Protocol Buffers v3.20.3

Java

• Refactoring java full runtime to reuse sub-message builders and prepare to migrate parsing logic from parse constructor to builder.
• Move proto wireformat parsing functionality from the private "parsing constructor" to the Builder class.
• Change the Lite runtime to prefer merging from the wireformat into mutable messages rather than building up a new immutable object before merging. This way results in fewer allocations and copy operations.
• Make message-type extensions merge from wire-format instead of building up instances and merging afterwards. This has much better performance.
• Fix TextFormat parser to build up recurring (but supposedly not repeated) sub-messages directly from text rather than building a new sub-message and merging the fully formed message into the existing field.
• This release addresses a Security Advisory for Java users

Protocol Buffers v3.20.2

C++

• Reduce memory consumption of MessageSet parsing
• This release addresses a Security Advisory for C++ and Python users

Protocol Buffers v3.20.1

PHP

• Fix building packaged PHP extension (#9727)
• Fixed composer.json to only advertise compatibility with PHP 7.0+. (#9819)

Ruby

• Disable the aarch64 build on macOS until it can be fixed. (#9816)

Other

• Fix versioning issues in 3.20.0

Protocol Buffers v3.20.1-rc1

Protocol Buffers v3.20.0

2022-03-25 version 3.20.0 (C++/Java/Python/PHP/Objective-C/C#/Ruby/JavaScript)

Ruby

• Dropped Ruby 2.3 and 2.4 support for CI and releases. (#9311)
• Added Ruby 3.1 support for CI and releases (#9566).
• Message.decode/encode: Add recursion_limit option (#9218/#9486)
• Allocate with xrealloc()/xfree() so message allocation is visible to the Ruby GC. In certain tests this leads to much lower memory usage due to more frequent GC runs (#9586).
• Fix conversion of singleton classes in Ruby (#9342)
