Important

If you use Windows Defender, it may incorrectly flag this version as malware. SmartScreen may also do this. Don't worry; this is safe to download and use.

This AV solution flags this program because it lacks code-signing certificates, which are quite expensive (as of January 2025, 660 and 864 dollars for 3 years of SV and EV certificates, respectively, from Comodo).

If you use other antivirus solutions, you will not see this problem. Learn more here

Compared to earlier preview releases, this preview release is a small one. This is because work went into adding special features to some components for the release of the next version, 0.8.1 (stay tuned for these features, you will love them!). Also, work went doing some under-the-hood changes.

Bugfixes

No issues were fixed in this release.

New features

• In portable installations, file associations can now be toggled for the Starter Script Editor
• The DynaLog log viewer has received support for event log filters
