+### Major fix: Corruption of Postgres NUMERIC values
+
+⚠️ This release fixes a bug causing corruption of NUMERIC fields when read from Postgres databases. [#863](https://github.com/koordinates/kart/issues/863)
+
+If your repositories use the NUMERIC or NUMERIC(a,b) types and were imported/committed from a Postgres source or working copy, you may have lost data.
+
+Specifically, any numeric values with a scale of zero (no digits after the decimal point) were affected. If the only numerics in your repositories were defined with a scale greater than zero, no data corruption should have occured.
+
+For example, a value of 100 in a postgres database with the type NUMERIC(10, 0) or NUMERIC would have been imported as 1 - losing its trailing zeroes.
+
+However, a value of 100.0 in a field declared as NUMERIC(10, 1) would not have been affected.
+
+Other data types (integer, floating-point etc) are not affected, and repos sourced from other SQL databases (Geopackage, MSSQL, MySQL) were not affected.
