Release Notes

v0.14.3

Compare Source

Changed

• Dropped internal random generators in favor of math/rand/v2, which will have the effect of making code fully incompatible with Go 1.21 (go.mod has specified a minimum of 1.22 for some time already though). PR #​690.

Fixed

• 006 migration now tolerates previous existence of a unique_states column in case it was added separately so that the new index could be raised with CONCURRENTLY. PR #​691.
