With workers enabled, every Synapse process (the main one and each
worker) maintains its own database connection pool of up to
matrix_synapse_database_cp_max (default: 10) connections. The previous
fixed limit of 500 left little headroom on setups running many workers,
where exhausting it manifests as degraded performance and, reportedly,
E2EE misbehavior.
Size the limit as a 200-connection baseline (for everything else that
talks to Postgres) plus cp_max connections per Synapse process, never
going below the previous value of 500. The stock worker presets stay at
500; setups that raise worker counts (or cp_max) get a limit that grows
accordingly. The new matrix_synapse_workers_total_count variable
reflects what the matrix_synapse_workers_*_count variables ask for; it
does not reflect a manually populated
matrix_synapse_workers_enabled_list, and such setups should override
postgres_max_connections themselves.

The new version supports defining a multiplexed UDP port pool (e.g.
'7882-7892') in livekit_server_config_rtc_udp_port. Previously, the
role's configuration template silently mangled such values into
udp_port: 0. It also gains early validation of the port value.

The CDN section of the federation documentation tells users to set
matrix_synapse_federation_port_enabled: false, which only works because
that recipe moves federation traffic to the client port. Followed
partially (keeping federation on the dedicated federation port behind a
fronting reverse proxy), the same line removes the federation route
entirely and breaks federation. Say so explicitly.

The bridge could only be installed by self-building its source code,
and its upstream repository (on src.miscworks.net) has become
unreachable (the Internet Archive last saw it alive in May 2026),
making installation impossible. The bridge was also based on the
long-unmaintained node-kakao library and carried a warning that using
it may get KakaoTalk accounts banned.
The playbook catches leftover matrix_appservice_kakaotalk_* variables
and points users to the manual uninstallation instructions.

Matrix Authentication Service supports CAPTCHA protection (ReCaptcha
v2, Cloudflare Turnstile, hCaptcha) for certain operations like
self-service password registration, but configuring it required going
through matrix_authentication_service_configuration_extension_yaml.
Expose it via dedicated variables
(matrix_authentication_service_config_captcha_service, _site_key and
_secret_key), validate the service value and key presence, and document
the setup in the captcha documentation page, which so far only covered
Synapse and Dendrite.

Enabling matrix_hookshot_encryption_enabled configures the bridge side
correctly (registration flags, Valkey cache), but hookshot's encryption
also needs the homeserver to support and enable MSC2409 and MSC3202,
which are typically experimental features disabled by default. Nothing
documented that, so the resulting setup silently did not work.
Reference the MSCs in the variable's comment, and show the exact Synapse
settings in the hookshot documentation page. The playbook deliberately
does not auto-enable them: they are experimental homeserver-wide
features, and flipping them from a bridge toggle would be surprising.

etherpad_base_url always ends with a trailing slash, and the playbook
passed it verbatim to jitsi_etherpad_base, which the Jitsi role appends
path segments to (e.g. /p/). The generated Jitsi configuration therefore
contained URLs like https://etherpad.example.com//p/, which can 404
depending on the web server. Strip trailing slashes when wiring.

The autotuning defaults are derived from total system RAM, but every

Add the two remaining hints from the official Synapse backup guide:
- never import a dump into a database that already has tables present
(at best it errors, at worst it causes subtle inconsistencies)
- when restoring a backup older than the server's current state,
truncate e2e_one_time_keys_json before starting Synapse, so used
one-time keys are not re-issued (which causes decryption errors);
our pg_dumpall-based backup commands include that table

Element Web redesigned its welcome page into a built-in component
(element-hq/element-web#33211, first released in spring 2026) and no
longer falls back to loading welcome.html. The custom page the playbook
installed had therefore silently stopped having any effect, and it was a
fork of an upstream file that upstream has deleted (its button icon
assets are already missing from current Element Web builds).
Remove the welcome.html shipping and the variables that only applied to
it (matrix_client_element_welcome_headline, _welcome_text,
_welcome_logo_link, _page_template_welcome_path), rejecting them in
validate_config.yml with pointers to the alternatives. Logo and
background customization keep working through Element Web's branding
options, which the new welcome page still honors. A fully custom page
can be self-hosted and wired via embedded_pages.welcome_url.

