- Updated the libcurl library to the latest version to fix an issue when downloading empty files over SFTP on a reused connection. Previously, downloading 0-byte files over SFTP after listing a directory could result in the error message "Number of redirects hit maximum amount." - Web preview: On iOS 26, the debug console button now pulses when there is a new entry. On earlier iOS versions, a badge with the number of entries is shown.

- Fixed an issue on iPadOS 26 that sometimes caused the insertion point to jump to the beginning of the file when working with multiple windows and clicking in the editor with a trackpad or mouse. - Added a workaround for an issue where the editor would scroll to the top and immediately to the bottom when tapping at the top of the window on iPadOS 26.

- Fixed an issue with the web preview in Dark Mode where websites that didn’t set a background color appeared with a black background instead of white, resulting in black text on a black background. - Fixed an issue where the “…” button could be missing on iPhone after downloading the currently open file using the file transfer screen and reopening the same file. - Other minor improvements.

Added support for the Liquid Glass design on iOS and iPadOS 26. The interface is fully updated to match the latest system appearance. Includes an updated app icon and adjustments for the new iPhone Air display size. Other Improvements: - Web Preview: fixed a brief white flicker when opened in Dark Mode. - Improved naming of line ending types. - Disabled auto-pairing of single quotes in LaTeX and TeX math environments. - Other minor improvements and fixes.

- Added support for “Use Selection for Find” (Cmd-E) to quickly search for the selected text or the word at the insertion point. - Added full support for the new menu bar in upcoming iPadOS versions. - Updated some keyboard shortcuts (like “Show Sidebar”) to match system defaults. You can customize keyboard shortcuts in Settings → Keyboard Shortcuts. - Fixed layout issues with the on-screen keyboard on the upcoming iPadOS version. - Other minor improvements.

- Fixed an issue where triple-tapping empty lines at the start of a file could cause an infinite loop and eventual crash. - Fixed an issue where auto-indentation could interfere with dictation, causing it to stop unexpectedly. - Other minor improvements.

- Fixed an issue where inserting new lines while zoomed into the editor could cause parts of the editor to not be fully redrawn. - Other minor improvements.

- Fixed a flickering issue that could occur when scrolling with automatic word wrap disabled. (Present since the previous version.) - Fixed an issue where the second-to-last tab could sometimes disappear on certain iPhone models.

- Tapping the editor to bring up the on-screen keyboard now scrolls the tapped line into view if it would otherwise be hidden behind the keyboard. - Removed the redundant “Files” button on iPad, which always displayed the sidebar as an overlay. The sidebar now automatically appears as an overlay in portrait orientation on smaller devices and with small window sizes. You can still overlay the sidebar in landscape orientation using Ctrl-Option-Cmd-B or by swiping to the right. - Improved button layout on small iPad displays and with small window sizes. - Improved interactive window resizing on iPadOS and fixed flickering on future systems. - Updated the web preview chapter in the manual. - Updated the manual entry on how Textastic integrates with Working Copy. - Updated the libcurl library to the latest version. - Other minor improvements.

New: Code Formatting! You can now format HTML, CSS, JavaScript, and JSON files using the new built-in formatter based on js-beautify. Tap the (…) menu in the top-right corner and select “Format Code”, or press Cmd-Option-L to reformat the current file. The formatter is highly configurable: you can adjust line wrapping, indentation, brace style, newline handling, spacing rules, and much more under Settings → Format Code. Also in this update: - When uploading to WebDAV, Textastic now sets the “Expect: 100-continue” HTTP header to make sure a server accepts an upload before data is sent. This can prevent duplicate sending of data when the server requires re-authentication. - Fixed an issue when uploading files to cPanel WebDAV servers (cpdavd): that server closes the connection after each response instead of keeping it alive, which could result in a “request stream exhausted” error. - Moved Password Lock settings to Settings → Other: since iOS/iPadOS 18, you can touch and hold the app icon on the Home Screen and select “Require Face ID” (or Touch ID or Passcode) to lock the app. This is the preferred method since it works at the system level and also protects Textastic's local files in the Files app. - Other minor improvements.

