API

Released new API version v1beta15

v1beta14 is now deprecated and customers should switch to v1beta15 . v1beta14 will remain available until August 15, 2013 and v1beta13 will be discontinued on May 31, 2013 . For more information on how t transition to v1beta15, see our transition guide .

Changes in v1beta15 include:

Introduced new region scope and regional resources .
- Added new regional resource URIs to access regional resources, in the form:
```
    https://www.googleapis.com/compute/v1beta15/project/<project-id>/regions/<region-name>/<resource-type>/<resource-name>
```
  For example, to access regional reserved IPs , use the following regional URI:
```
    http://www.googleapis.com/compute/v1beta15/project/example.com:myproject/regions/example-region/addresses
```
- Updated reserved IP addresses to a regional resource.
  
  External static IPs are now referred to as reserved IP addresses and are no longer a global resource. Reserved IPs are now a regional resource that can be managed through the Addresses collection .
  
  You can also provision, promote, and release external IP addresses through the Addresses collection, without having to manually request one. For more information, see the Reserved Addresses documentation .
Converted machine type resources to per-zone resources.

To use a machine type, you must now specify the zone in which that machine type lives:
```
http://www.googleapis.com/compute/v1beta15/project/example.com:myproject/zone/example-zone/machineTypes/machineTypeName
```
Changed method of creating Snapshot resources to use a custom verb on the Disk resource.

To create a Snapshot resource, you must now make a request to the following URI:

https://www.googleapis.com/compute/v1beta15/projects/ /zones/ /disks/ /createSnapshot

Snapshots are still accessible by making requests to the Snapshot collection.
Removed ability to assign an internal IP address.

The internalIp field on a virtual machine instance is now read-only and you can no longer manually assign internal IPs to your instances. Google Compute Engine will assign internal IPs automatically.
Added a number of new features.
- Added new Routes collection that lets you set up and manage a virtual machine's routing table.
- Added ability to reserve and release static IPs , and to promote ephemeral IPs to static IPs.
- Added the ability to request aggregate lists for per-zone and per-region resources. You can request aggregate lists for the following resources:
  - Instance resources
  - Disk resources
  - Address resources
  - Machine type resources
For example, you can list instances across all zones by making a request to the following URI:
```
https://www.googleapis.com/compute/v1beta15/project/example.com:myproject/aggregated/instances
```

Machine types

Introduced new shared-core machine types .

Shared-core machine types are more cost-effective for running applications that don't require a lot of resources. New available machine types are g1-small and f1-micro .
Updated maximum total persistent disk size that can be attached to a machine type.

Standard, high memory, and high CPU machine types now have an updated maximum total disk size of 10 TB . See machine types for more information.

Billing

Updated billing model for instances.

Google Compute Engine has updated our billing model so that instances are billed based on per-minute usage. All instances that run for 10 minutes or less will be charged for 10 minutes of usage. After the first 10 minutes, usage is charged on a per-minute basis.

Images

Added new images and kernels v20130515 .
Removed Google-specific repositories from images. The only packaged repositories configured in images are now the Debian archive. Google Compute Engine still installs Google-specific packages at build time but removed Google- specific repositories for various reasons.
Removed default installation of the apiclient library.
Changed log location of startup script output to /var/log/startupscript.log . Also, added startup script log output to the instance's serial port console so you can also run gcutil getserialportoutput to retrieve startup script log information.
Improved instance creation and deletion time for Debian.
Fixed issue preventing startup script specified in metadata to be downloaded from Google Cloud Storage.
Removed dist-upgrade from starting on instance boot.
Removed google_storage_download script.

