## in 2.7.0.0

- skalibs dependency bumped to 2.10.0.0.

- forstdin now exits 1 on immediate EOF, and only splits on newlines by default.

- Input-processing binaries (not substitution binaries!) now chomp by default.

- New `default` directive to trap, replacing the `timeout` one, which was ill-suited to that program.

## in 2.6.1.1

- skalibs dependency bumped to 2.9.3.0.

## in 2.6.1.0

- The envfile format has changed. It is now more expressive and largely compatible with systemd's EnvironmentFile format. The new format is a superset of the old one, so old envfiles should still be understood by the new binary.

## in 2.6.0.2

- No functional changes

## in 2.6.0.1

- skalibs dependency bumped to 2.9.2.1.

## in 2.6.0.0

- New binary: posix-umask.
- `cd` has been renamed execline-cd.
