This release focuses primarily on solidifying existing functionality, significantly improving performance and fixing a number of important bugs. Additionally this release contains exciting new functionality, including several new components. We want to thank the many contributors to this release (a full list is provided at the bottom), particularly @MarcSkovMadsen (the author of awesome-panel.org) and @xavArtley, who has been hard at work at improving VTK support. We also want to thank the remaining contributors including @philippjfr, @ceball, @jbednar, @jlstevens, @Italirz, @mattpap, @Jacob-Barhak, @stefjunod and @kgullikson88. This release required only minimal changes in existing APIs and added a small number of new ones, reflecting the fact that Panel is now relatively stable and is progressing steadily towards a 1.0 release.
