The reno command line tool is used to create a new release note file in the correct format and with a unique name. The new subcommand combines a random suffix with a “slug” value to make the new file with a unique name that is easy to identify again later.
$ reno new slug-goes-here
Created new notes file in releasenotes/notes/slug-goes-here-95915aaedd3c48d8.yaml
Within OpenStack projects, reno is often run via tox instead of being installed globally. For example
$ tox -e venv -- reno new slug-goes-here
venv develop-inst-nodeps: /mnt/projects/release-notes-generation/reno
venv runtests: commands[0] | reno new slug-goes-here
Created new notes file in releasenotes/notes/slug-goes-here-95915aaedd3c48d8.yaml
venv: commands succeeded
congratulations :)
$ git status
Untracked files:
(use "git add <file>..." to include in what will be committed)
releasenotes/notes/slug-goes-here-95915aaedd3c48d8.yaml
By default the new note is created under ./releasenotes/notes. Use the --rel-notes-dir to change the parent directory (the notes subdirectory is always appended).
The note file is a YAML file with several sections. All of the text is interpreted as having reStructuredText formatting.
prelude
General comments about the release. The prelude from all notes in a section are combined, in note order, to produce a single prelude introducing that release.
features
A list of new major features in the release.
issues
A list of known issues in the release. For example, if a new driver is experimental or known to not work in some cases, it should be mentioned here.
upgrade
A list of upgrade notes in the release. For example, if a database schema alteration is needed.
deprecations
A list of features, APIs, configuration options to be deprecated in the release. Deprecations should not be used for something that is removed in the release, use upgrade section instead. Deprecation should allow time for users to make necessary changes for the removal to happen in a future release.
critical
A list of fixed critical bugs.
security
A list of fixed security issues.
fixes
A list of other fixed bugs.
other
Other notes that are important but do not fall into any of the given categories.
Any sections that would be blank should be left out of the note file entirely.

Release notes may include embedded reStructuredText, including simple inline markup like emphasis and pre-formatted text as well as complex body structures such as nested lists and tables. To use these formatting features, the note must be escaped from the YAML parser.
The default template sets up the prelude section to use > so that line breaks in the text are removed. This escaping mechanism is not needed for the bullet items in the other sections of the template.
To escape the text of any section and retain the newlines, prefix the value with |. For example:
---
prelude: |
This paragraph will
retain its newlines
when the value is passed to the
reStructuredText parser, which
will then merge them into
a single paragraph without
breaks.
| These
| lines
| are prefixed
| with | so the reStructuredText
| parser will retain
| the line breaks.
other:
- |
This bullet item includes a paragraph and a nested list.
* list item 1
* list item 2
::
This example is also rendered
correctly on multiple lines
as a pre-formatted block.
See Examples for the rendered version of the note.
Run reno report <path-to-git-repository> to generate a report containing the release notes. The --branch argument can be used to generate a report for a specific branch (the default is the branch that is checked out). To limit the report to a subset of the available versions on the branch, use the --version option (it can be repeated).
Notes are output in the order they are found by git log looking over the history of the branch. This is deterministic, but not necessarily predictable or mutable.
