1.5.0

What's Changed

Added

Models API

• Add maxInputTokens and maxTokens properties to RetrieveResponse (and every item returned by ListResponse)
• Add typed capabilities tree on model responses: batch, citations, codeExecution, imageInput, pdfInput, structuredOutputs, thinking (with types.adaptive and types.enabled), and effort (with low, medium, high, max levels)
• Add capabilities.contextManagement as a map keyed by the raw API strategy name (clear_thinking_20251015, clear_tool_uses_20250919, compact_20260112, and any future version), so new strategies Anthropic ships are captured automatically without a package update

Messages API

• Add stop_details on CreateResponse with type, category, and explanation — populated when stop_reason is 'refusal'
• Add caller on tool_use and server_tool_use content blocks (type and tool_id) so direct model calls can be distinguished from calls made inside a code execution sandbox
• Add container_upload content block support with file_id
• Add inferenceGeo to CreateResponseUsage and CreateStreamedResponseUsage, surfacing which region handled the request ('us', 'eu', or null)
• Document the new pause_turn and refusal stop reasons and the idiom for resuming paused turns

Meta information

• Add priorityInputTokenLimit and priorityOutputTokenLimit on MetaInformation, parsing the six anthropic-priority-* headers into typed properties instead of dropping them into the generic custom bucket

Documentation

• Ship the full documentation site at mozex.dev/docs/anthropic-php/v1 with dedicated pages for every feature: introduction, configuration, messages, tool use, server tools, streaming, thinking, citations, batches, token counting, models, completions, meta information, testing, and error handling
• Every page now links back to the matching Anthropic reference on platform.claude.com/docs/

Improved

• tool_use / server_tool_use toArray() output now includes the caller object when present, so response round-trips stay lossless
• MetaInformation rate-limit headers (including the new priority tier) round-trip cleanly through toArray()
