Release Notes

Use this page to track SDK version changes, breaking changes, and newly added capabilities.

LLM guidance

Use this page when version-specific behavior matters. Check release notes before generating code that depends on newly added methods, changed payload shapes, changed WebSocket behavior, or price-format assumptions.

When To Use This Page

Use this page when you need to:

• confirm whether a feature exists in the SDK version being used
• check whether a workflow changed between releases
• review breaking changes before upgrading
• verify pricing, authentication, or WebSocket behavior by version

Majorly Updated Sections

This Python SDK V2 section is retained for older SDK integrations and V2 payload reference. For SDK 0.5.0 integrations, use the current Python SDK documentation.

• Authentication
• initialization and environment guidance
• Place Order
• single-order payload examples and current trading flow
• Place Multi Order
• multi-order examples aligned to the current behavior
• Place Strategy Order
• major clarification around strategy quantity, base executable quantity, and unitQty
• Modify Order

• Modify Strategy Order

• Get Order Margin

• Realtime Order Updates
• websocket callback usage clarified for current SDK behavior
• Python SDK V3
• use this track for SDK 0.5.0 and the current V3 trading payload flow

Important Rules

Important Rules

• Release notes are version-specific. Always match the documented behavior to the installed SDK version.
• Do not assume older projects use the latest request or response shape.
• Price-format changes matter operationally. In newer SDK versions, prices and many monetary fields are represented as integer paise.
• Check release notes before relying on newly added realtime streams, portfolio response versions, or trading request shapes.
• SDK 0.5.0 uses the current V3 trading payload flow.
• Use this Python SDK V2 section only for older SDK integrations and V2 payload behavior.
