2.7.0

Released 2026-08-20Minor releasePrevious 2.6.2, 2026-07-23

Profiles, a lint pass and the ability to apply one patch without rebuilding the series. This is the release that made the tool comfortable to use every day rather than once per fork.

Added

• Configuration profiles: named override blocks in bep.toml, selected with --profile or BEP_PROFILE. A profile sets jobs, target and apply flags for a machine or a CI runner.
• bep series lint checks every header, reports overlapping touches prefixes and refuses duplicate ids.
• bep apply --patch ID applies one patch and its dependencies. With --from-scratch it rebuilds the tree first, which is the only honest way to test a patch that deletes lines.
• bep config show prints each resolved value with its source.

Changed

• The lockfile moved to version 2 and stores a hash per patch. A series whose patch changed after the last apply now fails the stale-lock check before touching the tree.
• The minimum Rust version is 1.79.
• bep apply --dry-run resolves dependencies before printing the plan, so the plan matches the real run.

Fixed

• A series.toml saved with CRLF was parsed as one long line.
• bep config check panicked when a profile named in the file did not exist, instead of listing the names that do.
• Applying a series with a single patch printed a dependency summary with an empty list.

Known issues

• Lockfiles written by 2.6 are read once and upgraded; the upgrade warning cannot be suppressed.
• Profiles do not merge nested keys. Setting build in a profile replaces the whole block; use flat keys as in the examples.

Upgrade notes

No migration command is needed. Run bep apply once after replacing the binary to rewrite the lockfile with per-patch hashes, and commit the change. If you keep scripts that parse apply --dry-run output, check the plan line: it now lists dependencies above the patches that requested them, so the ordering of lines changed, though the format did not.
