([\#11696](https://github.com/matrix-org/synapse/issues/11696)) -Synapse 1.49.2 (2021-12-21) -=========================== - -This release fixes a regression introduced in Synapse 1.49.0 which could cause `/sync` requests to take significantly longer. This would particularly affect "initial" syncs for users participating in a large number of rooms, and in extreme cases, could make it impossible for such users to log in on a new client. - -**Note:** in line with our [deprecation policy](https://matrix-org.github.io/synapse/latest/deprecation_policy.html) for platform dependencies, this will be the last release to support Python 3.6 and PostgreSQL 9.6, both of which have now reached upstream end-of-life. Synapse will require Python 3.7+ and PostgreSQL 10+. - -**Note:** We will also stop producing packages for Ubuntu 18.04 (Bionic Beaver) after this release, as it uses Python 3.6. - -Bugfixes --------- - -- Fix a performance regression in `/sync` handling, introduced in 1.49.0. ([\#11583](https://github.com/matrix-org/synapse/issues/11583)) - -Internal Changes ----------------- - -- Work around a build problem on Debian Buster.

The first was to ensure that changes are checked by -multiple authors before being committed (everyone makes mistakes!) and the second -was visibility of the documentation. Not everyone knows that Synapse has some very -useful information hidden away in its GitHub wiki pages. Bringing them to the -documentation website should help with visibility, as well as keep all Synapse documentation -in one, easily-searchable location. - -Note that contributions to the documentation website happen through [GitHub pull -requests](https://github.com/matrix-org/synapse/pulls). Please visit [#synapse-dev:matrix.org](https://matrix.to/#/#synapse-dev:matrix.org) -if you need help with the process! - - -Synapse 1.49.0rc1 (2021-12-07) -============================== - -Features --------- - -- Add [MSC3030](https://github.com/matrix-org/matrix-doc/pull/3030) experimental client and federation API endpoints to get the closest event to a given timestamp.

However, critical security vulnerabilities in dependencies or other unanticipated circumstances may arise which necessitate breaking compatibility earlier. - -We intend to continue producing .deb packages for Debian 9 (Stretch) and Ubuntu 16.04 (Xenial) through the transition period. - -Removal warning ---------------- - -The old [Purge Room API](https://github.com/matrix-org/synapse/tree/master/docs/admin_api/purge_room.md) -and [Shutdown Room API](https://github.com/matrix-org/synapse/tree/master/docs/admin_api/shutdown_room.md) -are deprecated and will be removed in a future release.

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.

Introduced in v1.11.0. - -Synapse 1.12.0 (2020-03-23) -=========================== - -Debian packages and Docker images are rebuilt using the latest versions of -dependency libraries, including Twisted 20.3.0. **Please see security advisory -below**. - -Potential slow database update during upgrade ---------------------------------------------- - -Synapse 1.12.0 includes a database update which is run as part of the upgrade, -and which may take some time (several hours in the case of a large -server). Synapse will not respond to HTTP requests while this update is taking -place. 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.

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.

Introduced in v1.11.0. + +Synapse 1.12.0 (2020-03-23) +=========================== + +Debian packages and Docker images are rebuilt using the latest versions of +dependency libraries, including Twisted 20.3.0. **Please see security advisory +below**. + +Potential slow database update during upgrade +--------------------------------------------- + +Synapse 1.12.0 includes a database update which is run as part of the upgrade, +and which may take some time (several hours in the case of a large +server). Synapse will not respond to HTTP requests while this update is taking +place. 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.

However, critical security vulnerabilities in dependencies or other unanticipated circumstances may arise which necessitate breaking compatibility earlier. + +We intend to continue producing .deb packages for Debian 9 (Stretch) and Ubuntu 16.04 (Xenial) through the transition period. + +Removal warning +--------------- + +The old [Purge Room API](https://github.com/matrix-org/synapse/tree/master/docs/admin_api/purge_room.md) +and [Shutdown Room API](https://github.com/matrix-org/synapse/tree/master/docs/admin_api/shutdown_room.md) +are deprecated and will be removed in a future release.
