Write a changelog entry if there is a user-visible change. This includes:
We generally don't include changelog entries for:
Until Mbed TLS 2.24.0, we required changelog entries in more cases. Looking at older changelog entries is good practice for how to write a changelog entry, but not for deciding whether to write one.
A changelog entry file must have the extension
*.txt and must have the following format:
Security * Change description. * Another change description. Features * Yet another change description. This is a long change description that spans multiple lines. * Yet again another change description.
The permitted changelog entry categories are as follows:
API changes Default behavior changes Requirement changes New deprecations Removals Features Security Bugfix Changes
Use “Changes” for anything that doesn't fit in the other categories.
Each entry starts with three spaces, an asterisk and a space. Continuation lines start with 5 spaces. Lines wrap at 79 characters.
Write full English sentences with proper capitalization and punctuation. Use the present tense. Use the imperative where applicable. For example: “Fix a bug in mbedtls_xxx() ….”
Include GitHub issue numbers where relevant. Use the format “#1234” for an Mbed TLS issue. Add other external references such as CVE numbers where applicable.
Credit bug reporters where applicable.
Explain why, not how. Remember that the audience is the users of the library, not its developers. In particular, for a bug fix, explain the consequences of the bug, not how the bug was fixed. For a new feature, explain why one might be interested in the feature. For an API change or a deprecation, explain how to update existing applications.
See existing entries for examples.
