Your installation will continue working as it should and you don't need to do anything. + +For people building commercial products on top of Synapse, they may have to either buy a license exception from Element (from what we hear, the fee depends on the number of monthly-active users on your instance) or they may need to release all related code as free-software (which is what we've been doing at [etke.cc](https://etke.cc/) ([here](https://gitlab.com/etke.cc)) all along). + +We're no lawyers and this changelog entry does not aim to give you the best legal advice, so please research on your own! + +If you'd like to continue using the old Apache-2.0-licensed Synapse (for a while longer anyway), the playbook makes it possible by intruducing a new Ansible variable. You can do it like this: + +```yaml +# Switch the organization that Synapse container images (or source code for self-building) are pulled from. +# Note: the new default value is `element-hq/synapse`. +matrix_synapse_github_org_and_repo: matrix-org/synapse + +# Pin the Synapse version to the last one (v1.98.0) released by the Matrix Foundation +# under the old permissive Apache-2.0 license. +matrix_synapse_version: v1.98.0 +``` + +Notes: + +- if you had already upgraded Synapse to `v1.99.0` by running this playbook, you will still be able to downgrade to `v1.98.0`, because both releases use the same database schema version (`SCHEMA_COMPAT_VERSION = 83` - see [here for v1.98.0](https://github.com/element-hq/synapse/blob/v1.98.0/synapse/storage/schema/__init__.py#L131-L134) and [here for v1.99.0](https://github.com/element-hq/synapse/blob/v1.99.0/synapse/storage/schema/__init__.py#L137-L140)). More details on Synapse's database schema are available [here](https://element-hq.github.io/synapse/develop/development/database_schema.html). It appears that there are no new database migrations introduced in `v1.99.0`, so going back to the older release is possible. This is not guaranteed to hold true for future Synapse releases, so if you're seeing this early-enough, consider pinning the version and organization before re-running the playbook and getting upgraded to the latest version + +- running an outdated homeserver exposes you to security issues and incompatibilities. Only consider doing this as a short-term solution. + # 2024-01-16 ## `Draupnir` has been relicensed to AFL-3.0 diff --git a/roles/custom/matrix-prometheus-services-connect/defaults/main.yml b/roles/custom/matrix-prometheus-services-connect/defaults/main.yml index f06d8da4e..62fb40c4b 100644 --- a/roles/custom/matrix-prometheus-services-connect/defaults/main.yml +++ b/roles/custom/matrix-prometheus-services-connect/defaults/main.yml @@ -12,7 +12,7 @@ matrix_prometheus_services_connect_synapse_rules_enabled: "{{ matrix_prometheus_ # Controls whether the synapse rules shall be downloaded matrix_prometheus_services_connect_synapse_rules_download_enabled: "{{ matrix_prometheus_services_connect_synapse_rules_enabled }}" matrix_prometheus_services_connect_synapse_rules_download_synapse_tag: master -matrix_prometheus_services_connect_synapse_rules_download_src_url: "https://raw.githubusercontent.com/matrix-org/synapse/{{ matrix_prometheus_services_connect_synapse_rules_download_synapse_tag }}/contrib/prometheus/synapse-v2.rules" +matrix_prometheus_services_connect_synapse_rules_download_src_url: "https://raw.githubusercontent.com/{{ matrix_synapse_github_org_and_repo }}/{{ matrix_prometheus_services_connect_synapse_rules_download_synapse_tag }}/contrib/prometheus/synapse-v2.rules" matrix_prometheus_services_connect_synapse_rules_download_dir_path: '' matrix_prometheus_services_connect_synapse_rules_download_owner: '' matrix_prometheus_services_connect_synapse_rules_download_group: '' diff --git a/roles/custom/matrix-synapse/defaults/main.yml b/roles/custom/matrix-synapse/defaults/main.yml index c9c237800..72b8860e7 100644 --- a/roles/custom/matrix-synapse/defaults/main.yml +++ b/roles/custom/matrix-synapse/defaults/main.yml @@ -4,6 +4,17 @@ matrix_synapse_enabled: true +# Specifies which Github organization and repository name Synapse lives at. +# +# This influences: +# - the Github Container Image registry that container images are pulled from (see `matrix_synapse_docker_image_name`) +# - the git repository to code is pulled from when self-building is used (see `matrix_synapse_container_image_self_build_repo`) +# - potentially other roles which need to reference the Synapse git repository +# +# A popular alternative value may be: `matrix-org/synapse`. +# However, do note that the last Synapse version available there is v1.98.0. +matrix_synapse_github_org_and_repo: element-hq/synapse + # renovate: datasource=docker depName=ghcr.io/element-hq/synapse matrix_synapse_version: v1.98.0 @@ -12,7 +23,7 @@ matrix_synapse_uid: '' matrix_synapse_gid: '' matrix_synapse_container_image_self_build: false -matrix_synapse_container_image_self_build_repo: "https://github.com/element-hq/synapse.git" +matrix_synapse_container_image_self_build_repo: "https://github.com/{{ matrix_synapse_github_org_and_repo }}.git" # matrix_synapse_container_image_customizations_enabled controls whether a customized Synapse image will be built. # @@ -72,7 +83,7 @@ matrix_synapse_container_image_customizations_dockerfile_body_custom: '' matrix_synapse_docker_image: "{{ matrix_synapse_docker_image_name_prefix }}{{ matrix_synapse_docker_image_name }}:{{ matrix_synapse_docker_image_tag }}" matrix_synapse_docker_image_name_prefix: "{{ 'localhost/' if matrix_synapse_container_image_self_build else matrix_synapse_docker_image_registry_prefix }}" -matrix_synapse_docker_image_name: element-hq/synapse +matrix_synapse_docker_image_name: "{{ matrix_synapse_github_org_and_repo }}" matrix_synapse_docker_image_tag: "{{ matrix_synapse_version }}" matrix_synapse_docker_image_force_pull: "{{ matrix_synapse_docker_image.endswith(':latest') }}" matrix_synapse_docker_image_registry_prefix: ghcr.io/
