The current version of SQLite (in Python 3.6) is 3.7.17 which was released almost 5 years ago - https://www.sqlite.org/releaselog/3_7_17.html

Given that user updating of the version of SQLite used by Python is something of a pain (and the process is different across platforms (*and* different again for virtual-envs across platforms)), can the built-in version please be updated to a more recent version? This will allow usage of new SQLite features and users can benefit from a lot of performance enhancements/optimisations too.

SQLite has excellent backwards compatibility, so except for any regressions (and they run over a hundred million tests per release to keep them to a minimum), any newer version will be backwards compatible with that version.
Thanks
