Updates
(This list: )
CIAAW may publish changes to atomic weights (including its precision and derived values). Since 1947, any update this is done in odd years nominally; the actual date of publication may be some time later.

- * "2020" is an inconsistent year for change publication: CIAAW maintains that only odd years, changes are publicised.

- Uncertainty handling
About notation and handling of the uncertainty in the values, including those in [ ] range values:

- {{CIAAW2021}}: changing notation (i.e., interpretation, not the value) from 123.45(2) into 123.45±0.02
