tengu_media_byte_cap ◇ The size limit on images and media sent to the model now comes from new remote settings, with checks and a separate second limitv2.1.191 → v2.1.296 ○gone AND v2.1.299 tengu_mellow_beacon ◇ A server-controlled setting can make some background requests to the model point back to the reply they came fromv2.1.288 → v2.1.308 ◆in the build AND v2.1.288 tengu_mellow_heron ◇ Claude Code can now track prompts that were merged or queued together, for rewinding and spotting unanswered turns, when a switch is onv2.1.299 → v2.1.308 ◆in the build AND v2.1.299 tengu_mellow_hollerith ◇ New built-in 'Claude Test' plugin runs plain-language specs against your local dev server in a real browser and reports PASS/FAILv2.1.274 → v2.1.295 ○gone AND v2.1.300 tengu_melodic_octopus ◇ When --worktree uses a pull or merge request number, Claude Code fetches the full PR reference and refuses if it can't tell which commit is meantv2.1.300 → v2.1.308 ◆in the build AND v2.1.302 tengu_melodic_wolf ◇ Subagent results can be tagged to show which parts Claude Code wrote versus the model.v2.1.242 → v2.1.308 ◆in the build AND v2.1.277 tengu_memdir_write_lint ◇ A new check can refuse or clean memory files containing invisible characters or tag-like text; it falls back to off unless enabled remotelyv2.1.284 → v2.1.308 ◆in the build AND v2.1.284 tengu_memory_bulk_inflate ◇ Team memory bulk-inflate telemetry now only fires for non-account memory, plus a new bail-outv2.1.161 → v2.1.308 ◆in the build AND v2.1.275 tengu_memory_stream_list ◇ Default true. When on, memory store sync first tries to list a store's entries through the backend's metadata stream (exportMetadata), falling back to the paged list call when that fails. Off, or with CLAUDE_CODE_DISABLE_MEMORY_STREAM_LIST set, every listing uses the paged list.v2.1.210 → v2.1.308 ◆in the build AND v2.1.210 tengu_mermaid_mod ◇ Mermaid flowcharts and sequence diagrams in replies now render as text art in the terminalnever mined ·never mined AND v2.1.277 tengu_merry_popcorn ◇ Claude Code can now label each approval of a tool call as coming from a person, a classifier, a mode or a hookv2.1.288 → v2.1.308 ◆in the build AND v2.1.288 tengu_misty_aurora ◇ In remote sessions, a permission request left unanswered long enough can be declined automatically, with Claude told not to retryv2.1.292 → v2.1.308 ◆in the build AND v2.1.292 tengu_misty_sunbeam ◇ When a PDF has too many pages to read at once, Claude Code can read the first pages and report the total instead of failingv2.1.300 → v2.1.308 ◆in the build AND v2.1.300 tengu_modular_seal ◇ Claude Code can now count Claude's refusals since the conversation was last summarised, behind a setting that is off by defaultv2.1.295 → v2.1.308 ◆in the build AND v2.1.295 tengu_moonlit_island ◇ Claude Code can mark a round of polled events as declared and hand them to Claude in one message, but only behind a remote switchv2.1.293 → v2.1.308 ◆in the build AND v2.1.293 tengu_moonlit_lagoon ◇ A timing check used while Claude Code is idle or waiting on you now first consults a server-controlled switchv2.1.287 → v2.1.308 ◆in the build AND v2.1.287 tengu_moonlit_lobster ◇ Changing the model now refreshes the data Claude Code loaded at startup, as part of reworked model-switch handlingv2.1.285 → v2.1.287 ○gone AND v2.1.285 tengu_moonlit_toucan ◇ Claude Code now counts turns since a person last wrote and can act once a limit is reached, but this is off unless switched on remotelyv2.1.296 → v2.1.308 ◆in the build AND v2.1.296 tengu_morning_brief_config ◇ Default null. An object whose skillPrompt string replaces the