    Synapse 1.21.2 (2020-10-15)

    🛠 Debian packages and Docker images have been rebuilt using the latest versions of dependency libraries, including authlib 0.15.1. Please see bugfixes below.

    🔒 Security advisory

    • HTML pages served via Synapse were vulnerable to cross-site scripting (XSS) attacks. All server administrators are encouraged to upgrade. (#8444) (CVE-2020-26891)

    This fix was originally included in v1.21.0 but was missing a security advisory.

    This was reported by Denis Kasak.

    🛠 Bugfixes

    • 🛠 Fix rare bug where sending an event would fail due to a racey assertion. (#8530)
    • ⚡️ An updated version of the authlib dependency is included in the Docker and Debian images to fix an issue using OpenID Connect. See #8534 for details.

    Synapse 1.21.1 (2020-10-13)

    🚀 This release fixes a regression in v1.21.0 that prevented debian packages from being built. It is otherwise identical to v1.21.0.

    Synapse 1.21.0 (2020-10-12)

    No significant changes since v1.21.0rc3.

    As noted in 🚀 v1.20.0, 🚀 a future release will drop support for accessing Synapse's 📄 Admin API under the /_matrix/client/* endpoint prefixes. At that point, the Admin API will only be accessible under /_synapse/admin.

    Synapse 1.20.1 (2020-09-24)

    🛠 Bugfixes

    • Fix a bug introduced in v1.20.0 which caused the synapse_port_db script to fail. (#8386)
    • 🛠 Fix a bug introduced in v1.20.0 which caused variables to be incorrectly escaped in Jinja2 templates. (#8394)

    Synapse 1.20.0 (2020-09-22)

    No significant changes since v1.20.0rc5.

    ⚠ Removal warning

    Historically, the Synapse Admin 📄 API has been accessible under the /_matrix/client/api/v1/admin, /_matrix/client/unstable/admin, /_matrix/client/r0/admin and 🚀 /_synapse/admin prefixes. In a future release, we will be dropping support for accessing Synapse's Admin API using the /_matrix/client/* prefixes.

    From that point, the Admin API will only be accessible under /_synapse/admin. 🔒 This makes it easier for homeserver admins to lock down external access to the Admin API endpoints.
