Changes in this release (from the author):

After 500 builds of the 2.9 release, it seemed like a good time to change to 3.0.

Code signing: the big news with this release is that dnGrep releases are now signed with a code signing certificate provided by, certificate by SignPath Foundation. A big thank-you to SignPath for their support of open-source software.

Starting with this 3.0 release, you will no longer get the "Unknown Publisher" warning from Windows. However, at least initially, you will see and almost identical Microsoft Defender SmartScreen warning for an "unrecognized app". Click the "More info" link, you should see the publisher as SignPath Foundation (if you don't see SignPath as the publisher, don't install it), and then you can click the "Run anyway" button. With the code signing certificate, the application has to gain reputation before this warning is not shown any more (i.e. installed by a threshold number of users, there is no official documentation on how this works exactly). And since the application reputation is associated with the certificate, this process will be repeated in three years when the certificate is renewed.

The dnGrep install kits and the application binary files are signed. The signed files mean the code you see in GitHub is the code built on AppVeyor, scanned for malware, and signed on SignPath. Code signing is applied only to dnGrep project code in the dnGrep GitHub repository release branch and built on AppVeyor. The dnGrep install kit contains third-party libraries used by dnGrep, which may or may not be signed.

Other changes:

The Chinese (Traditional) translation has been added. Other translations have been updated, thank-you to all the translators. See here if you want contribute to the translations.

Issue #612 PowerPoint search: the OpenXML plug-in has been enhanced to also search in PowerPoint files.

Issue #614 Validation color: the validation messages for Regular expressions, XPath and Byte search patterns have been colored on dnGrep's main window, as there are on the test window.

Issue #615 Byte search test expression: the Test window has been enhanced to include testing Byte patterns.

Issue #616 Bookmark sections: the dnGrep bookmark feature has been enhanced to allow disabling parts of the bookmark. Over time the number of properties stored in the bookmark as grown, and previously all bookmark properties are applied when the bookmark is used. With this change, the bookmark has been split into three sections of file source, file filters, and content search. By default, all three sections are enabled. But you can edit each bookmark to enable or disable each of the three sections.

Issue #617 Icon refresh: the dnGrep application icon and images have been updated thanks to a contribution from @Mr-Administrator

Lastly, I am planning update the .NET build version used by dnGrep to .NET 4.8, which has long term support on all versions of Windows. Most users are probably already have the .NET 4.8 runtime installed, but if you think this will be a problem for you, please comment using the Join Discussion button below.
