We’re excited to announce the release of EmEditor v24.5.0. We strongly recommend all users update to this new version.

Many users depend on EmEditor for managing large files daily, so ensuring seamless opening, editing, and saving is essential. However, from versions v22.4.0 to v24.4.1, there was an issue where file sizes could increase when reopening large files (around 300MB or more) from certain hard drives, even though the first opening was fine. This was reported by a customer, and we appreciate his feedback and apologize for any inconvenience. This issue didn’t occur with fast hard drives like SSDs, but on slower drives with disk cache enabled, duplicate lines could appear. We fixed this in v24.4.2. In v24.5, we’ve added code to prevent such unknown issues by showing a message if there’s an internal file size inconsistency. Therefore, we strongly recommend all users update to v24.5.

Additionally, v24.5 introduces a new Verify command in the File menu. By selecting this command right after opening a file, you can save the current document as a temporary file and compare its size and SHA256 hash value with the original file.

The results are displayed in the File Verification Results dialog box, and you can copy the size and SHA256 hash value. Normally, the original and temporary files should match in size and hash value. However, discrepancies might occur if the original file contains NULL or invalid characters, or if there are hard drive or memory errors. For important files, please use the Verify command immediately after opening to ensure everything is correct.

We’ve also added an option in the File page of the Customize dialog box for automatic verification every time a file is loaded.

The new version (v24.5) also includes several other features, many of which were requested by users.

When dealing with large files, it can be convenient to open only a smaller section and navigate to the previous or next section by clicking a button. This was suggested by a customer. In v24.5, we’ve added << and >> buttons to the Large File Controller, allowing you to move to the previous or next section within a specified size range.

We’ve improved the AI-assisted writing feature by expanding the options available with the OpenAI API, which was initially introduced in version 24.1. Previously, suggested text would automatically appear in gray as you typed. Now, you have the option to display suggestions only when you press Ctrl+Space, which helps reduce the frequency of OpenAI API calls. If you prefer the automatic display of suggestions like before, they will only appear when the AI’s suggestion meets a certain confidence threshold, which you can now adjust. For instance, if you set the confidence to 40%, the AI will show suggestions only when it predicts the next text with at least 40% confidence. To minimize suggestions from less certain predictions, you can set a higher confidence, like 80%, ensuring that suggestions are shown only when predictions are more reliable, thus reducing the number of OpenAI API calls. Additionally, we’ve added options to adjust the length of the input text used for predictions and the output text for candidate suggestions. Using longer input text for predictions increases accuracy but also raises the OpenAI API usage fee. Similarly, longer output text results in more words being suggested.

Moreover, based on a request from a customer, we’ve made it so that pasting in the Chat with AI window won’t immediately send the message.

Bugs found during the preview version development have been fixed.

Finally, while EmEditor requires an internet connection for product activation, some environments need a proxy for internet access. In this version, we’ve added a Proxy Settings link in the Register Product dialog, enabling you to configure proxy settings easily. The desktop installer now includes a PROXY option for command line installation.

Today, we are releasing EmEditor v24.4.1.

v24.4.1 includes the following bug fixes. Please make sure to always update to the latest version for stable operations.

• Fixed the issue of freezing and crashing during document comparison that occurred in v24.4.0.
• Resolved the problem where bold text was not displayed even when the “Highlight Matching Brackets” option was enabled in v24.4.0.
• Fixed the display position of bookmarks and change line indicators in the Markdown design view in v24.4.0.
• Addressed a potential crash issue with the OpenDocuments plugin.
• Reduced the likelihood of crashes due to memory shortage when undoing after replacing all instances including newlines.
• Fixed display issues that occurred when changing line wrapping methods during document comparison.
• Improved crash reports.
• Addressed customer reported issues (1, 2, 3).

Today, we are excited to announce the release of EmEditor v24.4.0.

The main feature of the latest version (v24.4) is improved Markdown support, introduced in response to customer feedback (1, 2). It includes the new Markdown Design View that offers a near-WYSIWYG experience.

