"""Generate draft and release notes in Markdown from Github PRs. |

|
|
||||||
|
You'll need a github API token to avoid being rate-limited. See |
||||||
|
https://help.github.com/articles/creating-a-personal-access-token-for-the-command-line/ |
||||||
|
|
||||||
|
This script collects PRs using "git log X..Y" from local repo where X and Y are |
||||||
|
tags or release branch names of previous and current releases respectively. |
||||||
|
Typically, notes are generated before the release branch is labelled so Y is |
||||||
|
almost always the name of the release branch. X is the previous release branch |
||||||
|
if this is not a patch release. Otherwise, it is the previous release tag. |
||||||
|
For example, for release v1.17.0, X will be origin/v1.16.x and for release v1.17.3, |
||||||
|
X will be v1.17.2. In both cases Y will be origin/v1.17.x. |
