Changelog
### 3.20.3
```
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](https://github.com/protocolbuffers/protobuf/security/advisories/GHSA-h4h5-3hr4-j3g2)
```
### 3.20.2

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)
* Suppress warning for intentional circular require (9556)
* JSON will now output shorter strings for double and float fields when possible
without losing precision.
* Encoding and decoding of binary format will now work properly on big-endian
systems.
* UTF-8 verification was fixed to properly reject surrogate code points.
* Unknown enums for proto2 protos now properly implement proto2's behavior of
putting such values in unknown fields.

* Pure python repeated scalar fields will not able to pickle. Convert to list
first.
* Timestamp.ToDatetime() now accepts an optional tzinfo parameter. If
specified, the function returns a timezone-aware datetime in the given time
zone. If omitted or None, the function returns a timezone-naive UTC datetime
(as previously).
* Adds client_streaming and server_streaming fields to MethodDescriptor.
* Add "ensure_ascii" parameter to json_format.MessageToJson. This allows smaller
JSON serializations with UTF-8 or other non-ASCII encodings.
* Added experimental support for directly assigning numpy scalars and array.
* Improve the calculation of public_dependencies in DescriptorPool.

Changelog
### 3.20.3 ``` 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](https://github.com/protocolbuffers/protobuf/security/advisories/GHSA-h4h5-3hr4-j3g2) ``` ### 3.20.2 ``` C++ * Reduce memory consumption of MessageSet parsing * This release addresses a [Security Advisory for C++ and Python users](https://github.com/protocolbuffers/protobuf/security/advisories/GHSA-8gq9-2x98-w8hf) ``` ### 3.20.1 ``` 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.

(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) * Suppress warning for intentional circular require (9556) * JSON will now output shorter strings for double and float fields when possible without losing precision. * Encoding and decoding of binary format will now work properly on big-endian systems. * UTF-8 verification was fixed to properly reject surrogate code points. * Unknown enums for proto2 protos now properly implement proto2's behavior of putting such values in unknown fields. Java * Revert "Standardize on Array copyOf" (9400) * Resolve more java field accessor name conflicts (8198) * Don't support map fields in DynamicMessage.Builder.{getFieldBuilder,getRepeatedFieldBuilder} * Fix parseFrom to only throw InvalidProtocolBufferException * InvalidProtocolBufferException now allows arbitrary wrapped Exception types. * Fix bug in `FieldSet.Builder.mergeFrom` * Flush CodedOutputStream also flushes underlying OutputStream * When oneof case is the same and the field type is Message, merge the subfield.

Convert to list first. * Timestamp.ToDatetime() now accepts an optional tzinfo parameter. If specified, the function returns a timezone-aware datetime in the given time zone.
