## March 1st, 2014 release

Weeds used to rely on a Python library, `linedb`, for querying spectral line databases. This library has been developed as part of Weeds, but it has been realized that it could be useful in other GILDAS programs as well. Therefore it has been moved to the GILDAS kernel, after some important modifications to make it more generic and versatile. It is now a separate language (see `help linedb\` for more information). As a consequence, a couple of Weeds commands have been modified:

- The `dbselect` has been removed. The database selection is now made with the `use in` command, which is part of the `linedb\` language.
- The `dbcache` command has also been removed. Users can now build a local copy of a database with a combination of `use in`, `use out`, `select` and `insert`. See section 3 for an example of this.

In addition, the following changes have been implemented in this release:

- `modsource` now allows to model sources with one or several foreground absorbing layers. This is set with the `/absorption` option in the model file. See the `modsource` command help for more information.
- A bug in the interpolation of partition functions as a function of the temperature in `modsource` has been corrected. The interpolation is now done in log-log.
- `lid` now prints the uncertainty on the line frequencies
