# Changelog
|
|
|
|
Our releases are accompanied by changelogs based on the
|
|
[Keep a Changelog](https://keepachangelog.com/en/1.0.0/) format. We are using
|
|
the [towncrier](https://github.com/twisted/towncrier) utility to generate them
|
|
at the time a new version is released. There are currently 8 such changelogs
|
|
for different components of the repository:
|
|
|
|
* **[`core/CHANGELOG.md`](https://github.com/trezor/trezor-firmware/blob/master/core/CHANGELOG.md)** for Trezor T firmware
|
|
* **[`core/embed/boardloader/CHANGELOG.md`](https://github.com/trezor/trezor-firmware/blob/master/core/embed/boardloader/CHANGELOG.md)** for Trezor T boardloader
|
|
* **[`core/embed/bootloader/CHANGELOG.md`](https://github.com/trezor/trezor-firmware/blob/master/core/embed/bootloader/CHANGELOG.md)** for Trezor T bootloader
|
|
* **[`core/embed/bootloader_ci/CHANGELOG.md`](https://github.com/trezor/trezor-firmware/blob/master/core/embed/bootloader_ci/CHANGELOG.md)** for Trezor T CI bootloader
|
|
* **[`legacy/firmware/CHANGELOG.md`](https://github.com/trezor/trezor-firmware/blob/master/legacy/firmware/CHANGELOG.md)** for Trezor 1 firmware
|
|
* **[`legacy/bootloader/CHANGELOG.md`](https://github.com/trezor/trezor-firmware/blob/master/legacy/bootloader/CHANGELOG.md)** for Trezor 1 bootloader
|
|
* **[`legacy/intermediate_fw/CHANGELOG.md`](https://github.com/trezor/trezor-firmware/blob/master/legacy/intermediate_fw/CHANGELOG.md)** for Trezor 1 intermediate firmware
|
|
* **[`python/CHANGELOG.md`](https://github.com/trezor/trezor-firmware/blob/master/python/CHANGELOG.md)** for Python client library

## Adding changelog entry
|
|
|
|
[`towncrier`](https://github.com/twisted/towncrier) aims to create changelogs
|
|
that are convenient to read, at the expense of being somewhat inconvenient to
|
|
create.
|
|
|
|
Furthermore every changelog entry should be linked to a GitHub issue or pull
|
|
request number. If you don't want to create an issue just to satisfy this rule
|
|
you can use self-reference to your change's pull request number by first
|
|
creating the PR and then adding the entry. If this is not suitable, the word
|
|
`noissue` can be used in place of the issue number.
|
|
|
|
There are a few types of changelog entries, as described by the [Keep a
|
|
Changelog](https://keepachangelog.com/en/1.0.0/) format:
|
|
|
|
* `added`
|
|
* `changed`
|
|
* `deprecated`
|
|
* `removed`
|
|
* `fixed`
|
|
* `security`
|
|
* `incompatible` (for backwards incompatible changes)
|
|
|
|
Entries are added by creating files in the `.changelog.d` directory where the
|
|
file name is `<number>.<type>` and contains single line describing the change.
|
|
As an example, an entry describing bug fix for issue 1234 in Trezor T firmware
|
|
is added by creating file `core/.changelog.d/1234.fixed`. The file can be
|
|
formatted with markdown. If more entries are desired for single issue number and
|
|
type you can add numeral suffix, e.g. `1234.fixed.1`, `1234.fixed.2`, etc.
|
|
|
|
You can also add this entry using your `$VISUAL` editor by running `towncrier
|
|
create --edit 1234.fixed` in the `core` directory.
|
|
|
|
### Changes that only affect a subset of hardware models
|
|
|
|
If an entry is only relevant for certain model, put the internal name in square
|
|
brackets at the beginning of the entry. If there are multiple relevant models,
|
|
separate them by comas. Examples: `[T2T1] Fix some bug.`, `[T2T1,T2W1] Fix all
|
|
bugs.`.
|
|
|
|
## Not adding changelog entry
|
|
|
|
If you don't add an entry for changes in your branch, the `changelog prebuild`
|
|
CI job will remind you by failing. Sometimes adding an entry does not really make
|
|
sense, in that case you can include `[no changelog]` anywhere in the commit
|
|
message to exclude that commit from the check.
|
|
|
|
## Generating changelog at the time of release
|
|
|
|
When it's time to release new version of a repository component the formatted
|
|
changelog needs to be generated using the `tools/generate-changelog.py` script.
|
|
It accepts repo subdirectory and the version number as arguments and you can
|
|
specify the release date if it's different from today's date:
|
|
|
|
```
|
|
tools/generate-changelog.py --date "20th April 2021" legacy/firmware 1.10.0
|
|
```
|
|
|
|
## Cherry-picking changes to release branch
|
|
|
|
Branches named `release/YY.MM` already have their corresponding `CHANGELOG.md`
|
|
section generated. When cherry-picking bug fix to such branch you need to
|
|
bypass towncrier and edit `CHANGELOG.md` directly.