built-in prompt of the /morning skill when, after trimming, it is 500 to 50000 characters long. A valid CLAUDE_CODE_MORNING_BRIEF_PROMPT takes precedence, and the flag is not read when the entrypoint is remote_cowork or remote_trigger.v2.1.207 ○gone AND v2.1.207 tengu_morning_brief_skill ◇ Default false. Enables the /morning skill (render a morning brief as an HTML artifact, or set it up as a recurring weekday task) when CLAUDE_CODE_IS_COWORK is true and the entrypoint is not remote_cowork or remote_trigger. A true CLAUDE_CODE_ENABLE_MORNING_BRIEF enables the skill in those sessions and entrypoints regardless of this flag.v2.1.207 ○gone AND v2.1.207 tengu_mossy_crown ◇ A new accessFallbackModels setting lists models Claude Code may fall back to when the main model can't be usedv2.1.292 → v2.1.308 ◆in the build AND v2.1.299 tengu_mossy_gray ◇ A limit set at 2000 for every provider can now be removed by a server-side switch when Claude Code runs interactivelyv2.1.299 → v2.1.308 ◆in the build AND v2.1.299 tengu_mossy_thrush ◇ When a further server-side switch is on, the changed-file check can judge files through an outputs link and count each outcomev2.1.300 → v2.1.308 ◆in the build AND v2.1.300 tengu_moth_lantern ◇ Default false. When on and CLAUDE_MEMORY_STORES is unset or blank, a saved org memory store selection for the current account (orgMemorySelection) is sent when Claude Code requests the org memory credential, and cached store-picker data is returned alongside the org memory mounts. When off, a saved selection is sent only if it is public_projects.v2.1.213 → v2.1.217 ○gone AND v2.1.213 tengu_mutable_teapot ◇ Claude Code can now remove ask rules that come from MCP server policy before sending your permission rules to the auto mode classifiernever mined ·never mined AND v2.1.282 tengu_nankeen_kestrel ◇ Windows sandbox TLS interception could use a persistent managed certificate authority, but that path is disabled here.v2.1.212 → v2.1.308 ◆in the build AND v2.1.221 tengu_neapolitan ◇ The checks deciding whether subagents are offered remote isolation gained two new conditions at the frontv2.1.178 → v2.1.308 ◆in the build AND v2.1.288 tengu_nifty_finch ◇ Claude Code can now work out an alternate model to suggest from the current one, behind a server switchv2.1.286 → v2.1.308 ◆in the build AND v2.1.286 tengu_nimble_wren ◇ The built-in web-fetch helper now uses Haiku when certain model and provider checks pass, and is told not to retry sites that refuse itv2.1.300 → v2.1.308 ◆in the build AND v2.1.302 tengu_noble_mountain ◇ Write tool now accepts file_text, file_content, and path as aliases for content and file_path, rewriting input before plugin hooks see itv2.1.280 → v2.1.308 ◆in the build AND v2.1.280 tengu_noble_snowflake ◇ A new telemetry event, tengu_bridge_transcript_deferral, reports each stage of Remote Control's deferred transcript uploadv2.1.281 → v2.1.308 ◆in the build AND v2.1.281 tengu_noble_wozniak ◇ When the agents view opens, background housekeeping can now wait until you have trusted the folder instead of starting straight awayv2.1.300 → v2.1.308 ◆in the build AND v2.1.300 tengu_observer_agents_enabled ◇ Default true. Kill switch for observer agents, the observer field in an agent definition: they also require CLAUDE_CODE_EXPERIMENTAL_OBSERVER_AGENTS, and a false value here leaves every agent unobserved. The same gate also switches a second code path elsewhere in the bundle.v2.1.200 → v2.1.308 ◆in the build AND v2.1.200 tengu_observer_subagent_fanout ◇ Default true. When false, an observer pairing is not extended to the subagents an observed agent spawns.
