Release notes from dnGrep

v4.7.10.0

2026-03-10T23:58:46Z

Changes in this release:

Note: The .msi kits in this release were built with updated installer tools. They should work the same as the previous kits, with one exception:

If you want to downgrade to a 4.6 or earlier release after installing the 4.7 or later release, you must uninstall dnGrep before installing the old release. Normally the installer requires you to uninstall the later release before installing the earlier release, but the old installer kits do not detect the new 4.7 installation.

#1389 ARM64 Release: This release contains an experimental or prerelease ARM64 build of dnGrep.

The .msi and zip packages have not been tested because I do not have access to an ARM64 system and could not create an ARM64 VM on Azure. If you have an ARM64 system, please try them and report any issues.

#1431 Tab and Whitespace: Improve tab/whitespace rendering and match highlighting

Update whitespace rendering to align tabs/spaces visually, using column tracking and dynamic padding.
Set Preview window indentation size to match tab visualization.
Enhance Word Reader to handle TabChar.
Update match highlighting to use visual columns for accurate alignment.

#1432 Exclude Context Lines: Fixed a bug copying text from the Results tree. Context lines were included even when the show context lines option was disabled.

#1439 Support Everything 1.5a: Added support for the 1.5a release of Everything. See Configure Everything to use either Everything 1.5a or 1.4.1.

#1441 Encoding bug: Fixed a bug in the Replace Preview window where the "new" text has the wrong encoding.

Release includes:
.NET 9.0.14

v4.6.110.0

2026-02-12T00:19:32Z

Changes in this release:

#1399 Search in Options: Added a 'Find' box to the top of the Options dialog to search for text in the options. Ctrl+F will take you to the find box. The search text will be highlighted in the dialog and scrollbar. You can jump to the next and previous matches with the F3 and Shift+F3 keys. Also added the shortcut keys Home, End, Page Up, and Page Down. There is a known issue that won't be fixed: if you do a search and then change the language setting, the text that had been searched will not change to the new language until the dialog is closed and reopened.

#1421 View Whitespace Made a change to View Whitespace in the results tree: if the whitespace is an ordinary space, it is shown as a small dot. If the whitespace is non-breaking space or another whitespace character, it is shown as a small circle.

#1426 Window Title Bar Added a new setting to the dnGrep theme files to set the window border thickness and fixed some layout issues. The window border thickness defaults to 1, and the is no visible difference between dnGrep being the active window or inactive. If the border thickness is set higher, the active/inactive border color is shown. Existing theme files do not need to be updated unless you want to increase the border thickness. See the issue for the new theme setting, a screenshot, and a sample theme file.

v4.6.95.0

2026-01-14T00:37:43Z

Changes in this release:

#1394 Work with password protected files Added options to open password protected PDF and archive files. These are disabled by default and can be enabled in the 'Archive' and 'PDF to text' sections of the Options dialog. dnGrep will cache the passwords for the current session only; it will not save them anywhere. The extracted text from password protected PDF files will also be cached for the current session only and deleted when exiting dnGrep.

#1396 Copy to search and copy to replace In addition to the swap search and replace added in v4.6.52, this release adds 'Copy search for to replace with' and 'Copy replace with to search for' actions.

#1401 Bug fixes Fixed a bug in the String Map when including a tab character (U+0009) in the map.
Also in the String Map dialog, changed the Substitute character input field to update the Unicode code point like the Original character input field.
Added context menu commands to arrange the lines the String Map dialog: Move up, Move down, Move to top, and Move to bottom. There are default shortcut keys: Alt+Up, Alt+Down, Shift+Alt+Up, and Shift+Alt+Down, same as is in the Bookmarks dialog.
Added 'Show whitespace' to the main window results tree controlled with a checkbox in the bottom tree control panel.
Fixed a bug in changing the match highlight color in the Preview window when the application theme is changed.

#1405 Shortcut key requests Added new commands so users can assign shortcut keys to them: 1) 'ToggleExpandAll' command will expand all results if they are all collapsed and collapse all results if any are expanded. 2) 'ShowLinesInContext' command will toggle the Show context lines checkbox to hide or show context lines in the results tree.

v4.6.52.0

2025-11-11T19:22:06Z

Changes in this release:

#1328 Flip Search and Replace: Added a button to switch the search and replace strings

#1359 String Replacements: Added a new feature to the plugins to replace special characters when the text is extracted from the document file. For example, you can replace non-breaking spaces with normal spaces to make searching the text easier. There is some additional time required to do the replacements, depending on the number of replacements and size of documents. The feature is disabled by default - enable it in the Options dialog in each plugin configuration. At the top of the plugin configuration section is a button to configure the string substitutions. You can define replacements to replace a single character or multiple characters such as ligatures or combining characters. The initial values include non-breaking space to space, non-breaking hyphen to dash, EN-dash to dash, left double quote to quote, and right double quote to quote. You can enter characters by keyboard, copy/paste, or entering Unicode code points with the U+ hex code format (see examples). Add a space separator when entering multiple code points.

#1373 Search Result bug: Fixed a bug in the search result tree that was repeatedly scanning the files for the file read-only flag. This caused the tree to be unusable when the search results included thousands of files on a network file share.

v4.6.7.0

2025-11-05T01:44:35Z

Changes in this release:

#1349 Error copying search results Fixed a bug in copying the search results when the matching text in the result contains a newline.

#1340 Command Line Added new the command line options for Everything and searchFor. The new option keys add an asterisk to the key name to enable taking the option value verbatim without need to add additional quotes or escape characters. When in verbatim mode, the option must be the last option on the command line. If both Everything and searchFor are in verbatim mode, they must be the last two options on the command line, and the last option key must use the long form of the key, either -everything* or -searchFor*. This feature has been available for Everything since v4.2.6 (May 2024) but without using the asterisk modifier. The asterisk modifier has been added to the Everything options for consistency, and the keys without the modifier (this is a breaking change) work like other options, and do not need to be at the end of the command line. Here is an example of verbatim mode, note the regular expression to search contains quoted patterns and both option values include spaces.

"C:\Program Files\dnGrep\dnGREP.exe" -st Regex -searchFor* "p\w*" "r\w*" -everything* c:\temp\testData *.cs

Syntax:
Normal mode: you must add quotes if the value contains a space, and the value cannot contain a quote character.

  /s [string]
  -s [string]
  -searchFor [string]
  /e [string]
  -e [string]
  -everything [string]

Verbatim mode: do not add enclosing quotes, and the value may contain any character.

  /s* [string]
  -s* [string]
  -searchFor* [string]
  /e* [string]
  -e* [string]
  -everything* [string]
