|
== Backwards Compatibility Changes ==
|
|
|
|
|
|
Users of the Rust extensions and/or `rhg` should be aware that the new Rust
|
|
|
index can result in a performance degradation for push/pull on repositories
|
|
|
*not* using `persistent-nodemap` (see `hg help config.format.use-persistent-nodemap`).
|
|
|
|
|
|
If this is something that matters to you, please reach out to us as this is not
|
|
|
an insurmountable obstacle. This is a choice base on the assumption that
|
|
|
there are few people in this situation and our time should be spent on more
|
|
|
pressing matters.
