Release 4.10 is live!

brainCloud 4.10 adds new Security Options, an upgraded Cloud Code Engine, new Advanced Authentication calls, and more.

Release Highlights

TLS Security Enforcement

We are hardening the security of our Public BaaS environment to enforce TLS 1.2 for all APIs.

To facilitate a manageable transition – we have added an additional API endpoint to our public BaaS. So our public BaaS now supports:

  • api.braincloudservers.com – our new API endpoint that supports TLS 1.2 only… (we will further upgrade it to support TLS 1.3 as well when AWS supports it)
  • sharedprod.braincloudservers.com – this is our legacy endpoint that currently supports TLS 1.0, 1.1 and 1.2. This URL will be re-targeted to the same endpoint as api.braincloudservers.com starting June 7, 2022 ← approximately 90 days from now.

Note that other than the version of TLS enforced, these two endpoints function exactly the same. Your apps and players will not see any difference!

Our 4.10 client libraries have all been updated to use api.braincloudservers.com as the new default serverUrl for API calls. If you are using an older library, you can simply specify "https://api.braincloudservers.com/dispatcherv2" for the serverUrl parameter of the wrapper Initialize() call – see API Reference.

Once your app is calling the new endpoint, you can then go to the new Design | Core App Info | Security page, and set the minimum API TLS to 1.2. Careful though – this will mean that any calls to the older API endpoint (sharedprod.braincloudservers.com) will be rejected! ← because brainCloud cannot otherwise ensure that they were at least TLS 1.2.

Note that our RTT websocket endpoint is already enforcing a minimum TLS of 1.2. The raw TCP version of RTT however, which is used only for clients that cannot support WebSockets, is not encrypted. Setting Minimum RTT TLS Version to 1.2 thus disables the raw TCP connection option for your app. 

Note that both Unity and Unreal clients use the encrypted websocket implementation by default – so removing this option does not affect 99% of apps.

Migration options

In summary, brainCloud 4.10 allows developers to bump up the minimum level of TLS for client APIs. Developers have two options on how they would like to migrate:

  1. Do nothing – If you do nothing, your app will automatically be upgraded to TLS 1.2 starting on June 7, 2022 when sharedprod.braincloudservers.com merges with api.braincloudservers.com and begins enforcing a minimum TLS of 1.2.
  2. Migrate early– For developers wanting to improve their app security now, the new API and security settings provide the means to de-risk and accelerate the migration – which is definitely convenient for devs maybe going through Facebook’s Privacy Checklists for example. The recommended approach is:
    1. Reconfigure your app to talk to api.braincloudservers.com – either by updating to the 4.10 libs – or overriding the serverUrl parameter in wrapper Initialize().
    2. Confirm that your app works just fine
    3. Release the updated build of your app – so that you can get the majority of your player base migrated over
    4. Set the minimum client version of your app to force upgrades for any stragglers.
    5. Adjust the TLS settings of your app to require TLS 1.2. You are done!

Cloud Code Engine Upgrade

We have upgraded the Mozilla Rhino Engine from 1.7.13 → 1.7.14.

This brings with it support for the following Javascript features:

  • Template Literals!
  • Promise Support (Requires app to be set to ES6)
  • Error stack traces!

And more! 

For the full details, see the Rhino 1.7.14 Release Notes.

Advanced Authentication

Developers of certain categories of apps have long asked for the ability to register a new user, and set default attributes, etc. for that user during the initial Authentication call. This is not possible with the existing Authentication calls – so we have added a new set of calls to satisfy this use case. 

The new AuthenticateAdvanced() call allows the developer to include an extraJson payload with the authentication call, which can then be picked up by pre- or post- API hooks for additional processing as the account is created.

Note that for simplicity, all authentication types are handled by the single AuthenticateAdvanced() call – similar to how the API Explorer works… Corresponding Merge() and Detach() calls have been added to the Identity service as well.

Group and Group Entity Enhancements

We have done a full review of our Group and Group Entity code, and found some areas that warranted improvements. The following changes/fixes have been made:

  • Improved handling of ACL permissions – In particular, some GroupEntity operations were being gated via the Group ACL instead of the Group Entity ACL! Note that there is a compatibility flag to preserve the old behaviour.
  • Improved concurrency handling – we have improved the locking of several key methods – including managing group membership.
  • Added missing Group “Sys” API call – Added Sys implementation for SysRemoveGroupMember()
  • New SysGetRandomGroupsMatching() call – this is a more useful implementation of the GetRandomGroupsMatching() call – which is hampered by ACL permissions not allowing the API to return full details of groups that the user is not a member of. We would recommend that in most use cases, it is more correct to use SysGetRandomGroupsMatching() than GetRandomGroupsMatching() – though like all Sys calls, SysGetRandomGroupsMatching() is not available directly via the client API – so you’ll need to call it via a cloud code script.
  • Updated ReadGroupMembers() and SysReadGroupMembers() calls to return a user’s summaryFriendData

