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

106 * Many APIs around the dirstate have been made much stricter with regards to

110 something wrong.
111
112 == Miscellaneous ==
113
114 * pullbundle support no longer requires setting a server-side option,
115 providing a .hg/pullbundles.manifest according to the syntax specified in

118 * delta-find: add debug information about reuse of cached data
119 * delta-find: set the default candidate chunk size to 10
120 * attr: vendor 22.1.0

122 * debugrevlog: display total stored information
123 * emitrevision: if we need to compute a delta on the fly, try p1 or p2 first
124 * emitrevision: consider ancestors revision to emit as available base
125 * find-delta: pass the cache-delta usage policy alongside the cache-delta
