# IMPORTANT: LEGACY V0 CODE - Deprecated since version 1.0.0, scheduled for removal April 1, 2026
|
|
# This file is part of the legacy (V0) implementation of OpenHands and will be removed soon as we complete the migration to V1.
|
|
# OpenHands V1 uses the Software Agent SDK for the agentic core and runs a new application server. Please refer to:
|
|
# - V1 agentic core (SDK): https://github.com/OpenHands/software-agent-sdk
|
|
# - V1 application server (in this repo): openhands/app_server/
|
|
# Unless you are working on deprecation, please avoid extending this legacy file and consult the V1 codepaths above.
|
|
# Tag: Legacy-V0
|
|
# This module belongs to the old V0 web server. The V1 application server lives under openhands/app_server/.
