Collabora Online 4.2.0

A perfect combination of functionality and privacy

Cambridge, United Kingdom, March 5, 2020Collabora Productivity, the driving force behind bringing LibreOffice to the cloud, is excited to announce a major new release of the enterprise-ready online suite Collabora Online 4.2.0. This release includes a fresh look, mobile improvements and better interoperability alongside new dialogs and functionality. Collabora Online enables users and enterprises to work on rich documents in the cloud and to collaborate effectively hosting their own services on-premise. Collabora Online is the perfect online document solution for organizations and services that want to choose digital sovereignty, respect for their users privacy and want to stay in control of their own documents and data.



A fresh clean look, feature rich side-bar, and much much more

This major update of Collabora Online comes with a fresh new user interface and is built on top of the stability and performance of our LTS version of LibreOffice: Collabora Office 6.2. This new Collabora Online includes many improvements in functionality and user-friendliness as well as a raft of bug fixes and polish. The most obvious new feature is the powerful sidebar, which allows users to easily change settings for text, tables, colours, charts and other objects in the documents. It gives Collabora Online almost the same feature- richness available in Collabora Office on the desktop. Furthermore there is a redesigned status bar, much-improved toolbars and a powerful function wizard now available in Calc online. Copy and paste of rich text and content is added for online functions, and our responsive user interface adapts attractively to smaller and mobile screen sizes.

Extending our great interoperability

Among the all improvements, there is also much improved interoperability with Microsoft Office files. Smart art, rotated and left-right text in tables, pivot tables, special sections and headers in text files, math and gradients in Powerpoint files and much more.

Rich chart functions from the sidebar

The sidebar now gives you access to a wide range of features for charts. Select the chart and it is easy to choose from chart types such as bars, lines and points, pies and more, and also whether the diagram should be displayed in 3D. The sidebar also provides other elements and details, for example titles and legends, colours, transparency, axes and grids. All you need for rich chart editing, is available in Collabora Online.

Magic in Calc online with a powerful function wizard for your formulae

If you work on formulae, especially more complex formulae with many parameters, the function wizard in Calc is extremely helpful. It makes handling complex formulae as simple as possible by offering access to all elements of the structure and showing detailed explanation for the different arguments. This makes using the full set of hundreds of interoperable formulae easy!

In excellent condition: Calc brings full conditional formatting

Conditional formatting is a very effective way to understand and visualize your data: you can choose what formatting or icons your cells will receive for certain values.
Collabora Online already offered a limited palette of conditional formats in the tool bar, but the new version of Collabora Online now gives you access to the full set of possibilities by displaying the dialogs for the feature. All you need for creating and adapting conditional formatting is now available in Collabora Online.

Smooth zooming in Calc: scaling of spreadsheets improves significantly

The scaling of spreadsheets sees a major improvement in Collabora Online 4.2.0. While previously (as in other products) the choice was 100% or 200%, now you can select a zoom level that best suits you. This improvement is accessible with a comfortable quick selector in the lower right corner.


Proudly presenting the cool and handy Impress sidebar

Collabora Online now brings you lots of new functionality via the new sidebar in Impress. You can adjust character settings, font-types, objects, sizes, colours, spacing and more from the sidebar. In addition changing the slide layout and even choosing and editing Master Slides is also possible. This provides unprecedented functionality for online editing and is very convenient! All you need to use and edit presentations is available in Collabora Online.

A fantastic image: working with pictures is easier and more precise

Images are fun, and working with them across all types of documents has been massively improved in Collabora Online 4.2.0. Rotating is easy with the clear handles and the new sidebar allows you to adjust colours, brightness, contrast and transparency. You can also use the sidebar module to arrange the foreground or background positioning of your images.


Paste how you like: rich copy/paste features between different documents

When doing work online, you frequently have multiple documents open that need to be combined via copy and paste. In the browser, however, rich copy and paste features are far from trivial. Now the great news is that Collabora Online introduces copying and pasting of rich formatted content like images, charts, and other complex elements across different types of document. Almost all you can wish for working in multiple documents, is now available in Collabora Online.

Enhanced online colour picker

Selecting your desired colour for an object is much more convenient in Collabora Online 4.2.0. In addition to the usual colour selector offering a palette, a new colour picker to choose any custom colour is now available. Use it with text and background in presentations, lines in spreadsheets and presentations, text and background for floating frames in text documents.

Improved collaborative editing with clear links in text documents

Launching links in previous versions required a control-click, which was hard to discover. In Collabora Online 4.2.0, when you collaborate on a document and you want to know the destination of a link, then our new release shows it at a glance. If the mouse cursor is over a link, you will see a pop-up displaying the links target. The pop-up also allows you to see and access the destination with a single click.

Redesigned and clear new icons and a attractive theme

The new design of the icons embellishes the upper toolbar. The new theme is tidier, generally clearer and has more generous spacing, with more distinct highlighting of selected buttons. All of this increases productivity and reduces friction.

New buttons and theming make things more attractive and easier to work with

The status bar benefits from our visual redesign too. Not only does it look cleaner, it also improves quick access to more functions. For example, the language in documents can now also be set via a pop-up.

Table editing: faster with the sidebar and in-document handles

In Collabora Online Writer it is now possible to manipulate tables extensively from the sidebar and we have also added easy-to-use in-document selection handles that make adjusting row height and column width very user-friendly. These features are a convenient extension of the table dialogue, that still also offer access to the tiniest details.

You want to insert rows or columns from here? Of course! Or delete some or all of them? A click! Furthermore, the sidebar also allows you to set the background colour, to fine-tune the sizes of rows and columns, as well as merging cells or distributing them evenly. Really all you would wish for if you are working with tables, is available in Collabora Online.

Table of contents

Collabora Online now allows you to configure the full table of contents in text documents, thanks to the new Table of Contents dialog. So even online, you can customize your complex table of contents in a few clicks according to your wishes. For example, you can edit the entries and change style, background or columns. In the same way you can update indices of figures, tables and so forth. This brings the full power of rich table of contents and index creation to Collabora Online.
