 == Backwards Compatibility Changes ==
  * rust: upgrade supported Rust toolchain version

 == Internal API Changes ==
 
  * Many APIs around the dirstate have been made much stricter with regards to
    locking and transaction handling
  * Some dirstate APIs have been renamed/removed
  * In both cases, you should get loud complaints in your tests if you do
    something wrong.

    providing a .hg/pullbundles.manifest according to the syntax specified in
    'hg help -e clonebundles' is enough.

  * attr: vendor 22.1.0
