January 30, 2010: New pre-release executable available!
Updated pre-release of ASV (version 2010/01) is now available for download to all ASV 5 customers at their assigned download locations.

General Notes
This version is much better than ASV 5.28, latest official version. (Our pre-release versions are very stable and can be used in a production environment).
There will be monthly ASV updates until official release.
Please report any issues to us. Please describe the issue with detail and if possible attach necessary files (FLA, SWF, AS...) needed to reproduce the problem. For decompile bugs, it will be great if you can attach the original source if available.

Release notes for Pre-release 2010/01
Lots of bugs fixed.
AS3 non-ANSI to ANSI convert option internally redesigned, works much better.
Embedded file search (and select SWF dialog) re-designed.
For AS3, there is new 'View Symbol Classes' command in Utility menu.
For AS3, string search (and replace) is now possible using 'View/Edit Actionscript Constants' command.
Executable name is now simple 'asv.exe'. INI name is also 'asv.ini' (rather than 'asv6.ini').

December 23, 2009: New pre-release executable available!
Updated pre-release of ASV 2009 (formerly ASV 6) executable is now available for download to all ASV 5 customers at their assigned download locations.

Release notes for ASV 2009/12 PR:
Since official release is delayed, we are providing yet another 'refresh' to ASV 5 users. And, we have decided to continue providing updates until official release.

This version is much better than ASV 5.28, latest official version. (Our pre-release versions are very stable and can be used in a production environment).

This version fixes many issues with AS2 and AS3 decompile engines.

For AS3, dark background options now available at File | Preferences, Decompile tab, AS3 Only tab, Display section.

For AS3, we have added 'Eliminate dead code' option. This option helps bypassing very simple obfuscations. Leaving it checked should not cause any trouble and should only minimally increase decompile time.

Again for AS3, we have added a command to convert all non-ANSI characters to ANSI characters, to Utility menu. This, obviously ruins any text which normally uses non-ANSI characters, but helps understanding scripts with obfuscated identifiers more easily (Let us know if you'd be interested if this command also supported AS2).

Still the name 'ASV6' is used, probably for the last time.

April 30, 2009: New pre-release executable available!
Updated pre-release of ASV 2009 (formerly ASV 6) is now available for download to all ASV 5 customers at their assigned download locations.

April 2, 2009
We are aware that ASV update is delayed. We will either update the pre-release, or, release next version of ASV in April.

January 1, 2009: Happy new year!
We wish you a happy, healthy and wealthy 2009!

Also, effective immediately, we have changed the upgrade policy for ASV. Now, when you purchase ASV, you'll get 18 months of updates/upgrades for free. Prevous purchases are not affected (and free updates they get will be at least 18 months).
