# 1.0.2.0
- `--blank-project` is a new mode for building packages directly from hackage,
and is a much faster alternative to `--install-lib`. It works by creating a
temporary `cabal.project` file, whose contents are simply
```
extra-packages: target1, target2, ...
```
This causes `target1`... to be interpreted as simultaneously a package to be
downloaded from hackage, and a package to be considered local, i.e. included
in the "build" step and excluded from the "deps" step.
- `--constraints` is a new option for specifying build constraints. It allows
specifying one or more constraints on package versions with
`--constraints "foo >1 , bar <2"`. It also allows specifying implication
constraints such as `--constraints "foo >1 :- bar <2"` e.g. as if all versions
`foo >1` were revised to include a `bar <2` constraint. More generally it
allows specifying disjunction constraints separated with `;`, such as
`--constraints "foo >1 ; bar <2 ; baz ==3"`. Disjunction/implication
constraints are translated to constraints guarded behind automatic cabal
flags.
# 1.0.1.0
- Binary operator options can now be parsed/formatted as JSON in a more compact
way: `foo --times bar --times baz` can now be serialized/deserialized as
`{"times":[foo,bar,baz]}`
- `--package PACKAGE` (i.e. without any version or version range specified) now
stands for all versions of `PACKAGE`. Likewise in JSON
`{"package":"PACKAGE","versions":null}` now stands for all versions.
- In the TUI, a build can now be:
- interrupted with Ctrl+C
- terminated with Ctrl+\
- prioritized with P
- restarted with R
