# Cloud Platform Updates

> New releases and improvements of the Cloud Platform.

<Update label="May 21, 2026" tags={["New Release", "Improvement"]}>
  ## Hellgate Web SDK (v3.10.0)

  ### Cardholder-Aware Token Lifecycles

  Align token retention with what your cardholder actually agreed to. A new optional
  `ephemeral?: boolean` argument on `process()` and `tokenize()` defaults to `true`,
  meaning the cardholder is *not* remembered. Flip it to `false` only on explicit
  consent — for example, when a customer ticks a "Save my card" box at checkout.

  ### Smarter Scheme Validation

  Allowed card schemes configured on the session now flow through to client-side
  card number validation. Cardholders see scheme errors immediately, before the
  request ever leaves the browser.

  ### Improvements and bugfixes

  * Empty `card_schemes` configuration now correctly allows all schemes.
  * Separate expiry month/year inputs now treat `'1'` as a valid month and
    properly reject past-expiry dates.
  * Demo: a new "Save my card" checkbox in the tokenization demo wires straight
    into the new ephemeral toggle so you can try it end-to-end.
</Update>

</Update>

<Update label="June 5, 2025" tags={["New Release", "Improvement"]}>
  ## Hellgate Android SDK (v1.1.0)

  The Android SDK now encrypts the full payload — including any additional data —
  into a single JWE and returns it to your app, instead of calling the tokenization
  backend directly. This simplifies your integration and keeps sensitive data
  encrypted end to end.

  ### Improvements and bugfixes

  * Additional cardholder data is now encrypted as part of the JWE token.
  * Hellgate error responses now surface with clearer, more actionable detail.
  * Removed support for tokenizing through an external token provider.
  * Updated environment URLs.
</Update>

<Update label="May 7, 2025" tags={["Improvement"]}>
  ## Hellgate Web SDK (v3.7.0)

  Add 'onSessionComplete' handler to Hellgate® client with result data.
</Update>

<Update label="April 8, 2025" tags={["Improvement"]}>
  ## Hellgate Web SDK (v3.5.3)

  Improved the SDK with small but important fixes:

  * Fix masked input behaviour
  * Reject cardHandler.process() promise if BE responds 40x / 50x status code
  * Await cardHandler.process() throws exceptions if card date is not complete or invalid
  * Show full CVC code up to 4 digits
  * Card scheme validation by default
  * UnionPay card number input

  Added some new features:

  * Encrypt additional\_data payload on tokenize
  * User can refresh CVC2 code of a token from WebSDK
</Update>

  ## Hellgate iOS SDK (v1.0.0)

  The first release of the Hellgate® iOS SDK brings cardholder data tokenization
  to native iOS apps. Collect and tokenize the card number, CVC, and expiration
  date, and attach additional fields to capture cardholder information — so raw
  card data never touches your own backend.
</Update>

  The first release of the Hellgate® Android SDK brings cardholder data
