1.0.49

• Add a function anyhow::Ok(v) equivalent to Ok::<_, anyhow::Error>(v) (#192)

1.0.48

• Include a Debug rendering of lhs and rhs in ensure! messages (#193, #194, #195, #196, #197, #198)

  Example:

  ensure!(flags.len() <= 40);

  ensure!(kind == Kind::File);

  Before:

  Condition failed: `flags.len() <= 40`
  Condition failed: `kind == Kind::File`

  After:

  Condition failed: `flags.len() <= 40` (99 vs 40)
  Condition failed: `kind == Kind::File` (Symlink vs File)

1.0.47

• Fixes for implicit format args support

1.0.46

• Support for implicit format args to match println and other std macros (https://rust-lang.github.io/rfcs/2795-format-args-implicit-identifiers.html)

  let var = ...;
  let error = anyhow!("interpolate {var}");  // equivalent to anyhow!("interpolate {var}", var=var)

• Detect missing fmt arguments at compile time: anyhow!("{} not found") (#55)

• Reduce occurrence of "future cannot be shared between threads safely" in async code using anyhow macros (#186)

1.0.45

• Fix non-compilable macro expansion if downstream crate calls anyhow!, ensure!, or bail! with format args and is built with #![no_std] or #![no_implicit_prelude] (#177)

1.0.44

• Mark error constructors cold to help LLVM optimize code paths not leading to error (#166, thanks @stepancheg)

1.0.43

• Take -Zallow-features restrictions from Cargo configuration file into account on sufficiently new versions of nightly Cargo (#157, thanks @jonhoo)

1.0.42

• Enable Android's automated tooling to pull in test coverage improvements

1.0.41

• Disallow incompatible old versions of backtrace crate (#155, thanks @jfirebaugh)

1.0.40

• Reduce memory footprint of errors on Rust versions 1.51+ (#145)
