Minor wordsmithing in CHANGELOG.md
### Major Changes
-- When running a python program, pulumi will now run `python3` instead of `python`, since `python` often points at Python 2.7 binary, and Pulumi requires Python 3.6 or later. The environment variable `PULUMI_PYTHON_CMD` can be used to provide a different binary to run.

### Improvements
- Fix an issue where `pulumi` would not respect common `NO_PROXY` settings (fixes [pulumi/pulumi#2134](https://github.com/pulumi/pulumi/issues/2134))
-- The CLI wil now correctly report any output from a python program which writes to sys.stderr (fixes [pulumi/pulumi#1542](https://github.com/pulumi/pulumi/issues/1542))

- Don't install packages by default for Python projects when creating a new project from a template using `pulumi new`. Previously, `pulumi` would install these packages using `pip install` and they would be installed globally when `pulumi` was run outside a virtualenv.
- Fix an issue where `pulumi` could panic during a peview when using a first class provider which was constructed using an output property of another resource (fixes [pulumi/pulumi#2223](https://github.com/pulumi/pulumi/issues/2223))
-- Fix an issure where `pulumi` would fail to load resource plugins for newer dev builds.
+- Fix an issue where `pulumi` would fail to load resource plugins for newer dev builds.
- Fix an issue where running two copies of `pulumi plugin install` in parallel for the same plugin version could cause one to fail with an error about renaming a directory.
