Poetry 1.2 introduced dependency groups. [tool.poetry.group.dev.dependencies] is the modern spelling and [tool.poetry.dev-dependencies] is the deprecated alias for the group named dev. Arbitrary groups are allowed, so test, docs and lint can be separate.
The CLI changed with it. --no-dev was removed; the equivalents are poetry install --without dev, --with docs to add an optional group, and --only main to install nothing but the runtime dependencies. A script that still passes --no-dev fails with an unknown option error rather than silently doing the old thing.
Groups are installed by default unless marked optional = true in their group table, which is the piece people miss: adding a docs group does not make it opt-in automatically, and every developer gets Sphinx until you mark it optional and then request it with --with docs. For a production image, poetry install --only main --no-root gives the smallest environment.
