Version 2.1 Release Notes
*************************

Version 2.1 has a whole host of new data sources, features, and compatibility
fixes.

Title Command
=============

Liquid Prompt can now display the currently running command as part of the
terminal title. See :attr:`LP_ENABLE_TITLE_COMMAND` for more information.

Development Environments
========================

Multiple new development environments are now detected and displayed, including
AWS profiles, container environment, ``kubectl`` context, Node.js, Ruby, and
Terraform workspace.

Some of these sections are disabled by default, so see their respective config
options for more details and how to enable them:

- :attr:`LP_ENABLE_AWS_PROFILE`
- :attr:`LP_ENABLE_CONTAINER`
- :attr:`LP_ENABLE_KUBECONTEXT`
- :attr:`LP_ENABLE_NODE_VENV`
- :attr:`LP_ENABLE_RUBY_VENV`
- :attr:`LP_ENABLE_TERRAFORM`

Linux sysfs interface
=====================

Both battery and temperature information now support reading from the sysfs
interface on Linux. This means ``sensors`` and ``acpi`` are no longer required
to get battery and temperature information, and the data source is much faster.

Wireless Signal Strength
========================

A new feature exists to track wireless signal strength, and display the value if
it falls below a threshold, similar to the battery feature. See
:attr:`LP_ENABLE_WIFI_STRENGTH` for more information.

Shell Nesting Level
===================

A new feature to display the number of nested shells. See
:attr:`LP_ENABLE_SHLVL` for more information.

ShellCheck
==========

The whole project is now checked with `ShellCheck`_, which has already caught a
few issues, and will help prevent regressions.

Bash-preexec Compatibility
==========================

Liquid Prompt now supports running along side `bash-preexec`_. Simply load
Liquid Prompt `after` bash-preexec.
