0.20.0 Migration Guide

Removals

Command removals

The following commands were previously deprecated and were removed in this release.

apps: Use apps:list instead.
certs: Use certs:report instead.
certs:info: Use certs:report instead.
checks: Use checks:report instead.
docker-options: Use docker-options:report instead.
domains: Use domains:report instead.
plugin: Use plugin:list instead.
proxy: Use proxy:report instead.
trace: Use trace:on or trace:off instead.
ps: Use enter with a container ID instead to run ps auxww within a container.

The refactor of the proxy plugin removes the following functions from being sourced in plugins:

proxy#get_app_proxy_port_map()
proxy#list_app_proxy_ports()
proxy#filter_app_proxy_ports()
proxy#add_proxy_ports()
proxy#remove_proxy_ports()
proxy#set_proxy_ports()

The informal policy is to allow removal of functions within a functions file if they are not used in OSS plugins. Should you be affected by any such removals, please file an issue to expose the functionality via a plugin trigger.