gcutil

Release 1.8.0

New features
- Added support for v1beta15 Google Compute Engine API. (addresses, regions, per-zone machine types, aggregated lists).
- Added gcutil config command, an alias for gcutil auth .
- When prompting the user to select an image, gcutil will include standard images (CentOS, Debian).
- With v1beta15 API, gcutil will use aggregated list API call by default. Aggregated list method will aggregate all resources across all scopes in which the resource of that type exist (for example, aggregated list of instances will list instances in all zones).
- Users can specify image from the standard project by specifying image name prefix. For example: gcutil addinstance my-instance --image=debian-7 .
Bug fixes
- When moving instances using gcutil moveinstances , if some of the instances depend on deprecated resources (image, kernel), gcutil will warn before it proceeds with the migration (migration would fail). New flag --replace_deprecated will create instances in the destination zone with dependencies on deprecated resources updated to recommended replacement resources.
Other changes
- List commands will display all resources by default. Number of resources listed may be limited using --max_results flag. --fetch_all_pages flag is now deprecated.
- Improved display of images and kernels list. By default, only newest kernels/images will be displayed when listed or when user is prompted to select an image or kernel. Use --old_images or --old_kernels to list all images or kernels, respectively.
- When listing imges, the standard images (CentOS, Debian) will be listed in addition to images from the specified project. To list images in the specified project only, use --nostandard_images flag.
- When prompting user to select a machine type, gcutil displays machine type description in addition to the name.
- Removed support for v1beta13 Google Compute Engine API.

API

Released new API Version v1beta13

v1beta12 is now deprecated and customers should switch to v1beta13. V1Beta12 will remain available until January 11, 2013 . Changes in v1beta13 include:

Removed hostCpus field from the machineType resource
Changed API nouns and verbs to use camelCase, specifically:
- machine-types is now machineTypes
- add-access-config and delete-access-config is now addAccessConfig and deleteAccessConfig
- set-common-instance-metadata is now setCommonInstanceMetadata
Made setCommonInstanceMetadata an asynchronous operation, returning an operation resource to track completion of the request
Add serial port output API
Fix metadata key validation and prevent duplicate metadata keys
PENDING and RUNNING states of long-running operations now reflect the full lifetime of the request
Delete operations now guarantee that the DONE state is not reached until after the resource has been completely torn down

To update your application code to v1beta13:

Change all URIs from v1beta12 to v1beta13 . For example:

https://www.googleapis.com/compute/v1beta13/disks

Update API nouns and verbs that have a dash to use camelCase (e.g. machineTypes instead of machine-types )
Update your application code to reflect the following changes, if necessary:
- setCommonInstanceMetadata now returns an Operations resource
- New metadata keys must match the regex [a-zA-Z0-9-_]{1,128} and be less than 128 bytes in length. Metadata values cannot be longer than 32768 bytes
  
  Note: If your metadata value exceeds 32768 bytes, consider using a startup script
- Operations can take longer to complete as they now reflect the total time it takes to roll out and confirm the request
- Delete operations only return DONE after the resource has been completely torn down
- Instances have new additional STOPPING state, which means that the instance is currently in process of being stopped

gcutil

Release 1.3.4

New features
- Implemented batch adddisk . It is now possible to add multiple disks with a single call to gcutil adddisk .
- Implemented batch delete operations for additional resources. It is now possible to delete multiple disks, firewalls, images, instances, networks, operations, and snapshots.
- Added a --format flag for the list subcommands. The flag accepts the following values: table , sparse , json , csv , and names . --format=names allows gcutil to be used with Unix tool pipelines:
```
$ gcutil listinstances --format=names | xargs gcutil deleteinstance --force
```
Bug fixes
- Fixed the sorting in list subcommands. Instead of sorting each page individually, gcutil now sorts all results before displaying them to the user.
- Changed --cache_flag_values to not cache flags when the underlying command fails.
Other changes
- Deprecated --project_id in favor of --project . --project_id still works, but will produce a warning.
- Reconfigured the version checking to take place when gcutil exits.
- Improved documentation for firewall commands.
- Changed the headings for list and get subcommands. The new headings use dashes instead of spaces and are in lower-case. This eliminates the need to use quotes with the --sort_by flag and makes the display of the headings more user-friendly.

Google Compute Engine Console

Added serial console output from a VM instance to the instance details page.
Added support for attaching persistent disks in read-only mode as well as read-write mode.
Added new example gcutil commands for adding instances, disks, networks, and firewalls.

Fixed assorted bugs.

September 18th, 2012

gcutil

Release 1.2.0

New features
- Added support for gs:// URLs to the addimage command.

Bug fixes
- Added a check to commands dealing with metadata to warn the user of duplicate metadata keys instead of silently ignoring duplicates.
- Fixed an issue where listoperations would not fetch multiple pages when encountering an operation that contains an error.
Other changes
- Changed the way gcutil is packaged.
- Made some of the flag descriptions and an error messages more informative.
