| | * Nov. 2023: The information on the meaning of lower case characters as quantum numbers was misleading and has been rephrased. The term //g//<sub>I</sub> was missing in several "useful equations" because it was assumed to be 1 initially. |
| * Mar. 2019: The program of the VAMDC-CDMS was updated. The Classic or ascii-CDMS was moved to this server. Links have been corrected and should work, but a detailed check is pending. The coding of special characters has been adjusted. | * Mar. 2019: The program of the VAMDC-CDMS was updated. The Classic or ascii-CDMS was moved to this server.

| * Dec. 2018: A new group was defined: ISM, molecules detected in the interstellar medium, but not in circumstellar shells of late-type stars. | * Nov. 2021: A new group was defined: Other hydrocarbons, that are hydrocarbons different from the carbon chain species C<sub>n</sub>H and C<sub>n</sub>H<sub>2</sub>, but including isotopologs. |
| * Nov. 2018: A bug in the calculation of A values was fixed. This affected transitions with //g//<sub>up</sub> larger than 999. | |
| * Dec. 2015: new molecule group: cyclic species. | |

| * Dec. 2020: updated AlO, TiO, and acetic acid entries. | * Apr. 2024: added thioxyhydroxymethylium and thionylimide with documentations; updated HCCNC, HNC<sub>3</sub>, and HNCS documentations. |
| * Nov. 2020: updated HCCNC, HNC<sub>3</sub>, and urea entries. | * Mar. 2024: added extragalactic protonated acetylene with documentation; updated H<sub>2</sub>O documentation. |
| * Oct. 2020: added HC<sub>4</sub>NC, 3-butynenitrile, ethynyloxomethylium, and butadiynyliminomethylium with documentations; updated acetamide documentation; modified iminomethylium entry. | * Feb. 2024: added HCNS with documentation. Updated HNCS, HSCN, HNCO, and HCNO documentations. |
| * Sep. 2020: updated C<sub>3</sub>N<sup>−</sup> and C<sub>5</sub>N<sup>−</sup> documentations, and modified that of C<sub>5</sub>S. | * Jan. 2024: updated SiC<sub>2</sub> documentation. The 2-butenenitrile species are counted as two because mutual conversion requires breaking of a (double) bond, hence, the E- and Z-species are different isomers, not conformers. |
