v3.0.1 Release Notes
Highlights
Stabilized the v3 package line after the modernization release.
Composer package remains sudiptpa/omnipay-esewa.
Public SDK shape is now clearly centered around:
Sujip\Esewa
Omnipay\Esewa
Improved model-first design across checkout, callback verification, and transaction status flows.
Added typed value objects for:
amount
transaction UUID
product code
reference ID
Added fromArray() / toArray() support across core request and result models.
Strengthened production safety:
callback signature verification
anti-fraud expectation matching
replay protection with persistent stores
retry policy abstraction
clock abstraction for deterministic replay/expiry logic
Zero-dependency runtime core with built-in CurlTransport.
Optional PSR-18 transport support retained.
Optional Omnipay bridge added for Omnipay-style integrations.
Replay protection now supports:
in-memory store for tests
filesystem store
PDO-backed store
Documentation refreshed:
README
user guide
migration guide
architecture guide
CI and package metadata aligned with current support policy.
Important Changes Since v3.0.0
Public branding and examples now consistently reflect eSewa PHP SDK.
Minimum supported PHP version is now 8.2.
PHP support is now 8.2 to 8.5.
CI matrix now targets the supported versions only.
Breaking Changes
Minimum PHP version changed from 8.1 to 8.2.
The preferred framework-agnostic entry point is now:
Sujip\Esewa\Esewa::make(...)
Integrations relying on undocumented v3.0.0 transitional naming should move to the final public namespaces.
Upgrade Guide
Update package:
composer require sudiptpa/omnipay-esewa:^3.0
Use the framework-agnostic entry point:
Sujip\Esewa\Esewa::make(...)
Use typed request models for the main flows:
CheckoutRequest
CallbackPayload
VerificationExpectation
TransactionStatusRequest
For callback handling:
verify on the backend
branch on verification state
do not trust redirect-only success
For production:
use FilesystemIdempotencyStore or PdoIdempotencyStore
keep replay protection enabled
keep anti-fraud expectation checks enabled
use status reconciliation when callback state is uncertain
For Omnipay-style integrations:
use Omnipay\Esewa\SecureGateway
Notes
This release is a stabilization release for the v3 line.
It focuses on API cleanup, PHP compatibility alignment, CI reliability, stronger typing, and production hardening.
You can’t perform that action at this time.
