  #22771

• [cli/cloud] Add --paginate to pulumi cloud api: follow continuation cursors,
  accumulate items into a single JSON envelope, and surface progress
  events to stderr with --emit-events (page, complete, truncated,
  partial_failure, cancelled).

  #22772

Bug Fixes

• [cli] Fix the pulumi neo shell tool to honor the agent-supplied timeout and to terminate the whole process tree (and unblock cmd.Wait) when the deadline fires, so commands like kubectl logs -f no longer hang Neo indefinitely.
  #22820

• [cli] Surface the error and exit when pulumi neo fails to create the underlying task, instead of leaving the TUI stuck in Thinking…

  #22834

• [programgen/{nodejs,python}] Fix programgen to emit the right length check for string length
  #22802

Miscellaneous

  body, and response schema of any Pulumi Cloud API operation, with
  text, markdown, and JSON output

  #22770

• [cli/cloud] Add pulumi cloud api list for browsing every endpoint exposed by the Pulumi
  Cloud OpenAPI spec, with table and JSON output

  #22769

Bug Fixes

• [engine] Revert changes to property path parsing that resulted in errors for currently valid paths

3.233.0 (2026-04-30)

Features

• [auto/python] Expose the auto-generated Pulumi CLI interface as workspace.cli_api
  #22638

• [cli] Add encrypted logging to ~/.pulumi/logs; use the PULUMI_ENABLE_AUTOMATIC_LOGGING feature flag to turn it on
  #22494

• [cli] Implement the filesystem__grep and filesystem__content_replace local tools
  for pulumi neo. grep runs a regex search across files in the project root
  with an optional include glob filter and returns results in path:lineno: line
  form. content_replace performs a literal multi-file search-and-replace with a
  file_pattern glob and dry_run preview mode. Both tools skip binary files,
  hidden directories, and node_modules, and reject paths outside the project
  root. Their input schemas match the cloud-side tool definitions.

  #22655

• [cli] Add pulumi_preview and pulumi_up as local tools for the experimental pulumi neo
  agent. The Neo TUI renders a persistent bordered block for each operation that
  streams changed resources and diagnostics as the engine runs and finalizes with a
  summary of the op counts. Hidden behind PULUMI_EXPERIMENTAL.

  #22697

• [engine] Add List to the provider protocol and schema
  #22693

Bug Fixes

• [engine] Return a clear error when two installed plugins claim the same default provider package name (for example, a native scaleway provider alongside a terraform-provider bridge parameterized as scaleway) instead of panicking with "Should not have seen an older plugin if sorting is correct!"
  #22679

• [programgen] Do not wrap a call(...) on a method whose return type is marked plain in an Output. Previously
  PCL bound every method call's return type as Output<T>, which caused downstream program-gen
  to emit broken .apply(...)/.ApplyT(...) traversals against plain struct returns (e.g.
  methods with liftSingleValueMethodReturns=true or ReturnTypePlain=true).

  #22696

• [backend/diy] When using a backend url containing creds (e.g. PostgreSQL conn string), mask user:pass as in lock-related error messages
  #22701

• [codegen/go] Generate unqualified Provider references for the package's own provider resource. Previously
  the Go codegen always emitted <pkg>.Provider even when the reference appeared inside <pkg>
  itself, producing identifiers that would not compile. Affects generated code for method return
  types (and other schema positions) that reference pulumi:providers:<pkg>.

  #22696

• [codegen/nodejs] Generate unqualified Provider references for the package's own provider resource when emitting
  TypeScript code inside that package. Previously the generator always qualified the name as
  <pkg>.Provider, which does not resolve when no <pkg> namespace import is in scope.

  #22696

• [codegen/nodejs] Import the correct class name for a provider resource. Imports for pulumi:providers:<pkg> used
  the title-cased package name instead of Provider, producing a phantom identifier that clashed
  with the containing package's component/resource classes.

  #22696

• [programgen/nodejs] Emit await for call(...) invocations of methods whose return type is marked plain, and
  force the generated program into an async export = async () => ... wrapper whenever such a
  call is present. The Node SDK returns Promise<T> for plain methods; previously program-gen
  used the result directly, which did not match its runtime type.

