(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.

2009 {{CIAAW2009}} (introducing interval notation; Ge):

"Atomic weights of the elements 2009 (IUPAC Technical Report)". Pure and Applied Chemistry. 83 (2): 359–396. 12 December 2010. doi:10.1351/PAC-REP-10-09-14.

2011 {{CIAAW2011}} (interval for Br, Mg):

"Atomic weights of the elements 2011 (IUPAC Technical Report)". Pure and Applied Chemistry. 85 (5): 1047–1078. 29 April 2013. doi:10.1351/PAC-REP-13-03-02.

2013 {{CIAAW2013}} (all elements listed):

2015 {{CIAAW2015}} (ytterbium changed):

"Standard Atomic Weight of Ytterbium Revised". Chemistry International. 37 (5–6): 26. October 2015. doi:10.1515/ci-2015-0512. eISSN 0193-6484. ISSN 0193-6484.

2017 {{CIAAW2017}} (14 values changed):

"Standard atomic weights of 14 chemical elements revised". CIAAW. 2018-06-05.

2019 (hafnium value changed): Meija, Juris; et al. (2019-12-09). "Standard atomic weight of hafnium revised". CIAAW. Retrieved 2020-02-25.
2020* (lead value changed): Zhu, Xiang-Kun; Benefield, Jacqueline; Coplen, Tyler B.; Gao, Zhaofu; Holden, Norman E. (1 October 2020). "Variation of lead isotopic composition and atomic weight in terrestrial materials (IUPAC Technical Report)". doi:10.1515/pac-2018-0916.

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

2021 {{CIAAW2021}} (all elements listed); (4 values changed; introduced new symbol; merge "conventional" into "abridged" columns; change uncertainty notation (use "±")

Prohaska, Thomas; Irrgeher, Johanna; Benefield, Jacqueline; Böhlke, John K.; Chesson, Lesley A.; Coplen, Tyler B.; Ding, Tiping; Dunn, Philip J. H.; Gröning, Manfred; Holden, Norman E.; Meijer, Harro A. J. (2022-05-04). "Standard atomic weights of the elements 2021 (IUPAC Technical Report)". Pure and Applied Chemistry. doi:10.1515/pac-2019-0603. ISSN 1365-3075.
Uncertainty handling

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

Possolo, Antonio; van der Veen, Adriaan M.H.; Meija, Juris; et al. (4 Jan 2018). "Interpreting and propagating the uncertainty of the standard atomic weights (IUPAC Technical Report)". doi:10.1515/pac-2016-0402. Retrieved 20 Oct 2020.
{{CIAAW2021}}: changing notation (i.e., interpretation, not the value) from 123.45(2) into 123.45±0.02
