## Changes, compatibility

### JDK

No changes from [2.8](Jackson-Release-2.8.md): Java 7 features available for all modules (meaning, need to compile on Java 7), JDK/JVM 7 is the baseline, except:

* `jackson-annotations`, `jackson-core` (streaming) and `jackson-jr` still only require JDK/JVM 6
* Java 8 modules, Kotlin, Scala module require JDK/JVM 8

Other modules could theoretically run on Java 6 with reduced features (i.e. avoid loading Java 7 types), but have compiled compiled with `-target 1.7` setting so bytecode unfortunately requires JDK 7.
It should be possible to post-process jars, however, to produce JDK 6 - compatible jars.

### Android

No changes: similar to Jackson 2.8 minimum is `Android 4.4`, API-level `19` (see [this dashboard](https://developer.android.com/about/dashboards/index.html) for example).

Note that version `2.7` will work with older Android versions; and there are some reports that even `2.8` may actually work (even if not specified to).

## New Modules, status changes

### Dataformat: Ion

First official version of `jackson-dataformat-ion` (under `jackson-dataformats-binary` repo) supports [Amazon Ion](https://amznlabs.github.io/ion-docs/) binary data format.

### Changes: compatibility

#### `java.sql.Date`

As per [databind#219](https://github.com/FasterXML/jackson-databind/issues/219) `java.sql.Date` will finally use same "timestamp-or-String" determination as `java.util.Date` and `java.util.Calendar`.
This means that with vanilla, unchanged settings, values will be serialized as numeric timestamps.
Note that the default String serialization will still default to `java.sql.Date.String()`, and not to default formatting `java.util.Date` uses.

## Major features of 2.9

### Implemented

1. Add separate exception type for "pojo configuration problem" (`InvalidDefinitionException`), distinct from "json input" problem (`MismatchedInputException`); in general to distinguish between bad configuration (server-side issue) and bad data (client issue) [#1356](https://github.com/FasterXML/jackson-databind/issues/1356)
2. Per-property custom serialization inclusion (`@JsonInclude(value=Include.CUSTOM, valueFilter=MyExcluder.class`) [#888](https://github.com/FasterXML/jackson-databind/issues/888)
3. Per-property overwrite-vs-merge annotation/handling, to allow for merging of configuration information (for example) [#1399](https://github.com/FasterXML/jackson-databind/issues/1399)
    * note: on-going work to increase coverage; most types should work
4. Ability to override handling of `null` for deserialization [#1402](https://github.com/FasterXML/jackson-databind/issues/1402)
5. Aliases, to allow migration: alternate property id names to accept (but not write) [#1029](https://github.com/FasterXML/jackson-databind/issues/1029)
6. Non-blocking JSON/Smile parser [#57](https://github.com/FasterXML/jackson-core/issues/57)
7. `DeserializationFeature` to automatically verify that value bound is full value and there is no trailing junk in input ("whole value verification") [#1583](https://github.com/FasterXML/jackson-databind/issues/1583)


## Postponed Features

From original "big items" list, a few were left out:

1. Ability to force "inject-only" variant of `@JacksonInject` [#1381](https://github.com/FasterXML/jackson-databind/issues/1381) -- also solves a few related issues wrt un-deserializable injectable values (which are common)
2. Allow pre-defining Object Ids; pluggable Object Id converters? [#693](https://github.com/FasterXML/jackson-databind/issues/693)
3. Rewrite of property/creator introspection code, to resolve most open issues wrt Creator auto-detection and name-detection
    * NOTE: partial rewrite occurred for 2.12
4. A way to force a supertype as type id to use during serialization: this is needed to avoid deserialization problems for things like concrete Hibernate collection type. [#789](https://github.com/FasterXML/jackson-databind/issues/789)
5. Protobuf: Schema building by hand
6. "Safe" `ObjectReader`, `ObjectWriter`; that is, ones that does NOT throw checked exceptions (wrap `IOException`s), to work better with Java 8 Streams [#779](https://github.com/FasterXML/jackson-databind/issues/779)
    * NOTE: decided against this approach -- instead, Jackson 3.0 will change `JsonProcessingException` to be unchecked, to prevent need for "safe" alternative
7. Support for `@JsonIncludeProperties` (opposite of `@JsonIgnoreProperties`) [#1296](https://github.com/FasterXML/jackson-databind/issues/1296)
    * NOTE: finally implement in [Jackson 2.1](Jackson-Release-2.12.md)

In addition, during development of 2.9, couple of new great ideas surfaced, but could not yet be implemented due to time constraints:

* Low-level `String` post-processor? [jackson-core#355](https://github.com/FasterXML/jackson-core/issues/355)
* Comma-separated "ints in a String" [#1242](https://github.com/FasterXML/jackson-databind/issues/1242)
* Support for automated `FormatSchema` configuration/lookup: [#1582](https://github.com/FasterXML/jackson-databind/issues/1582)
    * Would be especially useful for cases where caller does not have full control; for example, when using as extension for frameworks like JAX-RS
* `@JsonUnwrapped` improvements, which need major rewrite of unwrapped deserialization:
    * Support for `@JsonUnwrapped` as `@JsonCreator` parameter
    * Catching "unknown" properties

Ideally the next minor version (or, as the case may be, major...) -- 3.0 -- would start by considering these features as the starting Big Ticket item list.