  #22696

• [codegen/python] Avoid a self-import (import pulumi_<pkg> inside pulumi_<pkg>/<module>.py) when referencing
  the package's own provider resource. Python referenced the Provider as pulumi_<pkg>.Provider
  even inside that package, which caused a circular import at runtime.

  #22696

• [sdk/python] Reduce internal Output[T] data to a single asyncio.Future
  #22661

• [sdkgen/{nodejs,python}] Generate optional input types that accept undefined/None values
  #22552

Miscellaneous

• [auto/go] Drop the "With" prefix from generated option helpers so they match the naming of the existing optXxx packages
  #22682

3.232.0 (2026-04-22)

Features

• [cli] Add an experimental pulumi neo command that creates a Pulumi Neo agent task in CLI
  tool-execution mode and runs the local tool loop. Filesystem and shell tool calls
  issued by the agent run on the user's machine in their working directory; the
  interactive chat continues to happen in the Pulumi Console at the URL the command
  prints. Hidden behind PULUMI_EXPERIMENTAL.

  #22473

• [cli] Add support for handling user approval requests in the pulumi neo terminal UI.
  When the agent requests confirmation for a sensitive action, the TUI prompts the
  user and forwards their response back to the Pulumi Console. Hidden behind
  PULUMI_EXPERIMENTAL.

  #22589

• [cli] Add an interactive terminal UI for pulumi neo built with bubbletea, rendering
  agent messages, tool calls, and streaming output in the terminal alongside the
  Pulumi Console session. Hidden behind PULUMI_EXPERIMENTAL.

  #22570

• [cli] Switch logging library from glog to slog.

BREAKING: any if logging.V(x) { need to be changed to if logging.V(x).Enabled()

#22548

• [cli] Add a plan-mode toggle to the pulumi neo TUI, bound to Shift+Tab. When
  plan mode is on, Neo explores and asks questions without writing files,
  running pulumi up, or opening PRs, and surfaces an approved plan via a
  dedicated approval gate. The toggle must be set before the first message
  (plan mode is task-level on the wire); approving the proposed plan exits
  plan mode automatically.

  #22634

• [cli] The pulumi neo TUI now drives its "thinking" spinner off a single declarative
  rule (the spinner stays on until a final event — final assistant message, approval
  request, cancellation, or error — lands), so the indicator no longer flickers off
  when the agent hands off tool calls to the CLI or when streaming text arrives
  between tools. Press Esc during a turn to ask the agent to cancel; the label
  switches to "Cancelling..." until the backend acknowledges.

  #22637

• [cli] pulumi neo now executes the edit filesystem tool locally, matching the schema
  and response wording of the upstream mcp-claude-code tool so the agent sees
  identical output whether the call ran on Cloud or CLI. edit performs exact-string
  replacement with occurrence-count validation, and creates a new file when the
  target is missing and old_string is empty.

  #22654

Bug Fixes

• [cli] Render user messages in the pulumi neo TUI as soon as they're submitted
  instead of waiting for the Pulumi Cloud event stream to echo them back.
  The initial prompt passed on the command line also appears in the
  transcript at startup. Self-echoes from the server are de-duplicated;
  user input that originated from another client (e.g. the web UI on the
  same task) still renders.

  #22629

• [cli] Wrap warnings, errors, and user-message bubbles to the terminal width in the
  pulumi neo TUI. Previously these blocks rendered as single long lines that
  were clipped at the right edge of the viewport. On resize, all width-dependent
  transcript blocks (user messages, warnings, errors, assistant messages) now
  reflow to the new terminal width.

  #22635

• [cli/policy] Fix policy ls to use the default org name, not username
  #22656

• [engine] Fix provider registry race condition in parallel delete-before-replace
  #21487

• [engine] Signal providers to cancel before closing them during replacement

• [sdkgen] Error on 'id' in state inputs
  #22636

• [programgen/python] Add necessary casts between types in generated programs
  #22567

• [sdkgen/go] Fix caching of package references to be per-deployment not per-process
  #22170

Miscellaneous

• [java] Upgrade java to v1.25.0
  #22673

• [auto/go] Generate command methods for the Go Automation API codegen
  #22612

• [sdk] Clarify docs on the remote parameter of ComponentResource / Resource in the Node and Python SDKs
