Note: If you're using the desktop version of CAMEO Chemicals 2.1 or later, you can use the automatic update feature to get the latest version. The next time* you start your desktop CAMEO Chemicals, it will notice that there is a new version available and give you the chance to auto update. If you say yes, the program will download and install the new version for you automatically.

What's changed in CAMEO Chemicals 2.4?
Updated data from several sources: AEGLs, DOT Hazard Labels, DuPont, EPA List of Lists, NFPA, and the Hazardous Materials Table (49 CFR 172.101).
Updated reactivity data to match the Chemical Reactivity Worksheet (CRW) v. 3.0 release:
Increased reactive groups from 47 to 64, which also involved updating the reactive group assignments on all chemical records.
Added three new reactivity alert types: pyrophoric, known catalytic activity, and decomposes at elevated temperatures.
Updated other reactivity data fields: Air & Water Reactions and Reactivity Profile.
Added a new field on Potentially Incompatible Absorbents to the Hazards section of the chemical datasheets. Note that these incompatibilities are based on reactive group assignments.
Revised the Compatibility Chart and reactivity predictions to match the CRW release:
Updated pair-wise reactivity predictions, based on new reactive groups.
Revised hazard statements.
Added new Incompatible (red), Caution (yellow), and Compatible (green) headings and color-coded icons to chart.
Made minor changes and bug fixes.
