The main improvement in this release is the support for shared corner fillets. Now, when two open ways meet at a junction, the rounding applies across both ways as a single continuous operation. This feature was suggested by Paul Berry — thank you for the idea.

In addition to this new feature, the plugin is now faster due to improved interaction performance during dragging and preview. I also added several internal fixes to improve stability, mainly regarding rendering and session handling.
FilletTools is available in the JOSM plugin repository.

@BCNorwich, if you installed the first version manually, please remove it from the plugins directory.
The new version is now available for installation through the JOSM settings, just like all other plugins.
Thank you for using it!
