Changes in V. 0.2.2 release  of October 31, 2004:



- Large portions of the cache handling code

  reworked.  This gets rid of several wrong

  warnings about not found files (mostly due to

  login pages for forums).



- Image width/height are saved in the disk cache

  now, this reduces reformat flickering on

  re-visited pages to the nearly absolute minimum

  (#0133).



- The window handling code also got a large rework

  to have non-modal dialog windows in the future.

  As a little gimmick the F10 key does the same now

  as the F11 does in Mozilla/IE.



- An ugly hack was added to get yahoo's buggy

  standard login working (the non-ssl version).



- CTRL-V can be used now to paste text from the

  clipboard into formular input fields.



- Named character recognition added for

  apostroph.



- More types of corrupted jpeg image data are

  catched now, instead of aborting.



- Improved detection of system type (AES + kernel),

  now XaAES is recognized also.  This also allows

  to get rid of the window fuller bug with XaAES

  (#0150, #0167).



- Some error messages are displayed by alert boxes

  now instead of console output or simple writing

  to the screen



- Workaround added for weird <base href=...>

  constructs, where the complete document path is

  used as the base (wrong usage that is, but also

  used by the W3C staff!).



- Additional filtering method to detect images

  that has a particulare directory name in their

  URL.  This method is used if the search pattern

  starts with a '/'.  Eg.

     RESTRICT_HOST I /ads/

  matches all images that has '/ads/' somewhere

  in their path.



- Bugs #0133, #0148, #0150, #0167, #0169, #0170,

  #0176, #0177 resolved.

  lost when more than one was defined.

  dialog box was opend for an empty page window.

  of unknown size, reduces flickering caused by

  redraws a lot.

- Improved handling of cells with percentage width

  inside tables without any width set.

  used now over subsequent sessions, not anymore

  forgetting everything after program end.

  extents (#0100).



- Meta tag 'http-equiv=expires' implemented.

  resolved.



__________________________________________________

Changes in V. 0.1.5 release  of October 24, 2003:



- Enabled loading and displaying of image files

  over remote connections.

  NOTE:  This will only work when the CACHEDIR is

  defined properly in HighWire's cfg file!!!



- New config keyword added to control how much

  memory shall be used for caching of image

  bitmaps in memory (not those on disk):

    CACHEMEM = <kilo bytes>

  When not defined 100k will be assumed.

  (see example.cfg\highwire.cfg for details).



- Added more functionality for dithering and

  displaying of images, especially for GrayScale

  and TrueColor.



- Implemented support for 32k colours screen mode.



- Support for jpg and png implemented.



- Decreased a bit flickering of image rendering,

  by improved cache prefetches.



- Fixed the cache screwing up bug which occured

  leading to an infinite loop.



- Corrected cache size calculation for disk cached

  objects (#0126).

  protocol was given in the URL of the button bar

  (in fact, when neither a leading '/' nor any ':'

  was found there) (#0093).

  prevent HighWire from hanging due to not

  responsing servers.



- Fixed a bug occuring with both rowspan and

  colspan defined in one table cell (#0119).



- Fixed the 'too many open files' bug, resulting

__________________________________________________

Changes in V. 0.1.4 release  of August 10, 2003:



- Implemented disk caching of text/html files from

  remote (only per session yet).  To enable this

  feature the highwire.cfg file needs to include

  the line

    CACHEDIR = <path>

  where <path> must be a valid and writeable

  directory.

  background colour for pages that doesn't define

  any:

    DFLT_BACKGND = <colour>

  (see example.cfg\highwire.cfg for details).

  loading to be stopped.  The same function is

  implemented for the escape key now as well.

  Additional there is also a new button for open

  file now.

  due to frames that are loaded from a different

  server than the frameset.  Furthermore slider

  job queue.



- Bugs #0092, #0114 resolved.



__________________________________________________

Changes in V. 0.1.3 release  of June 05, 2003:



- Implemented handling of shift + left/right

  cursor keys (page-wise horizontal scrolling).



- Double clicks on arrows of sliders are handled

  now in the same way as N.AES does (for left and

  right mouse button).



- New menu entry (under 'Options') to have frames

  always resizeable and scrollbars if necessary,

  even if the HTML defines anything else there.

  The default is off but can be set to on with the

  keyword FORCE_FRAMECTRL = 1 in the config file.



- New keyword FONT_MINSIZE to define a minimum

  font height in points, eg. for <font size=1>

  (see example.cfg\highwire.cfg for explanation).

  frame size values, makes it much more robust

  against faulty frameset tags.

  and after lists.

  colspan and rowspan set.



- Re-implemented <div> tag rendering to tables

  with one single cell, matches their meaning much

  more now than the previous implementation.



- Added resetting of font characteristics after

  tables and title tags, this was messing up the

  renderer while calculating text word widths

  (only rarely seen on some very simple pages).



- Set texts of buttons and input fields always to

  black.



- Removed several code redundancies.



- Bugs #0041, #0096, #0098, #0102, #0103, #0104,
