Matches the earlier Python -> Go rewrites of the other mautrix-* bridges. Related to: - https://github.com/mautrix/telegram/releases/tag/v0.2604.0 - https://mau.fi/blog/2026-04-mautrix-release/ The bridge is now a Go binary with upstream-handled automatic database and config migration on first start, so in-place upgrades on Postgres should Just Work for users on the defaults. The lottieconverter sidecar container is gone (bundled upstream), and the public web-based login endpoint is gone (login happens inside Matrix now). Upstream v0.2604.0 has a known bug in the legacy SQLite migration that can corrupt data. The role detects legacy Python-bridge SQLite databases (via the `telethon_sessions` table signature) and refuses to upgrade, pointing users to switch to Postgres (playbook-managed pgloader migration) or wait for the next upstream release. The guard is isolated in its own `validate_config_sqlite_legacy_migration_bug.yml` so it can be deleted cleanly once upstream fixes the bug. Removed variables (all caught by the deprecation check in `validate_config.yml` with actionable rename/removal hints): the entire `_hostname` / `_path_prefix` / `_scheme` / `_public_endpoint` / `_appservice_public_*` / `_container_labels_public_endpoint_*` / `_container_http_host_bind_port` family (web login endpoint is gone); `_bot_token` (old-style relaybot is gone, use the common bridgev2 relay mode); `_filter_mode` (dropped upstream); `_bridge_login_shared_secret_map*` (use Appservice Double Puppet); `_username_template`, `_alias_template`, `_displayname_template` (templates moved under `network:`, new Go-template syntax, exposed via `_network_displayname_template`); all `_lottieconverter_*` variables; `_appservice_database` (renamed to `_appservice_database_uri`). Added playbook-time validation that catches legacy permission values (`relaybot`, `puppeting`, `full`) in the fully-merged config (so overrides via `matrix_mautrix_telegram_configuration_extension_yaml` are caught too), with a mapping hint in the error message. Other notes: - The legacy sqlite->postgres relocation of `{base_path}/mautrix-telegram.db` to `{data_path}/mautrix-telegram.db` now happens BEFORE the pgloader migration step, so users who flip to Postgres as part of this upgrade get their data imported correctly. - The Ketesa managed-user regex for the telegram namespace is updated to match both regular IDs and the new `channel-<id>` form used by bridgev2. - `matrix_playbook_migration_expected_version` bumped to v2026.04.24.0, with a new breaking-change entry pointing at the CHANGELOG section.
