Internet Explorer 5.5 began testing in late October alongside a new
networking DUN technology code-named "Mars" which will
also be included in Millennium. The current release, a so-called
"Platform Preview," is designed for developers, not end
users, making this release unsuitable for most people (A beta one release is expected in Q1 2000 that will be more
appropriate for end-users). And like Internet Explorer 5.01, IE 5.5
is not a major new release of the browser suite. It is designed to
fix bugs (of course), add new developer features, and it includes a
new Print Preview feature that is the single high-profile addition
to the package. In short, it's evolutionary, not revolutionary.
Bug fixes
While Microsoft has not published a list of the bugs fixed in IE
5.5, mostly because of the product's early development status, you
can be sure that it will include all of the bug fixes in IE 5.01 and
more. Hopefully by the time IE 5.5 ships in mid-2000, Microsoft will
be able to claim that it has a reasonably secure product to offer
customers.
Print Preview R Us
Internet Explorer 5.5 is the first version of Internet Explorer
to support Print Preview (Image), which allows you to work with an
Office-like preview of the page(s) that are to be printed. You can
specify header and footer text for the documents, zoom in and out to
preview the document as it will be printed, and perform any other
features you're used to in, say, Microsoft Word. Essentially, Print
Preview eliminates the guesswork when printing from the Web. Not a
huge deal, but it's nice.
Web developer features
Aside from the bug fixes, which, let's face it, are the real
reason for this release, Microsoft has snuck some new functionality
in for Web and software developers as well. I'm not sure I
understand the point of this, to be honest, since its hard enough to
ensure that users are using a certain browser, let alone a certain
point release as well. In any event, Microsoft has seen fit to add
the following new Web developer features to IE 5.5:
Better
support for the Cascading Style Sheet (CSS) standard, including
the first-letter and first-line pseudo-elements
I'm not going to
waste too much time on this stuff for obvious reasons. For more
information about IE 5.5's developer features, please visit the Microsoft
MSDN Web site.
Getting IE 5.5 Platform Preview
Windows 95, 98 and NT 4.0 users can download the IE 5.5 Platform
Preview now from the Microsoft Web site. It utilizes an Active Setup
program that is very similar to previous versions of IE 5. Windows
Millennium Beta 2 users have IE 5.5 built right in; there's nothing
else that needs to be done. Windows 2000 users will have to wait
until Windows 2000 goes gold: The Platform Preview version of IE 5.5
will not install on this platform though a future version
will.
Conclusion
I don't recommend this build of IE 5.5 to any end users or
developers. For users, IE 5.5 Platform Preview is not stable enough
for daily use and it seems to prevent the use of Windows Update for
many people (this isn't true for Millennium users, however). Windows
NT 4.0 seems particularly problematic for this release, for some
reason. And I've word from many people who are unable to uninstall
this build, which is a huge problem. If you've got a single machine, especially, steer clear of
this release: All of the current bug fixes are in IE 5.01 (which
frankly has its own issues) and the Print Preview feature, while
nice, isn't enough of a reason to upgrade. Heck, it's barely enough
reason for this release to even exist.
For developers, the picture is a bit more complex. IE 5.5 is the
version of Internet Explorer that was to have ushered in a new age
of DHTML-based user interfaces ("Activity Centers"), so many of its low-level programming
interfaces were designed with these lofty goals in mind. However,
Microsoft has since reversed course and pushed back its new Windows
user interface plans to 2001 at the earliest. While developers
frequently need to stay ahead of the game by nature, the IE 5.5
Platform Preview just doesn't make sense. The Web development
improvements are relatively non-essential and the platform upgrades
are pointless since there isn't a version of Windows coming soon
that will take advantage of them. Most importantly, it will be late
2000 at the earliest before IE 5.5 has any measurable marketshare.
If you're hell-bent on staying ahead of the Joneses, spend some time
ready the documentation (link above) and wait for a later release.
For some reason, the computer industry has fostered a "gotta
have it" attitude among users who seem eager to download and
install the next big thing, regardless of the effect it may have on
their system. I caution restraint with this release, however: If
there is any market at all for this release, it is very small and
chances are you're not part of it. I'm certainly not.
