The status board for SQLite version 3.12.0 (https://www.sqlite.org/checklists/3120000/index) is now active. The release will occur when all items go green.
The "Pre-Release Snapshot" over at https://www.sqlite.org/download.html contains the latest code. A preview of the change log can be seen at https://www.sqlite.org/draft/releaselog/3_12_0.html If you have any issues or concerns with the current code, you should raise them *very soon*. -- D.
