Versioning

Prism follows Semantic Versioning 2.0.0. A minor version upgrade or a patch will never break your existing integration.

MAJOR.MINOR.PATCH
  1    .2    .3

Version Number Meanings

Position	When It Changes	What It Means for You
PATCH (1.2.3 → 1.2.4)	Bug fixes, security patches	Update automatically. Zero code changes required.
MINOR (1.2.x → 1.3.x)	New features, new connectors	Add capabilities without touching existing code.
MAJOR (1.x.x → 2.x.x)	Breaking API changes	You must update your code. Migration guide provided.

Pinning for Automatic Bug Fixes

It is strongly recommended You want security patches and critical fixes without manual updates. Pin your dependency to accept patch increments automatically.

Node.js (package.json)

{
  "dependencies": {
    "@juspay/connector-service-node": "1.2.*"
  }
}

This accepts: 1.2.0, 1.2.1, 1.2.4, 1.2.15
This rejects: 1.3.0, 2.0.0

Python (requirements.txt)

juspay-connector-service==1.2.*

Or in pyproject.toml:

[tool.poetry.dependencies]
juspay-connector-service = "1.2.*"

Java (Maven)

<dependency>
    <groupId>com.juspay</groupId>
    <artifactId>connector-service</artifactId>
    <version>[1.2.0,1.3.0)</version>
</dependency>

The [1.2.0,1.3.0) syntax means: 1.2.0 inclusive, 1.3.0 exclusive.

Rust (Cargo.toml)

[dependencies]
connector-service = "1.2"

Cargo treats 1.2 as ^1.2.0, which accepts 1.2.0 through 1.2.999 but not 1.3.0.

What You Get Automatically

When you pin to 1.2.*, your build system pulls these automatically:

Patch releases (automatic):

• Security fixes for connector authentication
• Bug fixes for specific PSP error parsing
• Performance improvements
• Documentation corrections

Minor releases (manual opt-in):

• New connector support (e.g., "Added Peach Payments")
• New payment methods (e.g., "Added UPI")
• New SDK features (e.g., "Added async streaming")
• Deprecation warnings for old APIs

Major releases (manual migration):

• Breaking changes to core types
• Removal of deprecated methods
• Fundamental architecture changes

The Risk of Pinning Too Tightly

{
  "dependencies": {
    "@juspay/connector-service-node": "1.2.3"
  }
}

This pins exactly to 1.2.3. You miss:

• 1.2.4 — Fix for Stripe webhook signature verification
• 1.2.5 — Security patch for Adyen credential handling
• 1.2.6 — Critical fix for refund idempotency keys

Your code works today. It breaks tomorrow when Stripe rotates certificates and you lack the fix.

The Risk of Pinning Too Loosely

{
  "dependencies": {
    "@juspay/connector-service-node": "*"
  }
}

This accepts any version, including 2.0.0 with breaking changes. Your CI passes today. Production fails tomorrow when a new major version introduces API changes.

Recommended Strategy

Pin to minor version for active development:

1.2.*

This gives you:

• Automatic security patches
• Automatic bug fixes
• No surprise breaking changes
• Control over when new features arrive

Update minor versions intentionally when you need new connectors or features. Read the changelog. Run your integration tests. Then bump the pin.

Version Compatibility Matrix

Prism maintains compatibility across SDK languages for the same minor version:

Prism Version	Node.js SDK	Python SDK	Java SDK	Rust SDK
1.2.x	1.2.x	1.2.x	1.2.x	1.2.x
1.3.x	1.3.x	1.3.x	1.3.x	1.3.x

All SDKs for version 1.2.x speak the same protocol, support the same connectors, and handle the same error codes. Mixing SDK versions (Node.js at 1.2.5, Python at 1.3.0) works but may produce different behaviors for newer features.

Checking Your Current Version

# Node.js
npm list @juspay/connector-service-node

# Python
pip show juspay-connector-service

# Java
mvn dependency:tree | grep connector-service

# Rust
cargo tree | grep connector-service

Deprecation Policy

Prism maintains deprecated APIs for one full major version. When 2.0.0 releases:

• APIs deprecated in 1.x are removed
• Migration guides are published
• Automated codemods are provided where possible

You have the entire 1.x lifecycle to update your code before breaking changes arrive.

Pin to MAJOR.MINOR.*. Get fixes automatically. Control features manually. Sleep soundly.
