2015-05-25 version 3.0.0-alpha-3 (Objective-C/C#):
|
|
|
General
|
|
|
* Introduced two new language implementations (Objective-C, C#) to proto3.
|
|
|
- * Disallowed "optional" keyword in proto3 syntax.
|
|
|
- * Removed groups fields in proto3 syntax.
|
|
|
+ * Explicit "optional" keyword are disallowed in proto3 syntax, as fields are
|
|
|
+ optional by default.
|
|
|
+ * Group fields are no longer supported in proto3 syntax.
|
|
|
* Changed repeated primitive fields to use packed serialization by default in
|
|
|
proto3 (implemented for C++, Java, Python in this release). The user can
|
|
|
still disable packed serialization by setting packed to false for now.
