0.1.2 - 2026-06-20

Fixed

Security and transport:

• SSRF: Req no longer auto-follows redirects. Every redirect hop is validated
  against the URL policy, including on streaming paths.
• PII: overlapping detector spans (such as a URL containing an IP) no longer
  crash or garble output. Spans are pruned to stay disjoint.
• IPv4 reserved-range checks no longer over-block public /16 ranges.
• IPv6 fe80::/10 is treated as reserved, so it stays blocked when
  allow_metadata? is on.
• Per-call request options (including :timeout) override client transport
  defaults instead of being shadowed.

Providers:

• Anthropic: beta flags go in the anthropic-beta header, not the body. This
  covers invoke, stream, stream_events, and count_tokens.
• Anthropic: final streaming usage is a proper usage map merged into metadata.
• Anthropic: a non-list :tools option (such as nil) no longer raises; tools
  are omitted.
• Google: streaming tolerates chunks with no candidates, content, or parts.
• Google: countTokens sends exactly one of contents or
  generateContentRequest.
• OpenAI: a bare-string :image_url block is handled instead of crashing.
• OpenAI: model inference is limited to o1/o3/o4/chatgpt prefixes, so
  other models are not misrouted.
• OpenAI: parsing a chunk with no tool calls returns [], not an error.
• xAI: ChatCompletionsModel.new/1 no longer crashes on streaming: true.
• Moonshot: the tool-name regex accepts short and digit/hyphen-leading names.
• Provider runtime: stream-metadata returns %{} instead of crashing when an
  adapter has no metadata function.
• Cached models keep usage cost on a cache miss, for both stream and
  stream_events.

Agents and middleware:

• interrupt_before/interrupt_after: :all is preserved instead of becoming
  [:all], which had disabled all human-in-the-loop interrupts.
• Structured final-response extraction handles string-keyed state instead of
  crashing.
• list_async_tasks refreshes live status before filtering, not stale status.
• A configured subagent-output response that is not a map or function is honored,
  not dropped.
• The tool emulator falls back to "unknown_tool" when a tool call has no name.

Graph:

• Validation-node task exits become error messages instead of crashing the node.
• Pending checkpoint-map merging tolerates a missing configurable key.
• Delta channels keep nil/false overwrite values instead of resetting to the
  initial value.
• input_channels hides private channels (such as __node_outputs__) when there
  is no input_schema.
• An empty-list edge condition is treated as membership, not a match-anything map.
• add_messages honors the last remove_all marker, not the first.
• OpenAI message formatting tags tool calls as "tool_call", not "tool_calls".
• ServerInfo.User Access no longer leaks struct-field keys into user metadata.

Memory, retrieval, and indexing:

• Ecto memory applies default_ttl on write. Refresh-on-read updates only
  expires_at, not updated_at.
• ETS chat history no longer drops messages under concurrent add_messages;
  writes are atomic.
• Indexing without a record manager deduplicates documents that share an id.
• ETS memory namespace listing ignores unknown match-condition types instead of
  crashing.
• Memory metadata filters match a plain-map value by equality instead of always
  failing.
• Vector-store SQL filters render $and/$or/$not.
• The policy retriever honors :similarity_score and score_threshold.
• The SQL $like filter keeps the user pattern verbatim, matching ETS like.
• ETS vector store stringifies ids in delete/get_by_ids, so non-string ids
  match.
• File-search snippets slice with correct offsets, fixing garbled multibyte text.
• add_start_index reports a character index, not a byte offset.

Rate limiting:

• The rate-limited wrapper streams through ChatModel.stream/3 instead of
  degrading to invoke when the provider module is not loaded.
• Token-bucket acquire rejects negative or non-integer timeouts and invalid
  modes up front.
• Retry delays are re-clamped to max_delay after jitter, including the
  zero-backoff path.

Serialization and schema:

• Maps with colliding atom/string keys raise instead of silently dropping one.
• The pretty JSON encoder escapes all control characters.
• Structured-output oneOf variants get distinct spec names.
• A nullable typeless tool field becomes anyOf[…, null], not null-only.
• Checkpoint config normalization returns %{} when configurable is nil.
• MapAccess.first returns a false/nil value instead of the default.
• Empty-string schema defaults are emitted, not dropped.
• Strict tool-schema rendering keeps user keys with nil values.
• Schema fields given as 2-tuples normalize instead of crashing.
• Tracing custom_fields skips non-pair list entries instead of crashing.

Core messages and text:

• XML output parsing slices on byte offsets, fixing multibyte corruption.
• Tool-result truncation backs off to a valid UTF-8 boundary.
• Trimming with :last keeps the last words, not the first.
• Usage subtraction clamps right-only token counts to zero, including nested maps.
• The drop_oldest mux drops the newest item instead of erroring when the buffer
  is full.
• Prompt partials and the simple template renderer no longer mishandle supplied
  or brace values.
• Partial JSON repair is no longer cubic on long input.
• Fixed assorted dead and edge-case clauses: agent decision normalization,
  transient-error and MFA retry predicates, and the HTML header splitter.

Sandbox and shell:

• Docker edit/5 starts the container once and threads it through
  read/write/execute. Edits previously hit throwaway containers and leaked
  containers.
• Docker execute/read truncation respects UTF-8 codepoint boundaries.
• The Docker sandbox prints the entry type before the path, so ls/glob handle
  paths containing |.
• File-formatting long-line chunking splits on character boundaries, not raw
  bytes.
• A host shell command no longer crashes when the policy timeout is nil.
• Shell host-executor and session temp files are cleaned up even on timeout or
  kill.

Changed

• Default operation timeout raised from 5 seconds to 5 minutes for runnable
  batch/map/parallel/fallback and the agent GenServer.call. An explicit
  :timeout still overrides it.

Internal

• Removed dead clauses and other compiler-warning sources. mix compile and
  mix test now run clean.
