	  memory.

    BUG FIXES

	- Now ignore illegal HTML in tables.
	- The VALIGN code didn't handle empty cells properly.
	- Wasn't offsetting the start of each row by the cell
	  padding.
	- The JPEG image loading code didn't work for some JPEG
	  images, particularly those from digital cameras (JPEG
	  but not JFIF format.)
	- The strikethrough line was not being drawn in the
	  correct position.
	- Wasn't setting the height of BR elements, so <BR><BR>
	  didn't insert a blank line.
	- The table of contents would show the wrong page numbers
	  if no title page was generated.
	- Cell widths did not subtract any border, padding, or
	  spacing from the "preferred" width, causing formatting
	  differences between web browsers and HTMLDOC.
	- The PNG loading code did not handle interlacing or
	  transparency.
	- The HTML parsing code did not prevent elements in
	  embedded files from completing elements in the parent
	  file.
	- The table CELLSPACING amount was being applied twice in
	  the table sizing calculations.


CHANGES IN HTMLDOC v1.8.6

    NEW FEATURES

	- New linkcolor and linkstyle options.

    CHANGES

	- Minor source changes for OS/2 compilation.
	- SUP and SUB now raise/lower text more to be consistent with
	  browser look-n-feel.
	- Non-breaking space by itself was being output.  Now check for
	  that and ignore strings that consist entirely of whitespace.
	- New progress bar.

    BUG FIXES

	- Didn't add whitespace after a table caption.
	- Nested tables caused formatting problems (flatten_tree()
	  didn't insert breaks for new rows)
	- A cell whose minimum width exceeded the available width
	  for the table would cause the table to go off the page.
	- Cells that spanned more than two pages were drawn with boxes
	  around them rather than just the sides.
	- The stylesheet info in the HTML output specified the H1 size
	  for all headings.
	- The title page was incorrectly formatted when an image was
	  specified - the text start position was computed using the
	  pixel height of the title image and not the formatted height.
	- 1 color images didn't come out right; the "fix" to work around
	  an Acrobat Reader bug was being done too soon, so the color
	  lookups were wrong.
	- HTML file links now work properly.
	- Now limit all HTML input to the maximum size of input buffers
	  to avoid potential buffer overflow problems in CGIs.
	- If a row had a predefined height, HTMLDOC wasn't making sure
	  that the row would fit on the current page.
	- THEAD, TFOOT, and TBODY caused problems when formatting tables.
	  Note: THEAD and TFOOT are *still* not supported, however the
	  code now properly ignores them and parses the rows in the
	  TBODY group.
	- The VALIGN code introduced in the 1.8.5 release didn't check
	  for NULL pointers in all cases.


CHANGES IN HTMLDOC v1.8.5

    NEW FEATURES

	- New "--titlefile" option to include an HTML file for
	  the title page(s).
	- New 'C' header/footer option to show current page
	  number within chapter or HTML file.
	- Allow adding of .book files to import all HTML files
	  in the book.
	- New "HALF PAGE" page comment to feed 1/2 page.
	- Added VALIGN and HEIGHT support in tables.

    CHANGES

	- Now optimize link objects in PDF files (provides a 40k
	  reduction in file size for the HTMLDOC manual alone)
	- Table rows that cross page boundaries are now rendered
	  more like Netscape and MSIE.
	- Now support HTMLDOC_DATA and HTMLDOC_HELP environment
	  variables under UNIX (for alternate install directory)
	- Now show error messages when HTMLDOC can't open the
	  AFM, character set, or PostScript glyph files.
	- The logo image is now scaled to its "natural" size (as
	  it would appear in a web browser)
	- Now recognize VALIGN="MIDDLE" or VALIGN="CENTER".

    BUG FIXES

	- Generation of PDF files to the standard output (i.e.
	  to the web server + browser) didn't work on some
	  versions of UNIX.  HTMLDOC now writes the PDF output
	  to a temporary file and then copies it to the standard
	  output as needed.
	- PDF links were missing the first 5 characters in the
	  filename; the code was trying to skip over the "file:"
	  prefix, but that prefix was already skipped elsewhere.
	- Nested descriptive lists (DL) did not get rendered
	  properly.
	- Tables had extra whitespace before and after them.
	- Multiple aligned images confused parse_paragraph();
	  the images would overlap instead of stack on the
	  sides.


CHANGES IN HTMLDOC v1.8.4

    CHANGES

	- More configure script changes for FLTK DSOs.
	- FileIcon.cxx was still using NULL for outline (an
	  integer), which caused some ANSI C++ compilers to
	  complain.

    BUG FIXES

	- The Fonts and Colors tab groups did not extend to
	  the full width of the tab area, which prevented the
	  Browse button from working when clicked on the right
	  side.
	- The help dialog window did not scroll all the way to
	  the bottom of the text.
	- The chapter ("c") header/footer string did not work.
	- The heading ("h") header/footer string did not always
	  match the first heading on a page.
	- The header and footer fonts were not used when
	  computing the widths of the header and footer strings.
	- The Windows distribution did not create the right
	  shortcut for the Users Manual in the Start menu.
	- The command-line code did not accept "--grayscale",
	  only "--gray"
	- Multi-file HTML output did not use the right link for
	  the table-of-contents file if no title page was being
	  generated.
	- Extra whitespace before and after tables has been
	  eliminated.


CHANGES IN HTMLDOC v1.8.3

    NEW FEATURES

	- New "--browserwidth" option to control scaling of images and
	  tables that use fixed pixel widths.

    CHANGES

	- The configure script now looks for the OpenGL library
	  (required if you use a shared FLTK library with OpenGL
	  support.)
	- Increased the max number of chapters to 1000.

    BUG FIXES

	- Page break comments didn't force a paragraph break.
	- --no-toc prevented chapters from being output in PS
	  and PDF files.
	- Filenames didn't always get updated properly when doing a
	  "save as"...
	- Fixed some more leading/trailing whitespace problems.
	- Wasn't freeing page headings after the document was
	  generated.
	- Wasn't range checking the current chapter number; now
	  limits the number of chapters to MAX_CHAPTERS and
	  issues an error message whenever the limit is exceeded.


CHANGES IN HTMLDOC v1.8.2

    NEW FEATURES

	- New "setup" program for UNIX software installation.