Markdown, introduced by John Gruber, is widely used across various platforms due to its simple text formatting capabilities for paragraphs, links, and images. Documents in Markdown are easily readable even in basic text editors like Notepad, making it popular for blogs, StackOverflow, Wikipedia, and academic papers. Recently, it’s also been used in AI-generated responses. The enhanced Markdown support aims to improve the display of AI prompt responses, a feature introduced in the previous version (v24.3).

A Markdown Design View button has been added to the main toolbar, allowing you to toggle the Design View on or off. When you select the Markdown configuration, opening associated files will automatically enable the Design View. This view is also applied to documents created using the AI prompt feature. You can adjust these settings on the new Markdown page in the Customize dialog.

Switching to the Design View displays the Markdown toolbar. By clicking the Markdown Preview button, you can view a preview of the Markdown using the WebPreview plugin.

Here are some key differences between Markdown Preview and Design View:

• You can edit in Design View, but not in Preview.
• Images appear in Preview, while they’re represented as emojis (🖼) in Design View.
• Line breaks in the source text may not be preserved in Preview, but they always appear as line breaks in Design View. Hard line breaks in the source text are marked with emojis (⏎) in Design View.
• If table headers are missing in the source text, they are hidden in Preview but shown as empty headers in Design View and can be edited.
• Code and regular text are displayed in different fonts in Preview, but in the same font with different colors in Design View.
• Specified languages in fenced code blocks are highlighted in Design View according to the language configuration.
• HTML tags, character references, and numeric character references in the source text are displayed correctly in the Preview, but they do not appear in the Design View.
• Heading lines are displayed in the correct font size in the Preview, but in the Design View, they are always shown in the same font size if DirectWrite is not used. By default, the settings use DirectWrite, so this should not be an issue.

Given these differences, it’s advisable not to rely solely on EmEditor’s Design View. Instead, check your work in Preview or an external web browser during editing.

You can change block styles using the dropdown menu on the Markdown toolbar, like Paragraph, Heading 1, Heading 2, etc. You can also format text with buttons like Bold, Italic, Code, etc. These buttons behave differently depending on whether text is selected or already formatted. For example, clicking Bold without selecting text will bold the entire word at the cursor. If the text at the cursor is already formatted differently, only that text will be bolded. Clicking Bold with text selected toggles the bold formatting. Other buttons allow you to create/insert links, images, tables, horizontal lines, line breaks, numbered lists, bullet lists, etc. These commands are also accessible from the Markdown submenu of the Edit menu, with Ctrl+B as the shortcut for Bold.

There’s still room for improvement in the current Markdown Design View. Some users might notice discrepancies between Design View and Preview. For complex edits, Design View might not be ideal. For instance, adding characters at the start of a heading could change it to a regular paragraph. In such cases, it’s better to disable Design View for editing. It’s also quicker to edit source text directly when changing image or hyperlink paths and titles. However, EmEditor isn’t meant to be a full-fledged Markdown editor. Markdown’s strength lies in its readability, even in plain text. We hope you get comfortable toggling Design View on and off as needed.

For parsing Markdown syntax, a modified version of MD4C (Markdown parser for C) by Martin Mitáš is used. MD4C follows CommonMark, which EmEditor also uses as a reference. However, EmEditor supports tables not specified in CommonMark.

The new version (v24.4) also includes several other features, many based on user requests:

• The display of differing lines in comparison results has been enhanced; similar lines previously grouped as added lines are now shown as changed lines.
• The Copy All to Other command now closes the source document.
• Onigmo.Perl has been added to the list of regular expression engines, with Onigmo now called Onigmo.Ruby.
• The Find/Replace dialog’s multi-line boxes now support automatic line wrapping.
• Menus hidden when the window width is reduced can now be accessed via keyboard shortcuts. For example, the Macros menu, accessible with Alt+M, is usable even in a small window.
• The /ola command line option has been added, allowing offline licenses to be saved for the entire computer with admin privileges.
• Bugs found during the preview version development have been fixed.

We hope you enjoy using EmEditor, whether you choose the Professional or Free version. Please contact us or write in our forums if you have any questions, feature requests, or suggestions.

Thank you for using EmEditor!