- Fixed an issue where uploading folders to FTP/FTPS servers could fail if remote folders did not already exist. - Fixed a rare crash that could occur when closing certain very large files.

- Improved automatic closing of quotes: quotes are no longer closed after a backslash (e.g., when entering umlauts in LaTeX), and they are now properly closed before semicolons and commas in CSS files. - SSH Terminal: Added support for the Delete key (forward delete) on external keyboards. - Updated the HTML5 template and removed outdated HTML 4.01 and XHTML templates. The HTML5 template now matches what's Emmet inserts when typing "!" and hitting Tab. - HTML script tag code completion: no longer inserts the type and src attributes by default. The src attribute can be added manually or using the "script:src" Emmet abbreviation.

This update includes the following minor improvements: - Disabled Writing Tools when entering text in the SSH terminal. - Fixed an issue where “Manage Subscription” was not shown in settings when a monthly subscription was active.

- The on-screen keyboard can now be dismissed by scrolling down in the code editor. This setting is enabled by default on iPhone and disabled on iPad. You can change it in Settings -> Code Editor -> Dismiss on Scroll. - The edit menu (with actions such as Cut, Copy, and Paste) is now shown when selecting lines by tapping a line number, when choosing Select or Select All, and when using the cursor navigation wheel on iPad. - The edit menu now appears faster and more reliably when tapping the same text location twice.

Textastic is now free to download with a one-week free trial. To start the trial, new customers can choose a yearly or monthly Textastic Pro subscription. You can also unlock all features with a one-time purchase instead of subscribing. Anyone who previously purchased the app retains full access to all current features at no extra cost. Also in this update: - Added an option to disable Writing Tools (available on devices with Apple Intelligence enabled only). - Improved keyboard behavior when creating a new file on iPhone. - Fixed an issue with “Open with Encoding…” where the save alert didn’t appear on iPhone. - Other minor fixes.

Improved integration of external folders provided by the FTP Files, S3 Files, and Source Files apps: - Pull-to-refresh in external folder files lists now reliably causes those apps to fetch the latest directory contents from servers. - When switching tabs, Textastic now notifies the file provider of these apps that a file was accessed, allowing it to check for updates on the server. - Fixed an issue where external folders were not refreshed after closing and reopening Textastic. Other improvements: - Removed unnecessary animations when reordering tabs via drag and drop. - Fixed an incorrect scroll indicator position when switching tabs after showing or hiding the keyboard. - Improved behavior when the app moves to the background while the on-screen keyboard is displayed. - Fixed an issue on iPad where the current file wasn't always selected in the file list when switching tabs.

- Fixed an issue where debug log entries were written for (S)FTP connections even when the debug log setting for that connection was not enabled. - Resolved an issue with entering Japanese characters on iOS 18 when using an external keyboard.

- Markdown Preview Customization: You can now add custom HTML to the head section of the generated Markdown preview. Save your HTML in “Local Files/#Textastic/markdown_head.html,” and it will be used for Markdown previews. This can be used to load JavaScript libraries like MathJax or Highlight.js, for example. - Added buttons in Settings -> Web Preview to open “markdown.css” and “markdown_head.html” directly in the editor, making customization simpler. - Improved File Transfer Reliability: Uploads to (S)FTP, Dropbox, and WebDAV are now more consistent, with enhancements to file coordination during uploads. - Enhanced (S)FTP Debugging: Added detailed timestamps and optimized logging in (S)FTP debug logs for better insights during connection troubleshooting. - Library Updates: Updated libssh2 and libcurl to the latest versions for improved performance and compatibility. Fixes and Improvements: - Fixed an issue where the syntax name in file properties wasn’t updated after selecting a new syntax. - Resolved a bug where internal syntax definitions that were supposed to be hidden could be selected if the syntax definition was not yet fully loaded (e.g. "Make Output", "Cargo Build Results", "PHP Source", "Swift Standard Library", etc.). - Fixed a crash that occurred when connecting to certain non-standard SSH servers. - The app no longer prompts users to connect to a Wi-Fi network when starting while Airplane mode is enabled. This behavior was removed by deleting UIRequiresPersistentWiFi from the app’s Info.plist. - Corrected an issue where the file transfer status label wasn’t displayed.

