How to specify the exact version of a dependency?

I'm using

$ cargo --version
cargo 0.21.0-beta (7e00b82d9 2017-07-17)

I created a simple project with cargo new --bin test1, and then I added a dependency:

[dependencies]
lazy_static = "0.2.2"

to Cargo.toml (according to this such version exists) and

#[macro_use]
extern crate lazy_static;

to src/main.rs

When I run cargo build:

$ cargo build
   Compiling lazy_static v0.2.8
   Compiling test1 v0.1.0 (file:///tmp/test1)
warning: unused `#[macro_use]` import
 --> src/main.rs:1:1
  |
1 | #[macro_use]
  | ^^^^^^^^^^^^
  |
  = note: #[warn(unused_imports)] on by default

    Finished dev [unoptimized + debuginfo] target(s) in 0.49 secs

Why does cargo build compile last version 0.2.8 instead of 0.2.2 that I specified? What am I doing wrong?
