([\#7558](https://github.com/matrix-org/synapse/issues/7558)) + + +Synapse 1.13.0 (2020-05-19) +=========================== + +This release brings some potential changes necessary for certain +configurations of Synapse: + +* If your Synapse is configured to use SSO and have a custom + `sso_redirect_confirm_template_dir` configuration option set, you will need + to duplicate the new `sso_auth_confirm.html`, `sso_auth_success.html` and + `sso_account_deactivated.html` templates into that directory. +* Synapse plugins using the `complete_sso_login` method of + `synapse.module_api.ModuleApi` should instead switch to the async/await + version, `complete_sso_login_async`, which includes additional checks. The + former version is now deprecated. +* A bug was introduced in Synapse 1.4.0 which could cause the room directory + to be incomplete or empty if Synapse was upgraded directly from v1.2.1 or + earlier, to versions between v1.4.0 and v1.12.x. + +Please review the [upgrade notes](docs/upgrade.md) for more details on these changes +and for general upgrade guidance. + + +Notice of change to the default `git` branch for Synapse +-------------------------------------------------------- + +With the release of Synapse 1.13.0, the default `git` branch for Synapse has +changed to `develop`, which is the development tip. This is more consistent with +common practice and modern `git` usage. + +The `master` branch, which tracks the latest release, is still available. It is +recommended that developers and distributors who have scripts which run builds +using the default branch of Synapse should therefore consider pinning their +scripts to `master`. + + +Internal Changes +---------------- + +- Update the version of dh-virtualenv we use to build debs, and add focal to the list of target distributions.

For imformation on seeing if you are affected, and workaround if you +are, see the [upgrade notes](docs/upgrade.md#upgrading-to-v1120). + +Security advisory +----------------- + +Synapse may be vulnerable to request-smuggling attacks when it is used with a +reverse-proxy. The vulnerabilties are fixed in Twisted 20.3.0, and are +described in +[CVE-2020-10108](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10108) +and +[CVE-2020-10109](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10109). +For a good introduction to this class of request-smuggling attacks, see +https://portswigger.net/research/http-desync-attacks-request-smuggling-reborn. + +We are not aware of these vulnerabilities being exploited in the wild, and +do not believe that they are exploitable with current versions of any reverse +proxies. Nevertheless, we recommend that all Synapse administrators ensure that +they have the latest versions of the Twisted library to ensure that their +installation remains secure. + +* Administrators using the [`matrix.org` Docker + image](https://hub.docker.com/r/matrixdotorg/synapse/) or the [Debian/Ubuntu + packages from + `matrix.org`](https://matrix-org.github.io/synapse/latest/setup/installation.html#matrixorg-packages) + should ensure that they have version 1.12.0 installed: these images include + Twisted 20.3.0. +* Administrators who have [installed Synapse from + source](https://matrix-org.github.io/synapse/latest/setup/installation.html#installing-from-source) + should upgrade Twisted within their virtualenv by running: + ```sh + <path_to_virtualenv>/bin/pip install 'Twisted>=20.3.0' + ``` +* Administrators who have installed Synapse from distribution packages should + consult the information from their distributions. + +The `matrix.org` Synapse instance was not vulnerable to these vulnerabilities. + +Advance notice of change to the default `git` branch for Synapse +---------------------------------------------------------------- + +Currently, the default `git` branch for Synapse is `master`, which tracks the +latest release. + +After the release of Synapse 1.13.0, we intend to change this default to +`develop`, which is the development tip. This is more consistent with common +practice and modern `git` usage. + +Although we try to keep `develop` in a stable state, there may be occasions +where regressions creep in. Developers and distributors who have scripts which +run builds using the default branch of `Synapse` should therefore consider +pinning their scripts to `master`. + + +Synapse 1.12.0rc1 (2020-03-19) +============================== + +Features +-------- + +- Changes related to room alias management ([MSC2432](https://github.com/matrix-org/matrix-doc/pull/2432)): + - Publishing/removing a room from the room directory now requires the user to have a power level capable of modifying the canonical alias, instead of the room aliases.
