Arduino IDE 1.8.10 - Warning....

[skywatch]

The new arduino 1.8.10 has problems. I updated to this and previously compiled sketches will not compile. I reverted to 1.8.9 and all is well again.

There is a lot of posts on arduino about issues with 1.8.10. - I am using the win 10 x64 version.

Still valid in 2020. Got a compilation error "Error resolving FQBN: missing". Downgrade to 1.8.9 helped

1.8.12 is OK, so no more problems for you either I hope.
