It supports various document formats while maintaining a strong focus on real-time collaboration. Following the major [ONLYOFFICE Docs 9.0](https://itsfoss.com/onlyoffice-docs-9-release/) release that introduced a redesigned interface and AI-powered features, the developers have now rolled out [version 9.1](https://www.onlyoffice.com/blog/2025/10/docs-9-1-released?ref=itsfoss.com). It is the first point release in the 9.x series that focuses on refinement and productivity enhancements. ## 🆕 ONLYOFFICE Docs 9.1: What's New? We begin with the **changes that are common across the various ONLYOFFICE editors**. You can now customize how comments are displayed, filtering between "*Resolved*" and "*Open*" ones in the left panel. Chart editing gets more flexible. The *Explosion* option for 2D pie and doughnut charts is now supported. You can also manage external data sources when copying charts between editors and toggle specific elements like axis titles or error bars. The **Presentation Editor** gets a dedicated toolbar tab for all Slide Master settings, making it easier to access layout options. Over in the **Document Editor**, section breaks now work within block *Content Controls* at any nesting level. Similarly, the **Spreadsheet Editor** sees some serious performance gains in this release. *LOOKUP*, *VLOOKUP*, *HLOOKUP*, and *XLOOKUP* formulas are now faster, with better memory usage and improved handling of mixed data types. ![this shows onlyoffice spreadsheet editor with the new tab design tab on the top of the interface, above the open document](https://itsfoss.com/content/images/2025/10/onlyoffice-spreadsheet-editor-table-design-tab.png) Table management is more streamlined. Formatted table settings have moved to a dedicated "*Table Design*" tab that appears when you're working within a table. Pivot Tables now support date filters, which can be useful for analyzing time-based data. Working with sheets gets quicker too. You can rename them instantly by double-clicking their name, and when entering formulas, active arguments are highlighted, making it easier to track what you're calculating. The **PDF Editor** introduces [a Redact tool](https://itsfoss.com/obfuscate/) for permanently removing sensitive information. Open your file in editing mode, switch to the "*Redact*" tab, and use the "*Mark for Redaction*" button to highlight text. ![the new redact tool for onlyoffice pdf editor is demoed here, the new redact tab is shown above with a piece of text from a document selected for redaction below](https://itsfoss.com/content/images/2025/10/onlyoffice-pdf-editor-redact-tool.png) For larger documents, the *Find & Redact* option helps you quickly locate and select specific words or phrases. You can redact entire pages or page ranges too. Moreover, there are many new annotation tools that expand the markup options. You can select shapes like *Rectangle*, *Circle*, *Arrow*, or *Connected Lines* and draw directly on documents. ### Other Notable Changes Localization gets better with **formula translations for Serbian Latin, Serbian Cyrillic, and Traditional Chinese**. This makes working in native languages more comfortable for users in those regions. The server version introduces an **Admin Panel**. This dashboard lets administrators view server status and configuration settings, and the format support has been extended. And finally, the editors now support *HEIF* images and *HWPML* documents for opening and viewing. Direct conversions from *PDF* to *TXT* and *PPTX* to *TXT* are also possible, and you can insert mathematical formulas in the *MathML* format. ## 📥 Download ONLYOFFICE Docs 9.1 If you're self-hosting, you can grab the latest packages from the [official download page](https://www.onlyoffice.com/download-docs.aspx?ref=news.itsfoss.com).