Synapse only generates thumbnails of local media at upload time (unless
dynamic_thumbnails is enabled, which the playbook does not do) and no
tooling exists to regenerate them, so restoring a backup left all
previously uploaded local images without thumbnails permanently. The
official Synapse backup guide recommends backing this directory up.
Related to #4004.

The configuration template only rendered a datastore when its for_kinds
list was non-empty, even though the inline documentation (matching
upstream's) describes forKinds: [] as the way to make a datastore
readonly. That made the documented migration scenario impossible: moving
media between the file and s3 datastores while keeping the old one
readable.
Introduce matrix_media_repo_datastore_file_enabled and
matrix_media_repo_datastore_s3_enabled, which default to the previous
kinds-based behavior. A readonly datastore is now expressed by enabling
the datastore explicitly while assigning it no kinds.

synapse-usage-exporter is self-built by default (no upstream image is
published), so every user enabling it runs the git clone/update task. A
docker-src checkout whose files are owned by a different user (e.g. left
behind by an earlier clone) made that task fail: either with a
permission error, or with git's dubious-ownership protection, which
ignores the repository's own configuration and surfaces as a confusing
"'origin' does not appear to be a git repository" error.
Ensure the checkout's ownership recursively before updating it, and mark
the path as a safe.directory for the git invocation itself (via
GIT_CONFIG_* environment variables), so the ownership check cannot
misfire regardless of which user git effectively runs as.

The docs claimed that reverse-proxying "or simply a 302 redirect" needs
no CORS headers. That is only true for reverse-proxying: browsers apply
CORS checks to every response in a redirect chain, so a redirect
response itself must also carry Access-Control-Allow-Origin, otherwise
web clients fail even though the final destination sets the header.

The user-namespace regexes in the mautrix-meta-messenger and
mautrix-meta-instagram registration templates interpolated
the bridge username prefix without regex-escaping it, unlike the
neighboring homeserver domain and appservice username values. The
default prefixes are regex-safe, but a customized prefix containing
regex metacharacters would produce a wrong (too broad or invalid)
appservice user namespace.
Related to the registration regex discussion in #5096.

The playbook-shipped welcome.html hardcoded #2e2f32 for the headline and
welcome text, which is nearly invisible on the dark background Element
renders when the dark theme is active. Element Web's default

switch the text to Element's dark-theme text color (#ebeef2) under a

The wildcard certificate examples attached tls.domains labels to a
router named matrix-synapse-federation-api, but the Synapse role

and the certificate configuration silently did not apply.

Caddy evaluates directives according to its own fixed directive order,

The exporter's wal collector (enabled by default) calls pg_ls_waldir(),
which Postgres restricts to superusers and members of the pg_monitor
role. The exporter user is created as a plain managed-database user, so
scraping logged "permission denied for function pg_ls_waldir" on every
run.
Grant pg_monitor via the managed database's additional_sql_queries,
which the Postgres role applies both on initial creation and on
subsequent runs, covering existing installations too.

The upstream Synapse Grafana dashboard uses `{{job}}-{{index}}` in its
legends to tell workers apart, but the worker scrape configs only set
instance, worker_id, job and app labels. Without an index label, the
dashboard legends collapsed and workers could not be distinguished.
Derive the index label from the worker id (its per-type index is the
first number in the id, e.g. federation-sender-1, stream-writer-2-events),
matching the index label already set on the main process target.

Element Desktop (Electron) loads the location-sharing map style from a
`vector://vector` origin, so fetching map_style.json from the Element
domain is a cross-origin request. Without an Access-Control-Allow-Origin
header, the request is blocked and maps fail to load with "This homeserver
is not configured correctly to display maps".
Add a dedicated Traefik router for map_style.json that attaches an
Access-Control-Allow-Origin header (configurable via
matrix_client_element_location_sharing_map_style_access_control_allow_origin,
defaulting to `*`). It is only defined when location sharing is enabled.
