dist/orig contains the stock sqlite3 code, as packaged in the ZIP file above.

dist contains a copy of dist/orig, but with the Android.patch file applied.
Please see Android.patch for a list of differences between stock and
Android.

The Android specific patch applied cleanly and was regenerated.

This is a regular maintenance release which contains performance
improvements to the query planner and some non-critical bug fixes.

More details about the release are available here: https://sqlite.org/releaselog/3_19_0.html
