dbtenv 2.0.0

Added

• dbtenv now operates at the adapter-version level, introduced by dbt in version 1.0.0. dbtenv can automatically detect the needed adapter version from profiles.yml, or the --adapter argument set in a dbt command passed to dbtenv --execute.
• The execute command's --dbt argument can now take either a dbt version (e.g. 1.0.0) or full pip specifier to use (e.g. dbt-snowflake==1.0.0). dbtenv will attempt to automatically detect the required adapter or version from the environment if not specified.
• dbtenv's version command and config files can now use a dbt version (e.g. 1.0.0) or full pip specifier to use (e.g. dbt-snowflake==1.0.0). dbtenv will attempt to automatically detect the required adapter or version from the environment if not specified.

Changed

• Dropped support for Homebrew.
• Previously created environments through dbtenv 1.0.0 will be ignored.
• dbtenv's default behaviour is now to install missing dbt adapter versions automatically. It can be disabled by setting the DBTENV_AUTO_INSTALL environment variable to false.
• Attempting to install a version of dbt which doesn't exist will exit cleanly, and provide a list of available versions for that adapter.
• Failed dbt version installations exit cleanly, removing the created virtual environment.

Fixed

• Only entries in the environment directory which are dbtenv 2.0.0 environments will be read as installed dbt versions, fixing an issue where dbtenv 1.0.0 environments caused a failure.
• Fixed version command, and all dbtenv config files. These can now take either a dbt version (e.g. 1.0.0) or full pip specifier to use (e.g. dbt-snowflake==1.0.0). dbtenv will attempt to automatically detect the required adapter or version from the environment if not specified.
