Claude docs changes for June 14th, 2026 [diff]

Executive Summary

New enforceAvailableModels setting (v2.1.175+) allows administrators to constrain the Default model option to the availableModels allowlist, closing the bypass where users could always pick "Default" regardless of model restrictions
Changed merge behavior: when availableModels is set in managed or policy settings, it now replaces (not merges with) lower-precedence entries, enabling strict enterprise allowlists
Blocked --model flag now shows a warning naming both the requested and substituted models, instead of silently ignoring the flag

None today.

Clarified that after configuring managed settings, developers should check the Status tab's Setting sources line in /status to verify enterprise managed settings are active. [line 97] [Source]

Removed the marketing banner ("Deploying Claude Code across your organization?") with links to pricing and sales contact from the top of the page.

A blocked --model flag or ANTHROPIC_MODEL value now shows a warning at startup naming both the requested and substituted models, instead of being silently ignored. [line 100] [Source]
New enforceAvailableModels setting: when true alongside a non-empty availableModels list in managed or policy settings, the Default model option is also constrained to the allowlist rather than resolving to the tier default. Requires v2.1.175+. [lines 110-112] [Source]
Updated guidance for fully controlling the model experience now includes enforceAvailableModels as a required component alongside availableModels, model, and the ANTHROPIC_DEFAULT_* env vars. [lines 115-145] [Source]
Changed merge behavior: when availableModels is set in managed or policy settings, the managed/policy value now replaces the merged result from user/project/local settings entirely. Prior to v2.1.175, the managed list was merged with lower-precedence entries. [lines 148-150] [Source]
Added behavior note for opusplan: when availableModels excludes Opus, opusplan stays on Sonnet in plan mode instead of switching; similarly if Sonnet is excluded, the implicit Haiku-to-Sonnet plan-mode upgrade is skipped. [line 174] [Source]

Added availableModels and enforceAvailableModels to the security-enforcement fields table: invalid availableModels entries fall back to an empty allowlist (only Default available), and invalid enforceAvailableModels is treated as true. Both apply in v2.1.175+. [lines 155-156] [Source]
Updated availableModels setting description to remove the previous note that it "does not affect the Default option" (now controlled via enforceAvailableModels). [line 194] [Source]
New enforceAvailableModels setting entry added to the settings reference table. Requires v2.1.175+. [line 219] [Source]
Clarified array merge behavior: availableModels is now documented as a second exception (alongside fallbackModel) where a managed/policy value replaces lower-precedence entries instead of merging. [line 547] [Source]
Improved /status documentation: restructured into a bulleted list explaining what each layer's presence or absence means, with clearer separation between the Status tab and Config tab purposes. [lines 554-561] [Source]

No significant changes today. (Only obfuscated email URL updates in adaptive-thinking, extended-thinking, and files.)