Improved creation of new files: - New files can now be created with just two taps: After tapping the “+” button, a file name is suggested (e.g. “Untitled.md”), which can be accepted directly with the “Create” button. - The file extension can now optionally be selected from a menu. This menu can be customized via Settings -> New File. - The preselected file extension can also be configured in settings. Other improvements: - Custom CSS for Markdown preview: Save your custom styles in the file “Local Files/#Textastic/markdown.css” and the web preview will use it when previewing Markdown files. - Improved (S)FTP upload and download speed over fast network connections by using larger send and receive buffers. - The Wi-Fi IP address for the WebDAV server is now determined in a different way. This should fix a rare problem where the WebDAV server could not be activated even though Wi-Fi was available. - Fixed: custom CSS did not work for external files opened with the “Open…” command or shared via the Files app.

This should fix a rare problem where the WebDAV server could not be activated even though Wi-Fi was available.

- Updated libcurl, libssh2, and OpenSSL to the latest versions. The new version of the libcurl library included in this update fixes an issue when uploading files to FTPS servers using TLS 1.3: if the file was larger than about 18 KB, the upload could result in a "partial upload" error and a 0-byte file on the server. This should no longer occur. - File transfer: Improved activity indicator when refreshing remote file lists. - Improved positioning of the code completion list when entering text at the end of a line. - Added “main” tag added to HTML code completion.

- Added support for dark and tinted app icons on iOS 18 and iPadOS 18. - Added support for iPhone 16 Pro and iPhone 16 Pro Max. - Added a context menu to the symbol list that can be used to copy the text of the symbol to the clipboard. The menu also shows the line number of the symbol and allows you to select the symbol in the editor. - Fixed: Clicking on the editor with a trackpad or mouse on iPadOS 18 moved the insertion point to the beginning of the file if the editor was not previously active. - Other minor improvements.

- The font "System (SF Mono)" can now be selected in the code editor and SSH terminal settings. - You can now add Dropbox folders that are available in the Files app as external folders to Textastic! There has been a recent update to the Dropbox app so that it is now possible to open entire folders and not just individual files with the iOS file picker. - Improved the folder selection to work much better with external folders that need to retrieve information from a server (like Dropbox and Secure ShellFish). - Added two new FTPS settings: you can now set the minimum and maximum TLS version to be used when connecting to FTPS servers. More information below. - The names in the FTP settings have been updated to use the term "TLS" instead of "SSL". - The web preview now supports landscape orientation on all iPhone models. - Fixed: When using an external keyboard on iPhone, the additional keys above the on-screen keyboard now avoid the home indicator area. - Fixed: Bold, italicized text (e.g. in Markdown) was displayed either in bold or italics, but not both at the same time. - Fixed: Some files (including TypeScript files) did not open in the editor in Textastic 10.3. - Other minor improvements. Additional information on why the FTPS settings for the minimum and maximum TLS version were added: Textastic uses libcurl to transfer files to FTPS servers. On some FTPS servers, uploading a file with curl when using TLS 1.3, if the file is larger than about 18 KB, may result in a "partial upload" error and a 0-byte file on the server. To work around this partial file upload issue, you can reduce the maximum TLS version to 1.2. Note: This is only relevant for FTPS connections. SFTP connections are not affected. This issue has also been reported to the curl project and will hopefully be fixed in a future update of the library. In the meantime, you can use this workaround.
