IDA Pro 5.5 and Hex-Rays 1.1 have been released!

IDA Pro 5.5

We are happy to announce a new version of IDA Pro! The major news is the
new docking user interface. There are many other improvements: processor modules,
file formats, analysis tweaks, well, the usual stuff. There is a new MS Windows
Crash Dump Loader and improved Bochs debugger. The complete list of new
features and bug fixes is available here

Hex-Rays 1.1

We also release a new version of our decompiler: now with the floating point
support. It was a technically challenging task and required lots of testing, but
we are very happy with the end result. It can really handle floating point
computations and generates reliable output. All subtle nuances, like conversion
rules, fpu stack state, predefined compiler helper functions, are all taken care of.

The decompiler uses debug information if it is available: in this case, even local
variable names and types will be restored. If there is no debug information, the
decompiler will still generate correct and precise output. In fact, it is designed
to work without debug information, which means that virtually any
compiler-generated executable can be analyzed and turned into C output.

New pricing and support plans

With this release, we update the pricing of IDA Pro and Hex-Rays Decompiler.
While the initial purchase prices are increased, upgrade prices go down.
In order to streamline the upgrade process, we will use the same rules for
all our products: now a support plan is renewable any time while it is active
and also three months after its expiration. The new support period is counted from
the expiration date of the previous support period.

If you upgraded your IDA/Hex-Rays copy the last month with older prices,
do not worry. For you, we will add a month of support for the IDA license,
and three months of support for Hex-Rays Decompiler.

We will continue to accept old-style upgrade orders until 12 October 2009.

How to request the new versions

As usual, the new versions are free for users whose licenses are within active
support plan. Submit your ida.key to

and expect a message from us within 5-10 minutes. Sometimes we do not have your
email in the database, so please specify it (otherwise we will have no means of

Is your key too old?

If your key is too old for a free update, you might still be
eligible for a discounted upgrade. Until 12 October 2009 we offer the upgrade
prices for all purchases made two years ago or less. The order forms can be

That’s all folks! Enjoy the release.
