<title>What's New in Recent Versions</title>
<body>
<h1>What's New?</h1>
Things of note which are new in this version:
<ul>
<li>Image sizes should be calculated better in non-square modes, so imagemaps will work better
<li>Hot keys are detected on <select> menus and are not right justified by the Wimp any more.
</ul>
New in recent versions:
<ul>
<li>Multithreading fixed so that structures belonging to one thread don't get
deallocated by others whilst the other is still actively using the structure.
<li><a href=bugreports>Debug information</a> sent to RAM:$.WebRegs if DumpRegisters variable is set.
<li>A lot more information in the <a href="arcweb">user manual</a> pages.
<li>Other misc fixes
<li>Massive bug in message reception function fixed. This would have caused
random Address Exceptions.
<li>Anchors work again - they were broken in 1.27 and possibly before that too.
<li>RISC OS 3.1 should no longer die when I delete windows due to the WindowManager
bug. I have added code to defer window deletion until the Wimp does not have
any icon slabbed in.
<li>Nothing was being automatically run (even 'safe' types) due to me failing
to read the top of PRM 1-310 regarding the fact that <tt>os_read_var_val</tt>
<em>can</em> return an error, even if it succeeds.
<li>gopher code rewritten to handle EOL correctly
<li>Bug in email handling (caused a crash) fixed
<li>Mouse pointer changes shape whilst over a hyperlink
<li>spurious window openings and crashes when using dialogue boxes have been
fixed (bug in RISC_OSlib)
<li>History window has a menu to allow you to flush it
<li>Won't open archives automatically, but will force you to save them before
opening. This is a security feature as much as anything else
<li>More modules included in the !System directory
<li>The low memory handler contained a massive bug which resulted in the render
of a page stalling if there wasn't enough memory for an image conversion.
This could quite possibly have caused other weird errors for people who ran
low on memory.
<li>Accepts data files and DOS files, thus making browsing structures inside TAR
archives possible again.
<li>This version shouldn't be killed by ImageFS² so easily, and if the
option in the Choices file is set up (no GUI interface to this option yet),
it will attempt to use ImageFS² to perform it's image conversions.
<li>FTP and gopher clients multitask better
<li>HTTP client more tolerant of unfortunately packet splits on slow networks
which should stop you seeing the HTTP headers on pages.
<li>Lots of miscellaneous little fixes
<li>When delayed image loading is on, you can click on the little sprite icon
to reload the page with images
<li>Recompiled version of PrintWeb to use new flex library - it now handles
multiple drawings in succession OK for me, plus WimpSlot increased.
<li>Module ensuring is modified to allow RISC OS 3.6 users to carry own with
their ROM versions and not load the bugfixed newer versions.
<li>Major resource leakage in icon bar handling code fixed. If you ran
<img src="#!help" alt="!Help"> and left the pointer over ArcWeb's icon,
then the wimpslot goes up and up and up until it quits with the error
<tt>No more windows</tt>.
<li>Shy window problem should be cured (again!)
<li>New history icon by Pfert.
<li>New options in Network window to send Referer and From headers
<li>Fix to parser regarding nested tags
<li>FORM posting is fixed (was broken in 1.17)
<li>Page fetching is terminated correctly so you don't get a dead spider on
the icon bar icon
<li>Page fetching fixed so you can View Source of local: pages again. This was
broken in 1.17 and will affect any local: pages you may have viewed with
version 1.17. Fix is to flush the cache.
<li>Added option to open the Helper directory from the Show menu
<li>You can add things manually to the hotlists on the Hotlist window menu
<li>You can open the global history list from the toolbar
<li>You can force inlined images for a page to be fetched by clicking on
the appropriate toolbar icon.
<li>Toolbar icons rearranged into groups representing similar features
<li>History code works! The availability of previous and next pages in the window
history is reflected by the availability of the toolbar icons. They will be
greyed out if you cannot go that way.
<li>SHIFT-Click on a hypertext link will force a save box to appear for the
object pointed to by that link
<li>Font configuration window
<li>Colour configuration window<p>
This is implemented as a seperate application. It is a Toolbox application
which takes advantage of facilities provided by the Toolbox for colour
editing. Since it requires several modules specific to the Toolbox, they are
included in the supplied !System:
<ul>
<li>System:Modules.310Support.ThreeTen (<em>for RISC OS 3.1 only</em>)
<li>System:Modules.Toolbox.Toolbox
<li>System:Modules.Toolbox.Window
<li>System:Modules.Toolbox.ColourDbox
</ul>
<li>Each Acorn division has its own link on the default home page
<li>DNS resolver now has a cache, so network things should be a lot faster
</ul>
