## UNRELEASED

# 1.18.0 - 2022-11-01

### Features :star:

- Add the `state_based` mode for DB pollers.

### Fixes :wrench:
- Fix the mock schema backend's `encode_key` method so it doesn't crash when used in application code.

# 1.17.1 - 2022-10-20

- Fix the log message for publishing messages so it uses the topic of the actual message instead of 
  the default for the producer.
- Use public sord gem instead of private fork.

# 1.17.0 - 2022-10-19
- Fix the linting step in the CI
- CHANGE: Add retries to DB poller and bypass "bad batches".
- Add tracing spans to DB poller production.

# 1.16.4 - 2022-09-09

- Now generates RBS types.
- Use `allocate` instead of `new` in `tombstone` to avoid issues with required fields in `initialize`.

# 1.16.3 - 2022-09-08

- Add the `tombstone` method to schema classes.

# 1.16.2 - 2022-09-07

- Added support of post_process method in ActiveRecordProducer

# 1.16.1 - 2022-08-03

- Fix issues with `enum` schema classes (e.g. equality not working, `to_s` not working)
- Changed assumption in the base schema class that it was a record (e.g. defining `to_h` instead of `as_json`). Moved record functionality to the record base class.
- Added the `active_span` and `set_tag` methods to the tracing classes.
- Added span tags for fields in SchemaControllerMixin.
- Updated SchemaControllerMixin so it works with generated schema classes.
- Fixed bug with previous release where the filename and constant names for `generate_namespace_folders` did not always match.

# 1.15.0 - 2022-07-20

- Update to `sigurd` 0.1.0 - DB producer should now exit when receiving a `SIGTERM` instead of throwing a `SignalException`

# 1.14.6 - 2022-06-21

- Add `generate_namespace_folders` to configuration; this will automatically generate subfolders to the `schemas` folder so that you can have different schemas with the same name but different namespaces generate separate classes.

# 1.14.5 - 2022-06-21

- Fix crash with the tracer when error happens in decoding a message during batch consuming
- Generate schema classes for all schemas, even without a consumer/producer set

# 1.14.1 - 2022-05-25

- Fix: When using key schemas, ActiveRecordConsumers were not finding the record by default.

# 1.14.0 - 2022-05-16

- **Breaking Change**: Nest sub-schemas by default into their parent schemas when generating classes.
- Add the `nest_child_schemas` option to essentially bring back the previous behavior in terms of code use (the actual classes will be separated out into different files).

# 1.13.3 - 2022-05-10

- Some cleanup on the active_record generator
- Fix crash with `test_consume_message` when using schema classes
- Add `[]=` and `merge` methods on the base schema class
