## v0.26.0

02-28-2019 05:42 PST

### BREAKING: `message.publishTime` is now represented by a [`PreciseDate`](https://github.com/googleapis/nodejs-precise-date) object. ([#503](https://github.com/googleapis/nodejs-pubsub/pull/503))

The `PreciseDate` class extends the native Date object, so most users should be unaffected by this change. The notable differences between PreciseDate and Date objects are:

- `toISOString()` now returns as a RFC 3339 formatted string.
- Nano and microsecond data is available via `date.getNanoseconds()` and `date.getMicroseconds()` respectively.

### New Features
- feat(typescript): ship typescript declaration files ([#498](https://github.com/googleapis/nodejs-pubsub/pull/498))
- feat(subscription): support push config auth methods ([#504](https://github.com/googleapis/nodejs-pubsub/pull/504))

### Internal / Testing Changes
- refactor(typescript): noImplicitAny for snapshot and subscriber test file ([#490](https://github.com/googleapis/nodejs-pubsub/pull/490))
- fix(messageStream): remove call to destroy grpc stream ([#499](https://github.com/googleapis/nodejs-pubsub/pull/499))

02-20-2019 10:35 PST

### Implementation Changes

The retry logic for **all** methods has changed. It is possible that this could go unnoticed, however if you suddenly start seeing errors in places that were previously quiet, this might account for said errors.

### New Features
- refactor(ts): improve TypeScript types ([#482](https://github.com/googleapis/nodejs-pubsub/pull/482))
- refactor(typescript): noImplicityAny for snapshot.ts and publisher.ts ([#457](https://github.com/googleapis/nodejs-pubsub/pull/457))

## v0.23.0

01-16-2019 13:09 PST

**This release has breaking changes.**

#### BREAKING: `Topic#publisher()` has been removed in favor of `Topic#publish()` ([#426](https://github.com/googleapis/nodejs-pubsub/pull/426))

Before
```js
const publisher = topic.publisher(publishOptions);
await publisher.publish(Buffer.from('Hello, world!'));
```

After
```js
topic.setPublishOptions(publishOptions);
await topic.publish(Buffer.from('Hello, world!'));
```

#### BREAKING: `Subscription` options have changed. ([#388](https://github.com/googleapis/nodejs-pubsub/pull/388))

Before
```js
const subscription = topic.subscription('my-sub', {
  batching: {
    maxMilliseconds: 100,
  },
  flowControl: {
    maxBytes: os.freem() * 0.2,
    maxMessages: 100,
  },
  maxConnections: 5,
});
```

After
```js
const subscription = topic.subscription('my-sub', {
  ackDeadline: 10,
  batching: {
    callOptions: {}, // gax call options
    maxMessages: 3000,
    maxMilliseconds: 100,
  },
  flowControl: {
    allowExcessMessages: true,
    maxBytes: os.freem() * 0.2,
    maxExtension: Infinity,
    maxMessages: 100
  },
  streamingOptions: {
    highWaterMark: 0,
    maxStreams: 5, // formerly known as maxConnections
    timeout: 60000 * 5, // 5 minutes
  }
});
```

#### BREAKING: messages are no longer plain objects. ([#388](https://github.com/googleapis/nodejs-pubsub/pull/388))

Messages were refactored into a [class](https://github.com/googleapis/nodejs-pubsub/blob/52305c7ee5bbc9caba1369a45ae7fdcdeba1c89b/src/subscriber.ts#L59),
this will only affect (some) users who treat messages like plain old objects.

The following example is something that would have worked previously, but will
now throw a `TypeError` since `ack` lives on the prototype chain.

```js
const m = Object.assign({}, message, customData);
m.ack(); // TypeError: m.ack is not a function
```
