What's new in this version:

- This new version supports very large files in the Free version as well as the Professional version. I believe this will benefit many students at school and home, who need free text editors supporting very large files. What I mean by “very large file support” is the ability to open very large files without loading all contents into the memory. EmEditor will read a file directly from the disk if the file size is larger than 300 MB by default. For a long time, the file loading has been optimized for speed by using multithreaded code using SIMD instruction sets. In other words, EmEditor Free opens very large files as fast as EmEditor Professional. Even though EmEditor Free supports very large files, the Large File Controller is available only on EmEditor Professional. Please see EmEditor Free for the updated comparison table.
- The main feature of v21.3 is a new date/time support in Number Range expressions. The feature was requested by several customers including this question. For example, when you analyze server logs or sales reports containing dates/times, you often want to focus on a certain date/time range, and the new feature becomes useful in these situations. You could use regular expressions to search for a certain date range, but regular expressions often become complicated and slow. Thus, I’ve decided to support date ranges in existing Number Range expressions. When I developed this new feature, I wanted to make sure it would be optimized for speed. I also understand that you want to take full control over which date format you would want to match. Therefore, the date expression allows you to specify a date/time format surrounded by double quotation marks
- You may also use month names such as “January” or “Jan” by using “MMMM” or “MMM”, respectively, or use 24-hour time format: “HH:mm” or “HH:mm:ss”.
- The new date range feature is available both in EmEditor Free and in EmEditor Professional.
- Other new features include the ability to split a window into 3 panes! This feature has been requested for a long time. To split a window into 3 panes vertically or horizontally, select Split Vertically or Split Horizontally on the Window menu twice. This new feature is included in EmEditor Free and EmEditor Professional.
- A customer wanted to move the current cell selection to the right when you press the ENTER key while in the CSV Cell Selection mode in EmEditor Professional. Previously, EmEditor can only set the focus into the Cell toolbar when you press ENTER. The new version allows the ENTER key customization, and introduces 4 new commands including the Next Cell (Cell Selection Mode Only) command. Thus, you can assign the ENTER key as the Next Cell (Cell Selection Mode Only) command.
- A customer requested the ability to change the font size used in dialog boxes. While it is not easy to change the font name, it is relatively easy to change the font size. So, the new version allows you to change the font size in the Window page of the Customize dialog box. Another customer using the Chinese UI requested the ability to change the font face name. EmEditor’s dialog boxes use MS Shell Dlg, which is automatically substituted with an appropriate system font in each language of Windows. The font substitutes are defined in the Registry key: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionFontSubstitutes. The issue is that this substitution table is old. I’ve learned that the old SimSun font was used in Simplified Chinese Windows by default, but it isn’t easy to read. While modern fonts like Microsoft YaHei are used in Windows and even recommended by Microsoft, the font substitution table still points to the old font, which is not updated even now. I thought that Microsoft forgot to update the font substitution table, but maybe they worry about compatibility issues with older apps, so they intentionally didn’t update it. We have decided to hard-code Microsoft YaHei for Simplified Chinese, and Microsoft JhengHei for Traditional Chinese. We have not changed the other language UI yet but will test the other languages in beta versions for the next version. We will use Meiryo UI for Japanese, Malgun Gothic for Korean, and Segoe UI for other languages. We will release beta versions soon, so please try the new beta versions with the new dialog boxes when they become available, and let us know if you like the new look and feel.
- Latest updates of Windows 11 include bug fixes that I have previously mentioned. I have tested EmEditor on Windows 11 thoroughly, and I don’t see any issues with EmEditor on Windows 11 anymore except that some plug-in dialog boxes don’t look good on the Very Dark mode. The dark mode is still undocumented for desktop apps, and I am still looking into the issue. Unless you use the Very Dark option of EmEditor, there are no issues with EmEditor on Windows 11.
- Finally, I hope you like EmEditor, whether you use the Professional or Free version. Please contact us or write in forums if you have any questions, feature requests, or any ideas in the future. I also welcome you to write a review by selecting the Write a Review command on the Help menu, because I read them periodically. (You might need to download the Store App version before you are able to write a review.)
