Description

The a2a-python SDK recently released v1.0.0 which upgrades from the 0.3 protocol spec to the 1.0 protocol spec. This introduces breaking changes to module paths and APIs that our A2A templates depend on (e.g., a2a.server.agent_execution, a2a.types, a2a.utils).

Since our templates specify a2a-sdk >= 0.2.0 with no upper bound, pip install now resolves to 1.0.x, breaking all agentcore create --protocol A2A projects.

This PR adds < 1.0.0 upper bound to all three A2A template pyproject.toml files so pip resolves to 0.3.26 (latest compatible version).

fix: pin a2a-sdk below 1.0 to prevent breaking changes
42487c0
The a2a-python SDK recently released 1.0 with breaking protocol changes
(0.3 spec -> 1.0 spec). Our A2A templates use 0.3-era APIs (a2a.server,
a2a.types, a2a.utils) which are incompatible with the 1.0 release.
Add an upper bound (< 1.0.0) to all three A2A template pyproject.toml
files so pip resolves to 0.3.26 (latest compatible) instead of 1.0.x.

Reviewed the diff — this looks good to merge.

Verified:

  • Templates import from a2a.server.agent_execution, a2a.server.events, a2a.server.tasks, a2a.types, and a2a.utils, which are the 0.3-era paths that the PR description says broke in 1.0, so the upper bound is warranted.
  • The < 1.0.0 constraint is applied to all three A2A templates (googleadk, langchain_langgraph, strands), the [all] extra on strands is preserved, and the snapshot is updated consistently.
  • Confirmed against PyPI that the highest stable release under 1.0 is 0.3.26, so pip will resolve to a working version.
  • No other references to a2a-sdk elsewhere in src/ that would need a matching pin.

No blocking issues.

Description
The a2a-python SDK recently released v1.0.0 which upgrades from the 0.3 protocol spec to the 1.0 protocol spec. This introduces breaking changes to module paths and APIs that our A2A templates depend on (e.g., a2a.server.agent_execution, a2a.types, a2a.utils).
Since our templates specify a2a-sdk >= 0.2.0 with no upper bound, pip install now resolves to 1.0.x, breaking all agentcore create --protocol A2A projects.
This PR adds < 1.0.0 upper bound to all three A2A template pyproject.toml files so pip resolves to 0.3.26 (latest compatible version).

fix: pin a2a-sdk below 1.0 to prevent breaking changes
42487c0
The a2a-python SDK recently released 1.0 with breaking protocol changes
(0.3 spec -> 1.0 spec). Our A2A templates use 0.3-era APIs (a2a.server,
a2a.types, a2a.utils) which are incompatible with the 1.0 release.
Add an upper bound (< 1.0.0) to all three A2A template pyproject.toml
files so pip resolves to 0.3.26 (latest compatible) instead of 1.0.x.

Reviewed the diff — this looks good to merge.
Verified:
  • Templates import from a2a.server.agent_execution, a2a.server.events, a2a.server.tasks, a2a.types, and a2a.utils, which are the 0.3-era paths that the PR description says broke in 1.0, so the upper bound is warranted.
  • The < 1.0.0 constraint is applied to all three A2A templates (googleadk, langchain_langgraph, strands), the [all] extra on strands is preserved, and the snapshot is updated consistently.
  • Confirmed against PyPI that the highest stable release under 1.0 is 0.3.26, so pip will resolve to a working version.
  • No other references to a2a-sdk elsewhere in src/ that would need a matching pin.
No blocking issues.

Description
The a2a-python SDK recently released v1.0.0 which upgrades from the 0.3 protocol spec to the 1.0 protocol spec. This introduces breaking changes to module paths and APIs that our A2A templates depend on (e.g., a2a.server.agent_execution, a2a.types, a2a.utils).
Since our templates specify a2a-sdk >= 0.2.0 with no upper bound, pip install now resolves to 1.0.x, breaking all agentcore create --protocol A2A projects.
This PR adds < 1.0.0 upper bound to all three A2A template pyproject.toml files so pip resolves to 0.3.26 (latest compatible version).

The a2a-python SDK recently released 1.0 with breaking protocol changes
(0.3 spec -> 1.0 spec). Our A2A templates use 0.3-era APIs (a2a.server,
a2a.types, a2a.utils) which are incompatible with the 1.0 release.
Add an upper bound (< 1.0.0) to all three A2A template pyproject.toml
files so pip resolves to 0.3.26 (latest compatible) instead of 1.0.x.

Reviewed the diff — this looks good to merge.
Verified:
  • Templates import from a2a.server.agent_execution, a2a.server.events, a2a.server.tasks, a2a.types, and a2a.utils, which are the 0.3-era paths that the PR description says broke in 1.0, so the upper bound is warranted.
  • The < 1.0.0 constraint is applied to all three A2A templates (googleadk, langchain_langgraph, strands), the [all] extra on strands is preserved, and the snapshot is updated consistently.
  • Confirmed against PyPI that the highest stable release under 1.0 is 0.3.26, so pip will resolve to a working version.
  • No other references to a2a-sdk elsewhere in src/ that would need a matching pin.
No blocking issues.
