prost: Remove prost-derive feature (#1247)

BREAKING CHANGE: Feature flag prost-derive is renamed to derive. Please rename any usage of prost-derive feature in your Cargo.toml.

prost-build: Emit rerun commands (#1140)

BREAKING CHANGE: Previously cargo assumed it had to rerun build.rs if any files in the project changed. prost-build will now emit rerun commands, which means only the explicitly marked files cause a rerun. If your build.rs is dependent on any other file paths than those given to prost-build, then your build.rs needs to emit rerun commands as well.

prost-build: Prevent repeated fields to be boxed (#1237)

BREAKING CHANGE: A repeated field that is manually marked as boxed was typed as Vec<Box<T>>. Those fields are now simply typed as Vec<T> to prevent double indirection. The boxed configuration is effectively ignored for repeated fields.

prost-build: Make type_name_domain cumulative (#1228)

BREAKING CHANGE: The configuration for domain names of messages is now cumulative. All calls to prost_build::Config::type_name_domain are now concatenated. The previous behavior was that only the arguments of the last call were used. If you do multiple calls to type_name_domain, you need to remove all but the last call to maintain the same behavior.

prost-build: Derive Eq and Hash trait for messages where possible (#1175)

BREAKING CHANGE: prost-build will automatically derive trait Eq and trait Hash for types where all field support those as well. If you manually impl Eq and/or impl Hash for generated types, then you need to remove the manual implementation. If you use type_attribute to derive(Eq) and/or derive(Hash), then you need to remove those.
