This post is an update to the proposal for officially support SQLite in WordPress. The initial implementation was included in the Performance Lab plugin and then released as a stand-alone plugin.
That initial implementation was based on wp-sqlite-db by @aaemnnosttv, which in turn, was a fork of an older plugin.
Over the course of the last 6 month, issues with that implementation surfaced and the project experienced some limitations. As a result, we (@zieladam and @aristath) decided to rewrite it using a more future-proof concept.
