### [`v2.6.2`](https://togithub.com/google/gson/blob/HEAD/CHANGELOG.md#Version-262)
*2016-02-26* [GitHub Diff](https://togithub.com/google/gson/compare/gson-parent-2.6.1...gson-parent-2.6.2)
- Fixed an NPE bug with [@JsonAdapter](https://togithub.com/JsonAdapter) annotation
- Added back OSGI manifest
- Some documentation typo fixes
### [`v2.6.1`](https://togithub.com/google/gson/blob/HEAD/CHANGELOG.md#Version-261)
*2016-02-11* [GitHub Diff](https://togithub.com/google/gson/compare/gson-parent-2.6...gson-parent-2.6.1)
- Fix: The 2.6 release targeted Java 1.7, but we intend to target Java 1.6. The
2.6.1 release is identical to 2.6, but it targets Java 1.6.
### [`v2.6`](https://togithub.com/google/gson/blob/HEAD/CHANGELOG.md#Version-262)
*2016-02-26* [GitHub Diff](https://togithub.com/google/gson/compare/gson-parent-2.6.1...gson-parent-2.6.2)
- Fixed an NPE bug with [@JsonAdapter](https://togithub.com/JsonAdapter) annotation
- Added back OSGI manifest

### [`v2.5`](https://togithub.com/google/gson/blob/HEAD/CHANGELOG.md#Version-25)
*2015-11-24* [GitHub Diff](https://togithub.com/google/gson/compare/gson-parent-2.4...gson-parent-2.5)
- Updated minimum JDK version to 1.6
- Improved Date Deserialization by accepting many date formats
- Added support for `java.util.Currency`, `AtomicLong`, `AtomicLongArray`, `AtomicInteger`, `AtomicIntegerArray`, `AtomicBoolean`. This change is backward-incompatible because the earlier version of Gson used the default serialization which wasn't intuitive. We hope that these classes are not used enough to actually cause problems in the field.
- Improved debugging information when some exceptions are thrown
### [`v2.4`](https://togithub.com/google/gson/blob/HEAD/CHANGELOG.md#Version-24)
*2015-10-04*
- **Drop `IOException` from `TypeAdapter.toJson()`.** This is a binary-compatible change, but may
cause compiler errors where `IOExceptions` are being caught but no longer thrown. The correct fix
for this problem is to remove the unnecessary `catch` clause.
- New: `Gson.newJsonWriter` method returns configured `JsonWriter` instances.
- New: `@SerializedName` now works with \[AutoValue’s]\[autovalue] abstract property methods.
- New: `@SerializedName` permits alternate names when deserializing.
- New: `JsonWriter#jsonValue` writes raw JSON values.
- New: APIs to add primitives directly to `JsonArray` instances.
- New: ISO 8601 date type adapter. Find this in *extras*.
- Fix: `FieldNamingPolicy` now works properly when running on a device with a Turkish locale.
\[autovalue]: https://togithub.com/google/auto/tree/main/value
### [`v2.3.1`](https://togithub.com/google/gson/blob/HEAD/CHANGELOG.md#Version-231)
*2014-11-20*
- Added support to serialize objects with self-referential fields. The self-referential field is set to null in JSON. Previous version of Gson threw a StackOverflowException on encountering any self-referential fields.
- The most visible impact of this is that Gson can now serialize Throwable (Exception and Error)
- Added support for [@JsonAdapter](https://togithub.com/JsonAdapter) annotation on enums which are user defined types
- Fixed bug in getPath() with array of objects and arrays of arrays
- Other smaller bug fixes
### [`v2.3`](https://togithub.com/google/gson/blob/HEAD/CHANGELOG.md#Version-231)
*2014-11-20*
- Added support to serialize objects with self-referential fields. The self-referential field is set to null in JSON. Previous version of Gson threw a StackOverflowException on encountering any self-referential fields.
- The most visible impact of this is that Gson can now serialize Throwable (Exception and Error)
- Added support for [@JsonAdapter](https://togithub.com/JsonAdapter) annotation on enums which are user defined types
- Fixed bug in getPath() with array of objects and arrays of arrays
- Other smaller bug fixes
### [`v2.2.4`](https://togithub.com/google/gson/blob/HEAD/CHANGELOG.md#Version-224)
*2013-05-13*
- Fix internal map (LinkedHashTreeMap) hashing bug.
- Bug fix (Issue 511)
### [`v2.2.3`](https://togithub.com/google/gson/blob/HEAD/CHANGELOG.md#Version-223)
*2013-04-12*
- Fixes for possible DoS attack due to poor String hashing
### [`v2.2.2`](https://togithub.com/google/gson/blob/HEAD/CHANGELOG.md#Version-222)
*2012-07-02*
- Gson now allows a user to override default type adapters for Primitives and Strings. This behavior was allowed in earlier versions of Gson but was prohibited started Gson 2.0. We decided to allow it again: This enables a user to parse 1/0 as boolean values for compatibility with iOS JSON libraries.
- (Incompatible behavior change in `JsonParser`): In the past, if `JsonParser` encountered a stream that terminated prematurely, it returned `JsonNull`. This behavior wasn't correct because the stream had invalid JSON, not a null. `JsonParser` is now changed to throw `JsonSyntaxException` in this case. Note that if JsonParser (or Gson) encounter an empty stream, they still return `JsonNull`.
### [`v2.2.1`](https://togithub.com/google/gson/blob/HEAD/CHANGELOG.md#Version-221)
*2012-05-05*
- Very minor fixes
### [`v2.2`](https://togithub.com/google/gson/blob/HEAD/CHANGELOG.md#Version-224)
*2013-05-13*
- Fix internal map (LinkedHashTreeMap) hashing bug.
- Bug fix (Issue 511)
