[tseaver]

Given that there are a couple of new features, as well as some backward-incompatible changes, I think this release needs to be 0.6, rather than 0.5.1.

[dhermes]

This is my plan for the release notes on the tag:

### General
-   Adding `from_service_account_json`, `from_service_account_p12`
    and `from_environment` factories to `Connection` base class.
    This allows creating a connection without first creating a
    set of credentials.

### Datastore
-   Fixing serious bug where the transaction ID was not passed
    along to transactions, effectively making a transaction act as
    a batch.
-   Adding scope to un-scoped credentials passed to connection
    constructor.
-   Enabling connection as an optional argument to all methods
    and functions which use a connection.
-   Requiring `exclude_from_indexes` to be a tuple or list in
    `Entity` constructor.
-   Requiring `projection`, `order` and `group_by` to be a
    tuple or list in `Query` constructor.
-   Re-purposing `datastore.get` to take a single key and moving
    previous functionality to `datastore.get_multi`. Similar
    changes were made for

    ```
    datastore.put --> datastore.put_multi
    ```

    and

    ```
    datastore.delete --> datastore.delete_multi
    ```

### Storage
-   Adding futures in to allow GET/PATCH to
    work correctly in a batch.
-   Remove default chunk size in upload/download.
-   Adding lazy loaded default connection and project.
-   Decoupling connection property from `Blob`/`ACL`/`Bucket`
    classes.
-   Enabling connection as an optional argument to all methods
    and functions which use a connection.
-   Adding scope to un-scoped credentials passed to connection
    constructor.
-   Updating public blob URL to use `storage.googleapis.com`.
-   Remove `Bucket.__iter__` and `Bucket.__contains__`.
-   Limiting `Bucket.make_public(recursive=True)` to cowardly refuse
    if more than 256 objects are in the bucket. This is similar to
    what is done in `Bucket.delete(force=True)`.

### Pub/Sub
-   Auto-adding timestamp to messages.
-   Adding an optional message timestamp so that
    messages can be sorted.
-   Adding scope to un-scoped credentials passed to connection
    constructor.
-   Enabling connection as an optional argument to all methods
    and functions which use a connection.
-   Fixing bug in `Subscription.pull` for cases when `receivedMessages`
    is not returned.

@tseaver Please give this some extra scrutiny, I'm a bit unsure of some parts.

[dhermes]

@tseaver I upgraded to 0.6.0 but didn't change the branch name, so that we didn't have to open a new PR.

Coverage remained the same at 100.0% when pulling ca4888f on dhermes:cut-release-0.5.1 into 9491053 on GoogleCloudPlatform:master.

I think I would normalize the changelog into imperative mode. E.g.:

General

• Update required version of protobuf to 3.0.0-alpha-1.
• Add from_service_account_json, from_service_account_p12 and from_environment factories to Connection base class, allowing creation of a connection without first creating a set of credentials.

Datastore

• Fix serious bug where the transaction ID was not passed along to transactions, effectively making a transaction act as a batch.
• Add appropriate scope to un-scoped credentials passed to connection constructor.
• Enable connection as an optional argument to all methods and functions which use a connection.
• Require exclude_from_indexes to be a tuple or list in Entity constructor.
• Require projection, order and group_by to be a tuple or list in Query constructor.
• Re-purpose datastore.get to take a single key; move previous functionality to datastore.get_multi. Similar
  changes were made for

datastore.put --> datastore.put_multi

and

datastore.delete --> datastore.delete_multi

Storage

• Add support for "futures", to allow GET/PATCH to work correctly in a batch.
• Remove default chunk size in upload/download.
• Add lazily-loaded default connection and project.
• Remove connection property from Blob/ACL/Bucket classes.
• Enable connection as an optional argument to all methods and functions which use a connection.
• Add appropriate scope to un-scoped credentials passed to connection constructor.
• Update public blob URL to use storage.googleapis.com.
• Remove Bucket.__iter__ and Bucket.__contains__.
• Limit Bucket.make_public(recursive=True) to abort if more than 256 objects are in the bucket. This is similar to what is done in Bucket.delete(force=True).

Pub/Sub

• Add an option to auto-add a timestamp to published, messages, allowing them to be sorted / logged.
• Add appropriate scope to un-scoped credentials passed to connection constructor.
• Enable connection as an optional argument to all methods and functions which use a connection.
• Fix a bug in Subscription.pull for cases when receivedMessages is not returned.

[dhermes]

Cool. Are we all good to merge then?

FWIW I didn't include "Update required version of protobuf to 3.0.0-alpha-1." because that isn't a feature to users. But am happy to include if you think it is important.

[tseaver]

LGTM. I figured we should expose the dependency pin because it might affect how existing users upgrade (or even whether they could).
