# Function name changes
|
||
|
|
|
||
|
|
The function [`workspace`](workspace.md) replaces `solution`. The latter still works, but the former is preferred.
|
||
|
|
|
||
|
|
The function [`filter`](filter.md) replaces the `configuration` function for specifying the current configuration. It provides a more powerful interface for selecting which configuration is current, making it easy to specify flags for different actions, files, etc. The `configurations` setting at the workspace level still sets the available configurations.

# Flag changes
|
||
|
|
|
||
|
|
