Instructions to release a new Spyder-env-manager version

To release a new version of spyder-env-manager (on PyPI and Conda-forge) follow these steps

In order to do a release, you need to have:

An environment with the packages required to do the release (loghub, pip, setuptools, twine, wheel). If using conda, you can create a release environment with
```
conda create -n release python=3.9
conda activate release
pip install -U pip setuptools twine wheel loghub
```
A clone of this repository (usually your fork with an upstream remote pointing to the project original repo)
The corresponding credentials (PyPI, GitHub, etc).

Update local repo with

git fetch upstream && git checkout main && git merge upstream/main

Update CHANGELOG.md with

loghub spyder-ide/spyder-env-manager -m vX.Y.Z

Update __version__ in spyder_env_manager/__init__.py (set release version, remove dev0):
```
git add . && git commit -m "Release X.Y.Z"
```

Update the most important release packages with

pip install -U pip setuptools twine wheel loghub

Create source distribution and wheel with
```
python -bb -X dev -W error -m build
```
Check generated files with
```
twine check --strict dist/*
```
Upload generated files with
```
twine upload dist/*
```
Create release tag with
```
git tag -a vX.Y.Z -m "Release X.Y.Z"
```
Update __version__ in spyder_env_manager/__init__.py (add dev0 and increment minor)

Create Back to work commit with

git add . && git commit -m "Back to work"

Push changes and tag with

git push upstream main && git push upstream --tags

Create a GitHub Release (Draft a new release and Publish release). You can use the Auto generate release notes as a base template for the release description and to that add a link to the Changelog (the new release related info).

After doing the release on PyPI check for the regro-cf-autotick-bot automatic PR on the Spyder-env-manager feedstock repo. Review it, check if any dependency or changes are needed and merge it.