Additional Features

  • Unreal Relay communications – we have completely re-written Unreal relay communications for this release. In addition, we have created an Unreal-based Relay Tester app to demonstrate the usage of the relay server APIs.
  • Improved credential checks – we have added improved versions of getProfileInfoForCredential() and getProfileInfoForExternalAuth() that don’t unnecessarily log an error if the credential isn’t found. This is handy for use cases where a credential not being found is normal – and isn’t worth flagging as an error in the logs. The new methods are:  getProfileInfoForCredentialIfExists() and getProfileInfoForExternalAuthIfExists()
  • Faster file deployments – brainCloud will now copy multiple files in parallel during app deployments. This should have a noticeable reduction in deployment times for some apps.
  • Ultra authentication – brainCloud APIs now support user authentication for apps on the Ultra.io platform. 
  • Unity Chat – a new Unity Chat example app has been created. You can find the source for it here
  • Unreal Relay Test – a new Unreal Relay Test example app has been created. You can find the source for it here

Plus 4.9.5 Patch items

The following additions were technically included in 4.9.5 patches – but are described here for completeness:

  • Illegal file types – Developers are no longer allowed to upload certain file types. Currently disallowed extensions are: html,htm,jsp,php,bat,cmd,exe,js,pif,ps1,scr,vb,vbe,vbs
  • SysUpdateEntityFieldSharded() call – added new SysUpdateEntityFieldSharded() call for use with sharded Custom Entity Collections. This is because the existing SysUpdateEntityField() will not work for owned custom entities once sharded.
  • Improved Room and Relay Servers – improved handling for long-lived lobbies with join-in-progress servers.
  • Improved RTT connection handling – improved handling of RTT connection disconnects. 

Portal Changes

We have made the following portal changes:

Design 

  • Core App Info | Advanced Settings
    • Added a new compatibility flag to preserve the old (and incorrect) GroupEntity / Group ACL behaviour. By default this flag is enabled for existing apps – but it is recommended that devs review their apps and clear this flag when possible.
  • Core App Info | Security
    • This new screen allows devs to customize the security settings of their apps. For more information, see the TLS Security Enhancements section above.

Monitoring

  • Global Monitoring | Custom Entities
    • Improved performance when showing all entities for a custom entity collection with tons of entities.
  • Global Monitoring | Recent Errors
    • Fixed an issue that would cause logs to show the wrong relative date in certain timezone situations.

Reports

  • Reporting | Analytics
    • The Dormant Users statistics table has been updated.
  • Reporting | API Usage
    • Fixed an issue displaying usage stats for games with > 2.1 Billion game sessions.

General

  • Unlocking apps – Unlocking a live app (via the Live Lock Banner) now requires the developer to type the name of the app, not the developer’s password. This is more in tune with the original design intent for the banner (which was to ensure the developer is aware of which particular version of their app (production, development, etc.) is being changed) – and interacts better with the PortalSSO integrations of private licensee’s brainCloud instances.

API Changes

The following changes/additions have affected the brainCloud API:

  • Authentication
    • New AuthenticateAdvanced() call that allows extraJson payload to be included with player authentication / registration
    • New AuthenticateUltra() call allows apps to authenticate with the Ultra.io platform
  • Custom Entity
    • New methods UpdateEntityFieldsSharded() and SysUpdateEntityFieldsSharded() are sharding-safe implementations of the older UpdateEntityFields() and SysUpdateEntityFields() methods. The non-sharded versions of these methods are now recommended only for custom entity collections that you know you will never want to shard in the future (i.e. small, probably static collections).
  • Friend
    • The new getProfileInfoForCredentialIfExists() and getProfileInfoForExternalAuthIfExists() methods behave just like getProfileInfoForCredential() and getProfileInfoForExternalAuth() respectively – except that they don’t log errors if the credentials don’t exist. Handy and cleaner for many use cases.
  • Group
    • New SysGetRandomGroupsMatching() call is a more convenient version of GetRandomGroupsMatching() – which eliminates the need to give read-only access to “other” users.
    • Added new S2S + cloud code only method: SysRemoveGroupMember()
    • Updated ReadGroupMembers() and SysReadGroupMembers() to return a user’s summaryFriendData
    • Improved concurrency handling
    • Improved handling of ACL permissions; behaviour changes are gated by a new compatibility flag.
  • Group Entity
    • Improved concurrency handling
    • Improved handling of ACL permissions; behaviour changes are gated by a new compatibility flag..
  • Identity
    • New cloud code only GetIdentityData() call allows apps to retrieve additional information regarding a specific player identity. Currently only supported for the new Ultra authentication.
    • New Advanced identity methods: AttachAdvancedIdentity(), DetachAdvancedIdentity(), MergeAdvancedIdentity()
    • New Ultra identity methods: AttachUltraIdentity(), DetachUltraIdentity(), MergeUltraIdentity()
  • RTT
    • EnableRTT() now fails if the app’s plan does not support RTT. Note that this is a server-side check, and is not limited to the 4.10 client library.

We have attached warnings in the API docs to the following methods:

  • Custom Entity
    • UpdateEntityFields() and SysUpdateEntityFields() – These methods are not sharding safe – and thus are not recommended for custom entities that you may want to shard for greater performance and scalability in the future. Consider using UpdateEntityFieldsSharded() and SysUpdateEntityFieldsSharded() instead.
