**Task Indicator | Custom CSS Improvements | Bug fixes and performance improvements** This update primarily brings two new features to the table: A visual task indicator for long-running tasks, and great improvements in the experience for Custom CSS users. First, our new **long-running task indicator** gives you a better overview and insight into any task that you perform in Zettlr that can take long, such as exporting projects to PDF. Now, whenever you start a task that might take a while, Zettlr will show an indicator in the toolbar. It encodes several pieces of information, such as how many tasks are running, how many have failed, and how many were successful. Click the indicator to see more details for each task, including an explicit run time. Once you "clear" the tasks, the icon will disappear again until you start new tasks. If you have hardware acceleration disabled, Zettlr will only show an icon, but if you keep it enabled, you will see an animation. Second, we have cleaned up the editor CSS. More specifically, the editor themes now make use of CSS variables to style most of their content. This can greatly reduce the complexity for those of you who want to use cus

v4.4.0

**Security Fixes | File Manager Improvements | Bug Fixes** This update improves primarily on two fronts: the file manager and how you can navigate your files, and the security model of the app. First, this update brings improvements in the file manager, making it easier for you to navigate all your files and folders. This includes a few bug fixes that improve the behavior of the file manager. For example, opening up folders of containing files now works more reliably, and the file manager once again scrolls any newly activated file into view. Second, we have heavily increased the safety when using the app. We now disallow more potentially dangerous code from executing and have overhauled the security model of the app to better reflect how users interact with the app. As always, you can view the full changelog below. > **Do you enjoy Zettlr?

v4.3.1

Mar 30, 2026
**Bug Fixes and Performance Updates** For this small update, we've fetched the polishing cloth and improved things here and there, but nothing big has happened. The one notable fix is that Zettlr now properly escapes path names passed to shell commands during exports. In very specific circumstances, it was possible to make Zettlr execute unexpected commands during exports. This update improves this behavior so that it is no longer possible. > **Do you enjoy Zettlr? With the recent spikes in SSD and RAM costs, our server costs have skyrocketed.

v4.3.0

Mar 21, 2026
**New File Manager Controls | QoL Updates | Bug Fixes | Security Fixes** This release brings many great new things to Zettlr. Besides the obvious batch of bug fixes, this update focuses on improved citation quality, and findability of your files in the file manager. Specifically, this update improves the file manager by allowing you to sort your workspaces and add colors to your folders. You can also close all standalone files or workspaces with a few clicks, if you so wish. In terms of citation support, Zettlr now shows a tooltip after some delay if you hover over a citation with your mouse, showing you the generated bibliography for those items to make sure you actually cite the correct work. Besides that, you now get CSS autocompletion in the Custom CSS editor. The boot sequence of Zettlr is now much more resilient towards missing files, folders, or weird permission errors, so you should have a much better experience in volatile contexts. We also fixed a few potential security issues where unsanitized HTML was rendered in the main window that could possibly be abused by malicious actors. To see what exactly has changed in detail, please review the changelog below. >

v4.2.1

Mar 7, 2026
**Bug Fixes | Updated Dependencies** This update only brings minor things to the table. Most notably, this update fixes the logic of Zettlr to handle extensions to Pandoc readers and writers. Previously, extensions were always removed from readers and writers whenever you imported or exported a file. Now, if you specify an extension, this will work again. This means, previously, if you specified a writer in your defaults files disabling the “smart” extension (e.g., `writer: docx-smart`), Zettlr would strip the extension away. Now, these extensions are retained correctly on each import or export. In addition, this update fixes a few oddities after the Zotero 8 update, and updates all dependencies to the newest available versions. # Changelog ## Fixed Pandoc Extension Parsing If you ever used [Pandoc extensions](https://pandoc.org/MANUAL.html#extensions) with Zettlr, you may have wondered why they sometimes appeared not to work. After a report by a user, we have found out that Zettlr never actually parsed these correctly. We decided to make this a bit more visible in the changelog since your exports may have been broken without you realizing. This way you can veri

v4.2.0

Feb 21, 2026
**Preview Mode Updates | Bug Fixes | Quality of Life Improvements** This update brings three distinct sets of improvements. First, it contains a series of new features for the preview mode, which make blockquotes now render with a vertical bar instead of italicized font. In addition, Pandoc divs and spans are now pre-rendered and apply any custom styling you have applied, if applicable. Second, it contains a bunch of minor bug fixes and improvements of some annoying behavior so that the app works better for everyone. This also includes some big improvements of the Brazilian, Japanese, and German translations. Last but not least, this update includes a fix for a bug that had been introduced by the recent Zotero 8 update. Some users were reporting that, after that update, Zettlr would stop suggesting citations, and that other parts of the citation pipeline would randomly fail. This update provides a fix to ensure that your citations should mostly work, even if the output from Zotero contains some minor problems. > **Do you enjoy Zettlr?

v4.1.0

Jan 13, 2026
**Bug Fixes | Performance Improvements** This is the first minor update for Zettlr 4.0. It comes with many fixes and small improvements, but also two new features and a change that you should know about. The two features are that you can now additionally collapse YAML frontmatters and Pandoc divs with the collapse-arrows left of the editor area, and Zettlr furthermore remembers which sections you have collapsed on a per-editor basis. The change pertains to a configuration update that will make downgrading from this version difficult, and which requires your attention. Read everything in the Changelog below. # Changelog ## Read Before Updating In this version, we perform a long-planned configuration change that affects your loaded workspaces and files. Before installing this update, please take note of which workspaces and files you have open, in case they are being closed through this update. (No data will be actually deleted, but this helps you avoid having to search for the folders.) In addition, it is crucial to remember that once you update to this version, **there is no turning back**. If you decide to downgrade to a previous version, your files and wor
