Anthropic News | Claude Code v2.1.185 API Waiting Experience Improvements and SDK Update
On June 22, 2026, the Clauder Navi editorial team brings you official Anthropic information in news program style. Today, two new releases were confirmed in the GitHub Claude Code repository. Both are minor patches without behavioral changes, but they include UX fixes that directly affect the operational experience of engineers executing long-running tasks.
Today's releases consist of two items: a minor UX patch for Claude Code v2.1.185 and a followup Python SDK release. There are no updates dated June 21 from Anthropic's official news or Engineering Blog, making the GitHub release today's only activity. There are no feature additions, nor any substantial changes to behavior.
The core of v2.1.185 is the change in the message displayed while waiting for an API response, from "No response from API · Retrying in …" to "Waiting for API response · will retry in …". Additionally, the trigger threshold has been extended from 10 seconds to 20 seconds, mitigating the problem where users would interrupt their operations due to false alarm warnings during analysis of large codebases or execution of refactoring.
claude-agent-sdk-python v0.2.106 is a followup bundle release for CLI v2.1.185, and projects that manage the SDK via pip will automatically incorporate the new CLI at the next upgrade. There are no SDK-specific feature changes, and the UX improvements from v2.1.185 can be enjoyed as-is.

【1】Claude Code v2.1.185 — Improving API Waiting Display from "Retrying" to "Waiting"
On June 20, 2026, at 20:59 UTC, Claude Code v2.1.185 was released (Release notes). It's a minor patch, one version ahead from the previous v2.1.183 (June 19).
When a delay occurs in stream response, Claude Code displays a message to inform the user of the situation. The previous message "No response from API · Retrying in …" conveyed a misleading impression of "an error occurred and is being retried." In reality, there are many cases where the API is simply still generating a response, and this appears to have been causing users to judge that things are "stuck" and interrupt their operations.
In v2.1.185, this wording has been changed to "Waiting for API response · will retry in …", a more accurate expression to convey the state of "waiting." Additionally, the threshold before the message is displayed has been extended from 10 seconds to 20 seconds. For task execution on large codebases or long refactoring instructions, it can be inferred that many users felt anxious due to the message appearing frequently with the traditional 10-second threshold. Going forward, since the message will appear only after waiting for 20 seconds, unnecessary operation interruptions during processing will be less likely.
Impact for engineers: ★☆☆ (Low). There is no change in behavior, only an improvement in the display. However, for teams using Claude Code in practice for long-running tasks, this results in substantial experience improvement. Source: https://github.com/anthropics/claude-code/releases/tag/v2.1.185
【2】claude-agent-sdk-python v0.2.106 — CLI v2.1.185 Followup Bundle Release
On the same day (June 20, 2026, at 21:12 UTC), claude-agent-sdk-python v0.2.106 was released (Release notes).
claude-agent-sdk-python is a Python package that bundles and distributes Claude Code CLI. This release is a routine release intended to follow the v2.1.185 bundle mentioned above, and it does not include any new features or bug fixes to the SDK itself. For projects that manage claude-agent-sdk-python via pip, running pip install --upgrade claude-agent-sdk-python will incorporate CLI v2.1.185. For cases where the CLI is managed manually, this SDK update operates independently.
Impact for engineers: ★☆☆ (Low). This is a release that only affects projects managing the CLI bundle through the SDK. Source: https://github.com/anthropics/claude-agent-sdk-python/releases/tag/v0.2.106
Next Steps to Watch
Today's two items are both minor fixes, but looking back at recent Claude Code releases, we can see that patches are being provided at short intervals. v2.1.183 (June 19) included practical safety improvements such as blocking destructive git operations in automatic mode, and v2.1.185 added UX fixes the very next day at a rapid pace. It's clear that the Claude Code team is reflecting user feedback in real time.
