changelog/v0.16.9.md
Update the error message when When pulumi commands fail to detect your project to mention that pulumi new can be used to create a new project (fixes pulumi/pulumi#2234)
Added a --stack argument (short form -s) to pulumi stack, pulumi stack init, pulumi state delete and pulumi state unprotect to allow operating on a different stack than the currently selected stack. This brings these commands in line with the other commands that operate on stacks and already provided a --stack option (fixes pulumi/pulumi#1648)
Added Output.all and Output.from_input to the Python SDK.
During previews and updates, read operations (i.e. calls to .get methods) are no longer shown in the output unless they cause any changes.
Fix a performance regression where pulumi preview and pulumi up would hang for a few moments at the end of a preview or update, in addition to the overall operation being slower.
