# Adapty January update

Things you've been waiting since December

## A/B price testing for in-app purchases

Finally, it's here.

**Core changes**

1. [**Products are now editable**](https://adapty.io/docs/product). If you want to change or delete Adapty product, just do it.
2. [**Paywall is a dedicated entity now**](https://adapty.io/docs/paywalls). Configure paywall with in-app purchases and subscriptions (Adapty products) without A/B tests. Change products, order, custom JSON, and more. Paywalls have dedicated metrics as well.
3. [**Custom JSON size increased to 4k chars.**](https://adapty.io/docs/customize-paywall-with-remote-config) Feel free to reach us if you need more storage.
4. [**A/B price testing metrics are available for targeted paywalls.**](https://adapty.io/docs/results-and-metrics)
5. **Paywalls and A/B tests are vice-a-versa convertible to each other.** To run price testing you don't need to make a new app release.

## Server API boost

Now it's even easier to integrate web subscriptions and purchases with Adapty. Server API is getting more muscles. Use it for integration with Stripe, ChargeBee, and *any other* payment provider. We even prepared a [handful of snippets and docs](https://adapty.io/docs/getting-started-with-server-side-api) for you.

1. **Share purchase price and currency in a transaction.**
2. **Cancel users subscription and make a refund**.

Adapty Server API is useful for every mobile and web payment provider! Use it to sync subscribers and get actual subscription status.

## Mobile SDK improvements

Adapty supports all SDKs: [iOS](https://github.com/adaptyteam/AdaptySDK-iOS), [Android](https://github.com/adaptyteam/AdaptySDK-Android), [React Native](https://github.com/adaptyteam/AdaptySDK-React-Native), [Flutter](https://github.com/adaptyteam/AdaptySDK-Flutter) and [Unity](https://github.com/adaptyteam/AdaptySDK-Unity). Each day we make them better and more reliable.

1. iOS&Android: speed improvements and SDK design changes. Read more [here](https://adapty.io/docs/fetch-paywalls-and-products#fetch-products).
2. Android: increased stability for consumable (one-time) purchases.
3. Flutter: [manual visitor logging for paywalls](https://adapty.io/docs/fetch-paywalls-and-products#fetch-products). Used for price testing metrics.
