Looks like I've missed a release ;) but now 2.3.19 has been upload to pypi so there won't be 2.3.18 don't search for it ;)
Some bugfixes mainly:
- There was an issue with set_default_scope and a null scope
- There was an event issue while retreiving contacts
- I modified the way dtr is handle (by default it's not touched now, because playing with rts/dtr can reset the node or fire the push button ... please open an issue if anything weird happens to your node, it has driven me crazy ;) )
Full Changelog: v2.3.17...v2.3.19
