With the release of version `0.27.0` it is now removed. +A successful HTTP request to any of the `v1` endpoints will log and return a deprecation message while responding with a status code of `410`. +Please ensure you switch to the `v2` equivalent endpoint in your integrations before upgrading. + +### Alertmanager support for all UTF-8 characters in matchers and label names + +Starting with Alertmanager `v0.27.0`, we have a new parser for matchers that has a number of backwards incompatible changes. While most matchers will be forward-compatible, some will not. Alertmanager is operating a transition period where it supports both UTF-8 and classic matchers, so **it's entirely safe to upgrade without any additional configuration**. With that said, we recommend the following: + +- If this is a new Alertmanager installation, we recommend enabling UTF-8 strict mode before creating an Alertmanager configuration file. You can enable strict mode with `alertmanager --config.file=config.yml --enable-feature="utf8-strict-mode"`. + +- If this is an existing Alertmanager installation, we recommend running the Alertmanager in the default mode called fallback mode before enabling UTF-8 strict mode. In this mode, Alertmanager will log a warning if you need to make any changes to your configuration file before UTF-8 strict mode can be enabled. **Alertmanager will make UTF-8 strict mode the default in the next two versions**, so it's important to transition as soon as possible. + +Irrespective of whether an Alertmanager installation is a new or existing installation, you can also use `amtool` to validate that an Alertmanager configuration file is compatible with UTF-8 strict mode before enabling it in Alertmanager server by running `amtool check-config config.yml` and inspecting the log messages. + +Should you encounter any problems, you can run the Alertmanager with just the classic parser enabled by running `alertmanager --config.file=config.yml --enable-feature="classic-mode"`. If so, please submit a bug report via GitHub issues. + ## 0.26.0 / 2023-08-23 * [SECURITY] Fix stored XSS via the /api/v1/alerts endpoint in the Alertmanager UI.
