Subteam report: tools 2016-04-25

Highlights

The following RFCs were accepted this past week:

• RFC 1510 - Adding a new crate type of cdylib for "C-like dynamic libraries"

• RFC 1535 - Adding a stable -C overflow-checks flag to the compiler.

Similarly, another RFC in FCP was debated, but not quite merged yet. Feedback is always appreciated!

• RFC 1525 - Adding workspaces to Cargo.

Otherwise, some notable PRs this week were:

• Rust 1.8 was released! Thanks again to @steveklabnik for the blog post, @brson for preparing the release artifacts, and of course the whole community for the excellent release!

• The rustbuild build system continues forward with support for tidy, ninja support, verifying downloads, compiletest test suites (aka run-pass, compile-fail, etc), and markdown tests.

• Rust now bootstraps from the previous stable release instead of from an arbitrary snapshot. This means that the 1.10 compiler will bootstrap from the release 1.9 compiler.

• Cargo now exposes authors to compiled crates through CARGO_PKG_AUTHORS.

• The cargo doc command [now supports][doclib] --lib and --bin flags and cargo test similarly supports a --doc option now.
