3.260.0

3.260.0 (2026-08-28)

Features

• [cli/deployment] Make pulumi deployment settings get render every source kind and show environment variable values, changing the --output=json shape of environmentVariables from a list of names to a list of objects #24284
• [sdk/go] Support Go 1.27 #24401
• [cli/state] Add pulumi state promote to turn stateful snippets into Pulumi program code #24453

Bug Fixes

• [engine] Replace resources whose deletedWith target is being replaced, instead of leaving them orphaned in state #23818
• [sdk/python] Serialize typed object stack outputs with their wire-format (camelCase) property names, matching other language SDKs #24246
• [cli/neo] Cancelling a task now interrupts a running local tool call instead of waiting for it to finish #24268
• [programgen/python] Access schema properties whose names contain hyphens as attributes under their Python names instead of subscripting #24300
• [programgen/go] Generate valid struct field names for properties whose names contain hyphens #24300
• [sdkgen/nodejs] Quote property names that are not legal identifiers (e.g. kebab-case) in generated declarations and use bracket access for them #24300
• [cli/neo] Cancelling a local tool call no longer leaves the TUI stuck on "Thinking..." with input blocked #24318
• [sdk/go] Use resolved environment names when evaluating ESC imports #24375
• [codegen/pcl] Allow output-typed values for the id attribute of a read resource #24386
• [sdkgen/nodejs] Register resolvers for output-only properties in generated Resource.get so they resolve as unknown during preview when the id is unknown #24386
• [engine] Avoid replacing imported resources when an input changes from plain to a secret or output-wrapped value with the same inner value #24387
• [backend/diy] Keep DIY backend stacks readable when checkpoint compression transitions fail #24383
• [cli/stack] Give a clearer error message when selecting a stack by name outside a directory with a Pulumi.yaml project file #24394
• [sdk/python] Propagate runtime context across thread boundaries #24403
• [programgen/python] Name plain function input object types without the Args suffix, matching the name the generated SDK exports #24440
• [cli/new] Reject zip template entries that resolve outside the extraction directory #24447
• [cli/package] Keep a package's pluginDownloadURL in SDKs regenerated by pulumi install #24432
• [sdk/python] Preserve all providers passed to remote components in Python programs #24443
• [sdkgen] Apply schema defaults to generated Python and Node.js function inputs #24452
• [programgen/python] Mark required component inputs as required in generated Python TypedDicts #24459
• [programgen/python] Add type annotations for config variables default values coming from invokes #24464
• [programgen/python] Generate valid Python when a component with inputs instantiates another component #24466
• [cli/neo] Stop the running local tool immediately when a Neo task is cancelled and report it as cancelled #24470
• [programgen/python] Support final argument expansion for min and max in Python programs #24471

Improvements

• [cli] Treat adjacent character swaps as a single typo when suggesting commands #23899
• [sdk/python] Correctly resolve discriminated unions by their tag #24352
• [sdk/python] Allow transforms to be mocked #24406
• [sdk/nodejs] Allow transforms to be mocked #24415
• [sdk/go] Allow transforms to be mocked #24416
• [sdkgen] Allow hyphens in the member segment of tokens, so resource, object type and function names can be kebab-case #24440
• [cli] Print secret provider information with other stack information #24430
• [auto/python] Allow refresh, preview_refresh, and preview_destroy to request rich diffs #24445
• [engine] Cache provider mapping results on disk so repeated plans do not boot a provider to re-fetch an unchanged mapping #24462
• [sdk/python] Improve stack traces for providers #24465

Miscellaneous

• [sdk/dotnet] Upgrade dotnet to v3.113.0 #24441
