Release 1.0.0
**Incompatible Changes**
- @bazel_skylib//:lib.bzl is removed. You now must specify specific modules
via @bazel_skylib//lib:<file>.bzl.
- maprule.bzl is removed.
**New Features**
- Added types.is_set() to test whether an arbitrary object is a set as defined by sets.bzl.
Release 0.9.0
**New Features**
- common_settings.bzl: Standard data types for user defined build
configuration. Common scalar build settings for rules to use so they don't
recreate them locally. This fulfills part of the SBC design doc:
https://docs.google.com/document/d/1vc8v-kXjvgZOdQdnxPTaV0rrLxtP2XwnD2tAZlYJOqw/edit#bookmark=id.iiumwic0jphr
- selects.bzl: Add config_setting_group for config_setting AND/OR-chaining
Implements
https://github.com/bazelbuild/proposals/blob/master/designs/2018-11-09-config-setting-chaining.md.
- Make sets.bzl point to new_sets.bzl instead of old_sets.bzl. new_sets.bzl
and old_sets.bzl should be removed in the following skylib release.
- run_binary: runs an executable as an action
- This rule is an alternative for genrule(): it can run a binary with the
desired arguments, environment, inputs, and outputs, as a single build
action, without shelling out to Bash.
- Fixes https://github.com/bazelbuild/bazel-skylib/issues/149
- New `native_binary()` and `native_test()` rules let you wrap a pre-built
binary in a binary and test rule respectively.
- native_binary() wraps a pre-built binary or script in a *_binary rule
interface. Rules like genrule can tool-depend on it, and it can be
executed with "bazel run". This rule can also augment the binary with
runfiles.
- native_test() is similar, but creates a testable rule instead of a
binary rule.
- Fixes https://github.com/bazelbuild/bazel-skylib/issues/148
- diff_test: test rule compares two files and passes if the files match.
On Linux/macOS/non-Windows, the test compares files using 'diff'.
On Windows, the test compares files using 'fc.exe'. This utility is
available on all Windows versions I tried (Windows 2008 Server, Windows 2016
Datacenter Core).
See https://github.com/bazelbuild/bazel/issues/5508,
https://github.com/bazelbuild/bazel/issues/4319
- maprule: move functionality to maprule_util.bzl. maprule_util.bzl will
benefit planned new rules (namely a genrule alternative).
**This release is tested with Bazel 0.28**
