Bug Fixes ^^^^^^^^^

• Fix getting release by tag in lazy mode ([#3469](https://github.com/pygithub/pygithub/issues/3469) <https://github.com/PyGithub/PyGithub/pull/3469>) (7d1ba281e <https://github.com/PyGithub/PyGithub/commit/7d1ba281e>)

Version 2.9.0 (March 22, 2026)

Notable changes ^^^^^^^^^^^^^^^

Lazy PyGithub objects """""""""""""""""""""

The notion of lazy objects has been added to some PyGithub classes in version 2.6.0. This release now makes all CompletableGithubObject\s optionally lazy (if useful). See [#3403](https://github.com/pygithub/pygithub/issues/3403) <https://github.com/PyGithub/PyGithub/pull/3403>_ for a complete list.

In lazy mode, getting a PyGithub object does not send a request to the GitHub API. Only accessing methods and properties sends the necessary requests to the GitHub API:

.. code-block:: python

# Use lazy mode
g = Github(auth=auth, lazy=True)
these method calls do not send requests to the GitHub API
user = g.get_user("PyGithub")    # get the user
repo = user.get_repo("PyGithub") # get the user's repo
pull = repo.get_pull(3403)       # get a known pull request
issue = pull.as_issue()          # turn the pull request into an issue
these method and property calls send requests to Github API
issue.create_reaction("rocket")  # create a reaction
created = repo.created_at        # get property of lazy object repo
once a lazy object has been fetched, all properties are available (no more requests)
licence = repo.license

All PyGithub classes that implement CompletableGithubObject support lazy mode (if useful). This is only useful for classes that have methods creating, changing, or getting objects.

By default, PyGithub objects are not lazy.

PyGithub objects with a paginated property """"""""""""""""""""""""""""""""""""""""""

The GitHub API has the "feature" of paginated properties.
