 +  * 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.

-  Dec2018: A new group was defined: ISMmolecules detected in the interstellar medium, but not in circumstellar shells of late-type stars. +[[archive#catalog_search_form|Archive "Catalog Search Form"]] 
-  * 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.+  Nov2021: A new group was defined: Other hydrocarbonsthat 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.
