This version mostly includes bugfixes and stdlib improvement since 1.0. 1.1.0 has been immediately followed by 1.1.1, because of a missing README issue on the new nickel-lang-cli crate published to crates.io. Because crates on crates.io are immutable, we had to bump the minor version.
IMPORTANT: The main crate nickel-lang has been split between nickel-lang-cli (the binary) and nickel-lang-core (the library). If you're using cargo to install Nickel, please uninstall the previous crate by running cargo uninstall nickel-lang, and from now one use cargo install nickel-lang-cli to install 1.1 and do further updates.
