@SabotageAndi or @tzongithub what's the plan forward with this and the other PRs? What needs to be done to move forward?

[bollhals]

@SabotageAndi or @tzongithub There are still a whole lot of PR's open for the Bodi, They should be fairly simple to review and it would improve the performance for it. Can we align on how to proceed with it? It's been years already since I filed them :)

[SabotageAndi]

@bollhals Sorry that we never got to these PRs.
I left Tricentis last month, so I no longer work on SpecFlow.

[bollhals]

All the best for your new opportunities! Any Idea who would be best to ping to finish this?

[SabotageAndi]

@gasparnagy should still work for Tricentis as a freelancer.

@gasparnagy should still work for Tricentis as a freelancer.

That is unfortunately not true. They haven't renewed my contract (yet?). So @bollhals I suggest contacting them at [email protected].
