+ `-verbose` flag added with multiple levels, replacing `-disable_output` (which is now the default behavior) + New command `puts_verbose` added, to be used for extra pieces of information + ./flow.tcl header now includes version, copyright and licensing information + Added `-last_run` flag allowing you to quickly resume the last run (useful with -interactive) + Added `open_in_klayout` command that lets you open the CURRENT_DEF in Klayout ~ `env.py issue-survey` now detects whether it's running inside the container and warns accordingly ~ RUN_KLAYOUT, RUN_KLAYOUT_DRC, RUN_MAGIC_DRC, RUN_LVS now only control noninteractive flows ~ Full git hash added to containers ~ Various Documentation Updates ~ Changed verbosity of various output messages - Removed `-disable_output` (now the default behavior) - Removed OpenLane ASCII art - Removed various "chatty" messages, including things succeeding (shut up unless something fails)
