This is the third update of Collabora Office 22.05 with bugfixes. Interoperability fixes Security upgrades of 3rd party libraries (curl, expat, libpng, nss, python)

This is the second update of Collabora Office 22.05 with bug fixes and new features. Fixes and Improvements: • Content controls in Writer In previous release support of content controls were introduced. In this release there is a new type of content controls is supported: the combo box. Now it is also possible to export forms to PDF, and content controls will be mapped to PDF form widgets. Therefore the resulting PDF form will be fillable, too. Writer now supports titles and tags for content controls, which helps providing context for the filled in text even if the placeholder text is replaced already. • Calc performance improvements (e.g. speed up large sheet with lots of conditions) • PPTX interoperability improvements • Fix SVG export of tabulators in slideshows • Better support for importing TIFF files. The internal legacy TIFF importer was replaced to the libtiff-based importer. This feature was backported from LibreOffice 7.4 • All fixes from the latest LibreOffice 7.3.7 release

This is the first update of Collabora Office 22.05 with bugfixes and new features. Fixes and Improvements • Chart data table is a feature of charts, that presents in the chart area a data table with the values that are visualised by the chart. The data table is positioned automatically at the bottom of the chart, and can for certain chart types replace the X-axis labels. Read more in Tomaž Vajngerl's blog: https://tomazvajngerl.blogspot.com/2022/09/chart-data-tables.html • In Impress, color themes are supported now for shape fill color, in addition to the previously implemented theme support of shape text color. Read more in Miklos Vajna's blog: https://vmiklos.hu/blog/sd-theme-shape-fill.html • Writer now supports content controls: a new way to set properties on a piece of text, primarily for form filling purposes. This feature improves compatibility with the DOCX format. Plain text, rich text, checkbox, dropdown list, picture, and date picker are supported. For the interested reader more details can be found in Miklos Vajna's blog: https://vmiklos.hu/blog/sw-content-controls.html, https://vmiklos.hu/blog/sw-content-controls2.html, https://vmiklos.hu/blog/sw-content-controls3.html • All fixes from LibreOffice 7.3.6 • Add Persian spelling dictionary

Calc in Collabora Office now supports up to 16384 columns in spreadsheets. This is a sixteenfold increase in the maximum number of columns compared to previous versions. Combined with up to one million rows per spreadsheet, Calc can now handle enormous amounts of data on the right hardware. Previous performance improvements in Calc paved the way for this feature which also increases the interoperability with Excel spreadsheets from Microsoft. Sparklines are mini-charts found in Microsoft’s XLSX format. The support for them premieres with the release of Collabora Office 22.05. We have been looking at Writer and how it can better render Word-style borders around pages, tables and paragraphs. Word users expect to be able to import their documents to Writer and have a rendering that is true to the original. A series of fixes to the way page, table, and paragraph borders of OOXML documents are imported into and painted in Writer meets this desire. This is done conditionally, so existing ODF documents are left unchanged. As a result of this work, Writer now has a set of improvements to better render Word-style borders around pages, tables and paragraphs. This version introduces the ability to add hyperlinks to shapes in Writer. This option was previously only available in spreadsheets and presentations, but not in text documents. At the same time, links in shapes were previously also lost when importing Word documents, so this feature also improves interoperability Writer has now the ability to handle linked character styles and paragraph styles from Word documents. This improves interoperability and may improve the style previews and the UI of future releases. Earlier, links were lost on round-trips between Writer and Word which led to unwanted displays inside the style pickers. Impress now correctly renders shadows for table shapes, even if the shadow itself or the fill of the table cells have transparency. This is another enhancement of the compatibility with Microsoft’s PowerPoint with regard to the support of transparency in table cell fills and table shadows. A few new PowerPoint-compatible screen sizes have been added to the Paper Format options inside the Slide Properties. The “Widescreen” option is currently used in PowerPoint, while the different “On-screen Show” options are used in previous versions of PowerPoint and Google Slides. Any exported file created with these sizes will be treated as a preset size (as opposed to a user size). The same applies on import. In addition to improving interoperability, one of the main areas of activity for Collabora engineers is the continued improvement of performance. In the new main version of Collabora Office, significant performance improvements can be found in all modules, which were achieved by streamlining the code.
