thanks, looks good, i need to make some wheels and publish them when i merge this. will try to have a look soon

[wbolster]

thanks, news file was incomplete. used yours as a base and turned it into 1.1.0. which is now on pypi

jfyi: as usual this took more effort than expected. there's a newer leveldb release since the previous plyvel release. this new version should be used in the linux wheels. but the dockerfile was failing after bumping the version. the download url changed. easy enough. but the build system changed as well, which needed some new configuration for the build to succeed.

Thanks for the feedback, I'll keep that in mind for future contributions 👍

maintaining 30+ smallish oss projects requires many "simple" tasks but the context switching plus the many complications doing those (because computers hate me) basically mean that nothing is "just x" or "simply y".

"chores" contributions such as this pr actually help a lot. thanks! 😎
