- fossology/fossology#3916: Skip reserved email domains in copyright scans
Fixed the copyright agent's email regex so example.com, .test and .invalid addresses are skipped instead of reported with the last letter cut off.
C++RegexTesting - fossology/fossology#3903: Fix CycloneDX 1.7 schema validation
Made the CycloneDX 1.7 SBOM export schema-valid by replacing the removed vendor field and writing non-SPDX licenses as expressions.
PHPSBOM - fossology/fossology#3902: Preserve license type on import
Stopped license imports without a type column from resetting every matched license to a misspelled 'Permisssive' type, with unit test coverage.

- supabase/realtime#2379: Pick broadcast payload type from Content-Type
Made the single broadcast endpoint choose JSON or binary from the Content-Type header, so JSON bodies with a _binary key or non-object payloads are no longer mangled.
ElixirPhoenix - supabase/realtime#2345: Contain serializer encode errors
Stopped one oversized broadcast event from crashing the shared GenRpcPubSub worker by containing serializer errors in the message dispatcher.
ElixirReliability - supabase/realtime#2343: Reject non-string presence keys
Validated presence keys as strings so a single bad join can no longer crash the Presence shard shared across tenants.
ElixirPhoenix - supabase/realtime#2306: Fix flaky Presence & Replication tests
Fixed 6 flaky integration tests across Presence rate limiting, untracking, and replication slot handling.
ElixirTesting - supabase/realtime#2283: Fix flaky CDC, metrics & tenant tests
Fixed flaky cdc_rls, metrics_pusher and tenant_controller tests, including an assertion that compared a list to an integer and never checked anything.
ElixirTesting - supabase/realtime#2231: Fix WAL sender test flakes
Fixed max_wal_senders test flakes caused by missing public.test table in Realtime.
ElixirPostgreSQLTesting - supabase/realtime#2228: Consolidate extension tests
Refactored and consolidated extension tests into one canonical location mirroring lib/.
ElixirTesting - supabase/realtime#2222: Suppress Ranch connection logs
Added tests to verify that Ranch killed connection logs are properly suppressed in the tracker.
ElixirRanch - supabase/realtime#2174: Fix emoji slicing in fuzzy search
Prevented emoji surrogate pair slicing bugs in the Realtime inspector's fuzzy search feature.
ElixirSearch - supabase/realtime#2167: Fix Ranch charlist log filter
Fixed character list handling in the Ranch log filter to prevent logging errors.
ElixirLogging - supabase/supabase#50306: Proxy .well-known auth route
Proxied /.well-known/* and /pg/* routes to the API gateway in Caddy/Nginx configs to fix 404s.
DockerNginxCaddy - supabase/supabase#46021: Secure Realtime encryption key
Moved hardcoded Realtime DB_ENC_KEY to a configurable .env variable for self-hosted instances.

Elixir
elixir-lang/elixir
- elixir-lang/elixir#16004: Keep parens on anonymous calls with do-end blocks
Fixed the formatter dropping parens on anonymous function calls with do-end blocks, which turned valid code into unparseable output and also affected Macro.to_string/1.
ElixirFormatter - elixir-lang/elixir#16001: Stable formatting for comments in tuple arguments
Restored the comment check the formatter uses when a tuple or bitstring is the last call argument, so mix format gives stable output on the first pass.
ElixirFormatter - elixir-lang/elixir#15999: Stable formatting for comments after operators
Made a comment before an operator's right operand force a line break, so mix format no longer changes its output on a second run.
