Comment thread
Copilot marked this conversation as resolved.
Outdated

### Fixed

- Corrected plant carbon accounting so the accounting-only carbon delta is not treated as nitrogen-bearing woody biomass (#359).
- Corrected nitrogen resorption and storage accounting during senescence and negative growth, including the ordering of storage use, fixation, and uptake (#359).
- Corrected the nitrogen mass-balance sign convention (#359).

### Changed

- Renamed the CLI option `--file-name` to `--file-prefix` for clarity while keeping `--file-name` as a backward-compatible alias (#320)

how do we make sure that this is up to date when we tag the release?

I don't usually see SHAs listed in changelogs at all (certainly I see them in, say, release announcement emails, but those are a different beast that lives outside the repo). What's the intended use case here that a tag doesn't handle?

Also the entries for releases 2.1.0 and 2.0.0 below still list the SHA as "[TBD]", which seems to me like an indication we don't really need it
