protostuff-1.8.1-SNAPSHOT
- fix NPE for `delegates` on arrays (Issue 336)

protostuff-1.8.0 2022-03-12

- allow protostuff-runtime to work with java 9 and above
- handle invalid repeated/collection/map pojos during serialization (Issue 309)
- include class and field name in error msg for invalid repeated/collection/map pojos during serialization (Issue 309)

===========================

Improvements
------------

* [#105](https://github.com/protostuff/protostuff/pull/105): Add option for generating field maps with original field names `[generated code]`

Fixes
-----

* [#98](https://github.com/protostuff/protostuff/issues/98): Fix for messages with sparse/big `@Tag` values `[runtime schemas]`
* [#108](https://github.com/protostuff/protostuff/issues/108): Fix for default values in `java_bean_model` `[generated code]`
* [#107](https://github.com/protostuff/protostuff/issues/107): Getter of optional enum should return `null` if not set `[generated code]`

Compatibility notes
-------------------

* Please check https://github.com/protostuff/protostuff/issues/107 as it changes structure of the schema, generated by `java_bean`. Now default values are not applied automatically for all field types, unless default value is specified explicitly. 
If you use protobuf as a serialization format, you should always do check for `null` and treat `null` as a default value. For example, you can use Guava's utility method: `MoreObjects.firstNonNull(message.getNullableFieldValue(), DEFAULT_FIELD_VALUE)`.

  - thanks to eedzjee
+ Issue 153: YamlOutput bug on repeated message fields
+ Issue 151: optimize xml format
+ Issue 141: protostuff ser/der can not keep order of elements in an array which contain null value
  - thanks to lzh0379
+ Issue 119: Reflection-based array operations are rather expensive

protostuff-1.0.8 2013-12-10
===========================

+ Issue 140: Multiple runtime schema contexts (IdStrategy groups)

+ Issue 133: When the varint of large strings (2kb or more) are serialized, unnecessary bytes are written
  A 2kb string previously needed 3 bytes for its varint.
  Now anything under 16kb will only need 2 bytes.
  This is a bug that was overlooked but doesn't have major side effects because of the way varint encoding works.
+ Issue 131: option can't be used as a field name in maven-plugin

protostuff-1.0.6 2012-05-14
===========================

+ allow @Tag annotations to override the field name
  - E.g @Tag(value=1, alias="foo")
  - useful for non-binary formats like json/xml/yaml
+ added Delegate, which handles ser/deser for:
  - singletons
  - pojos with no fields
  - pojos that should not be merged
  - could be used to encode a type to a byte array and write it (for example packing an int[] to a byte[])
+ added @Morph field annotation, which overrides:
  -Dprotostuff.runtime.morph_non_final_pojos
  -Dprotostuff.runtime.morph_collection_interfaces (new)
  -Dprotostuff.runtime.morph_map_interfaces (new)

  * removes recursion and uses a loop instead

protostuff-1.0.5 2012-03-31

  To optimize polymorphic ser/deser, use abstract classes or atleast declare the base abstract class.
+ add support for annotations on protostuff-runtime to have explicit control of field numbers (patch by Brice Jaglin).
  Annotate all non-transient/non-static fields with @Tag(x) or none at all (all or nothing).
+ Issue 77: RuntimeSchema.getSchema on Android and Server (the solution is to use @Tag annotations)
+ Issue 86: Is RuntimeSchema.createFrom safe (the solution is to use @Tag annotations)
+ Issue 106: Use Double.doubleToRawLongBits (was Double.doubleToLongBits) on serialization (protostuff-core)
  * Not applicable to protostuff-me since the method Double.doubleToRawLongBits does not exist on j2me api
+ new protostuff-runtime-registry module (compact ids for your polymorphic pojos)
+ Issue 105: ObjectSchema needs to check clazz.getSuperclass().isEnum() to detect complex enums
+ Issue 88: Add support for transparent handling of non-standard collections
+ Issue 96: user definable mapping: FQNC's --> integer, for serialized stream size-reduction (thanks to Leo Romanoff)

protostuff-1.0.4 2011-10-24
===========================

+ Issue 90: byte arrays on protostuff-runtime were not treated as scalar fields
            Best to update to this version for performance reasons.
            If you have existing data that came from a pojo with byte[] fields, it will not be compatible on deser.
            You can safely update the data by deserializing with the old protostuff from a different classloader 
            and writing it back again using the new protostuff on another classloader.

===========================

+ new protostuff-me module (for j2me by Michael Donohue)

  api+core works fine but this is for those who prefer runtime schemas.
+ Issue 73: Remove unused enum default value from java_bean generated code
+ Issue 70: Use FQCN everywhere in classes generated by java_v2protoc_schema
