What's New in Collabora Office

26.04.3

September 8, 2026

Welcome to Collabora Office 26.04! We've been hard at work upgrading Collabora Office Mobile to 26.04, which brings improvements in interoperability and look-and-feel. We've also fixed some mobile-specific bugs, such as black borders which would display around some documents. As always, the source code for our office suite is freely available online, however the location has moved. You can find our source code at https://gerrit.collaboraoffice.com/ Thank you so much for using Collabora, we'll see you next month!

Too buggy to use

I really want to support the app, but so many basic functions either don’t work at all, or bug out like crazy. I can’t undo with command, even though it says I can. I can’t crop pictures, I can’t add backgrounds, and the list is really growing. Do you need testers or something?

Until I Dump Apple For Linux Soon It Will Do.

My 34 year association with Apple will end soon when able to purchase a new laptop and migrate completely to Linux. I can’t nor will continue to allow myself to be increasingly locked into Apple’s high security electric fenced in prison yard for the sake of being a living bank account for the enrichment of their investors anymore. Nor buy the ongoing marketing lyes that it’s for my own security or that today’s version of Apple is ethically the same as it was twenty years ago. It hasn’t been for roughly fifteen years. Besides Linux is a more secure system than OSX.

That said over the past year Apple has quietly made it increasingly difficult to use third party apps. Apple wants to control the choices users make driving them to their weak and seldomly meaningfully updated native applications serving as nothing more than front doors to their subscription services , iCloud services, and online stores. Apple even changes their devices in ways to force their users into this. Consider the artificial changes Apple made to iBooks with their release of Catalina forcing iMac users to increase iCloud subscriptions or make the choice of no longer maintaining their own private libraries on their tiny but expensive internal drives. All the while subtly “re-educating” their loyal customers that it was a far better solution to buy from their online store.

So with the limitations this app must function as and most likely those to come as Apple reverts backwards to the era pre-Steve Jobs return when they ran Apple into the ground in the early nineties, i will deal with this.

Next year I trade this new iPhone in for an android or anything other than an other iPhone. I should have listened to my brother and friends when they made their exodus from Apples prison facility but noooooo. My stupidity.

Three decades and countless Apple products is enough.

Does what I needed - open encrypted .ODS spreadsheet from LibreOffice

No other app on my iPhone wanted to open my encrypted LibreOffice Calc file. Getting silly error messages like ’try again later’. Installed Collabora Office and it found all files it could open on my phone immediately. Entered file’s password and able to view it. Solved my issue. Whether I’d use it on my iOS device for any advanced editing… not so sure.

Loses your work and other unpredictable behaviour.

Continuously loses your work with no obvious way to save other than export whole document to another copy. Frequently pans thousands of rows or columns away for apparently no reason. Impossible to reliably drag cell selection past the cells in the current view.

Limited support for files with macros and buttons

This app allowed me to open and view most of my open office and libre office files. The spreadsheet it choked on contained macros and buttons.

Obviously I don’t know for certain why this file caused an error and aborted the load, but those are the differences between the files that worked, and those that did not. So, please try to find the bug and correct it. I cannot be the only one who uses these features of Libre Office.
