New in Next Release

This page summarizes all major changes and improvements to Cloudy that will be included in the next release. You may also view the HotFixes and KnownProblems pages, or return to the main RevisionHistory page.

New commands or options

The built-in abundance sets have been exported to external files located in the cloudy/data/abundances directory. These are much easier to add or change since updates no longer require editing the C++ source. There is no change in the abundances type commands which use these files.

The default composition, which will be used if nothing else is specified, is specified by the file cloudy/data/abundances/default.abn. The default composition can be updated by changing this file.

A new abundance "filename" command has been introduced. The chemical composition will be read from filename, which may be located in the current directory or in cloudy/data/abundances.

The abundance "filename" command has a print option to report grain types and abundances used.

Grain physics

Stellar grids and other SEDS

The built-in SEDs have been exported to external files located in the cloudy/data/SED directory. These are much easier to add or change since updates no longer require editing the C++ source. There is no change in the table name commands which use these SEDs files.

A new table SED "filename" command has been introduced. The SED will be read from filename, which may be located in the current directory or in cloudy/data/SED.
