flox/flox v1.3.13 on GitHub

Notable features and fixes

This release addresses several bugs and adds new improvements, including:

Changes to the format of error messages and output to improve readability
flox containerize can now produce images that can be run in userspace. This is configured in the manifest by setting the containerize.config.user value to a user:group tuple.
Fixed a performance regression when using flox activate with direnv, where direnv may wait for a backgrounded process that checks for available environment upgrades.
Performance improvements, especially on the activation of environments.
A new flox config option installer_channel can be set to "qa", "nightly", or "stable" in order to control the behavior of upgrade checks for the Flox CLI.
Commands now give precedence to activated environments over the default environment, suppressing the environment selector prompt in some cases.
Upgrade notifications are no longer being duplicated within already activated environments.
flox delete now performs its underlying Nix store work asynchronously so it does not cause user delay
Sourcing of profile scripts has been refactored for all active environments, allowing aliases to be used in nested activation.
If RUST_BACKTRACE or RUST_LIB_BACKTRACE are set to 1 the entire backtrace will be sent to stderr. This is for enhanced debugging and bypasses several other filters that logs go through in most scenarios.
