The CDS conda environments aim to support all ligo software and much third party software needed on LIGO cds workstations.
The CDS conda environments are modified versions of the [IGWN conda environments](https://computing.docs.ligo.org/conda/), but the environments are not always synchronized. CDS updates its environments weekly or more often, but may hold back package updates that IGWN has adopted.
## Publishing of CDS environments
These environments are published as conda environment definition files.
The environment definition can be found on the [LHO repository server](https://apt.ligo-wa.caltech.edu/sources/conda/environments/)
### The default environment
The latest CDS environment definition can always be found here: []():
Earlier versions can be found here: [](), named after the date of release. See below for a description of the package changes from version to version.
