Azure Functions Core Tools: baixar versions anteriors

Azure Functions CLI 4.15.2
Host Version
- Host Runtime Version: 4.1053.200
- In-Proc CLI:
- CLI Version: 4.8.0
- Host Runtime Version: 4.52.100 (includes 4.852.100, 4.652.100)
Changes
- Add Dockerfile generation (func init --docker / --docker-only) for .NET 11 isolated projects using the chiseled mcr.microsoft.com/azure-functions/dotnet-isolated:4-dotnet-isolated11.0-chiseled base image. (#5599)
- Require explicit confirmation before func bundles download --force recursively deletes an existing extension bundle directory. (#5666)

Azure Functions CLI 4.15.0
Host Version
- Host Runtime Version: 4.1053.200
- In-Proc CLI:
- CLI Version: 4.8.0
- Host Runtime Version: 4.52.100 (includes 4.852.100, 4.652.100)
Changes
- Add explicit .NET 11 C# isolated initialization with updated templates. The default remains .NET 10; .NET 11 F# scaffolding and Docker support are not yet available.
- Support worker-indexed .NET isolated build and publish outputs in func pack, including --no-build, without requiring a separate functions.metadata file.
- Fixed Python native dependency builds to inherit authenticated pip indexes in Docker containers (#5574)
- Make host.json optional across func publish, and pack (#5488)
- Fixed func kubernetes deploy failing with Invalid property identifier character: { for dotnet-isolated projects with more than one function. The print-functions.sh script previously used a sed command that only captured the last function name and produced malformed JSON; replaced with awk to correctly key each function object by its name field. (#3585)

Azure Functions CLI 4.14.0
Host Version
- Host Runtime Version: 4.1052.200
- In-Proc CLI:
- CLI Version: 4.7.0
- Host Runtime Version: 4.51.100 (includes 4.851.100, 4.651.100)
Changes
- Added durable-functions dependency to package.json when creating Node.js durable function templates (#5495)
- Changed func start to bind to the IPv4 loopback address (127.0.0.1) by default instead of 0.0.0.0, and added an opt-in --address flag (and Host.LocalHttpAddress setting in local.settings.json) to override the bind address (#5484)
- Potential breaking change: the host now binds to 127.0.0.1 by default, so it is only reachable from the local machine. Setups that relied on binding to 0.0.0.0 — for example reaching the host from outside a Docker container via a published port — will no longer connect. Workaround: start the host with func start --address 0.0.0.0 (or set "LocalHttpAddress": "0.0.0.0" under Host in local.settings.json) to restore the previous behavior.

Azure Functions CLI 4.13.0
Host Version
- Host Runtime Version: 4.1051.300
- In-Proc CLI:
- CLI Version: 4.7.0
- Host Runtime Version: 4.51.100 (includes 4.851.100, 4.651.100)
Changes

- Bumped https-proxy-agent dependency (#5335)
- Updated target framework to .NET 10 (#4850)
- Fix Flex Health Check to use defaultHostName instead of enabledHostNames (#5462)
- Added durable-functions dependency to package.json when creating Node.js durable function templates (#5495)
- Changed func start to bind to the IPv4 loopback address (127.0.0.1) by default instead of 0.0.0.0, and added an opt-in --address flag (and Host.LocalHttpAddress setting in local.settings.json) to override the bind address (#5484)
- Potential breaking change: the host now binds to 127.0.0.1 by default, so it is only reachable from the local machine. Setups that relied on binding to 0.0.0.0 — for example reaching the host from outside a Docker container via a published port — will no longer connect. Workaround: start the host with func start --address 0.0.0.0 (or set "LocalHttpAddress": "0.0.0.0" under Host in local.settings.json) to restore the previous behavior.

Azure Functions CLI 4.12.1
Host Version
- Host Runtime Version: 4.1048.200
- In-Proc CLI:
- CLI Version: 4.6.0
- Host Runtime Version: 4.49.100 (includes 4.849.100, 4.649.100)
Changes
- No changes to core CLI, in-proc CLI updated to 4.6.0 with host version 4.49.100

Azure Functions CLI 4.12.0
Host Version
- Host Runtime Version: 4.1048.200
- In-Proc CLI:
- CLI Version: 4.5.0
- Host Runtime Version: 4.48.100 (includes 4.848.100, 4.648.100)
Changes
- Fix HttpsProxyAgent is not a constructor error in install.js when installing behind a proxy (https-proxy-agent v9 requires a named import).
- Remove azure-functions-core-tools from the devDependencies of generated function app templates (package-js.json, package-js-v4.json, package-ts.json, package-ts-v4.json). Users get the CLI from their system install; pulling it in again via npm install doubled disk usage and made every project's install fragile to Core Tools postinstall regressions.
Preview Feature
- Add preview Go language support to func init, func start, func pack, and func publish (#4875, #4892, #4943). Behaviour, build/publish flags, and deployment layout may change before GA.

In the meantime, please use alternate channels. We appreciate your patience and understanding.

Change Notes
