--- layout: post title: diffoscope 63 released author: Ximin Luo --- The diffoscope maintainers are pleased to announce the release of diffoscope version `63`. This version includes the following changes: ``` * Add myself to Uploaders. * Greatly improve speed for large archives by fixing O(n^2) complexity for archive member lookup. - There is still O(n^2) complexity for archive member extraction, but this is less noticeable for various reasons and would require more complexity to fix, so for now is left as a task for the future. * Text output: add coloured diff support via colordiff(1). * Html-dir output: add +/- buttons to fold sub-diffs (i.e. toggle their visibility) as well as the whole diff itself. As with similar features in other programs, the effect affects all descendants if you shift-click. ``` You find out more by [visiting the project homepage](https://diffoscope.org).
