KeyExchangeGroup and Tls12CipherSuite parse with FromStr and fail with Unsupported, so a setting rustls cannot honor is a typed error instead of a missing value. The cipher string conversions cannot fail and use From. The rustls ClientConfig is built with TryFrom<&HttpClientConfig>, and the built-in root store is constructed in one expression
litellm-http now builds the rustls config itself, so one route-neutral place covers roots, the client certificate, ALPN, ssl_ecdh_curve and ssl_security_level. A curve picks the single key exchange group. A cipher string restricts the TLS 1.2 suites it names, and entries rustls cannot express, such as @SECLEVEL=1, are logged once and skipped.
user_url_validation and user_url_allowed_hosts are applied by the media fetcher. Document downloads honor the environment proxy whenever provider calls do, keeping the per-hop address check, and stay on the pinned resolver when no proxy applies.
AIOHTTP_SO_KEEPALIVE, AIOHTTP_TCP_KEEPIDLE, AIOHTTP_TCP_KEEPINTVL, AIOHTTP_TCP_KEEPCNT and AIOHTTP_KEEPALIVE_TIMEOUT map onto the client. A client= argument and a live SSLContext are ignored
Python becomes a thin SDK interface over Rust, so a live Python HTTP client has no effect on either route. This puts the Python OCR path back to what main does
Python OCR passes the call timeout per request, so its connect timeout is the call timeout and never the 5s handler default. 10s is what every Rust route uses on main. The media client never uses a proxy, so trust_proxy_env no longer splits its pool key
The proxy attaches its shared aiohttp session to every request as shared_session, so declining on it sent every proxy OCR call to Python, which never uses that session for OCR. aclient_session is a litellm global and never a call argument, so that check could not match. The proxy-shaped lifecycle test now asserts the call was served by Rust
Generation spans now end in a finally block so a bad guardrail or provider entry cannot strand the trace. The logger acquires its export channel and REST client before counting a client slot and releases the channel synchronously if the REST client fails to build, so retries after a bad config do not exhaust the budget. LANGFUSE_TIMEOUT accepts decimals for the REST client like it already did for OTLP export. The prompt cache keys on (name, version, label) so a missing label and the literal label None stay apart

litellm.user_url_validation and litellm.user_url_allowed_hosts are only implemented by the Python document fetcher, so an allowlisted internal document was rejected by the Rust route's network policy. The bridge now declines when either is changed from its default
Adds a projects entry to the team_admin_editable_team_fields setting. When set, team admins (legacy admins list or members_with_roles role admin) can call /project/new and /project/update for the teams they administer. The two routes join self_managed_routes so the endpoint check runs instead of the route gate's blanket 401. /project/delete stays proxy admin only

An installed v2 SDK used to fail inside the langfuse_sdk import and surface as "Langfuse not installed"; the version check now runs first so v2 users get the upgrade message, and only PackageNotFoundError means the package is missing
Export channels are now leased per credential set: acquire adds a holder, LangFuseLogger.stop (called by DynamicLoggingCache on expiry) releases one, and a channel with no holders is flushed and shut down after a 60 s grace, so rotating key or team credentials no longer grows one batch thread per credential set for the life of the process

Python's aiohttp transport reads HTTP(S)_PROXY on every request unless disable_aiohttp_trust_env is set, so the Rust clients now do the same instead of requiring aiohttp_trust_env. Transport error messages include reqwest's source chain, so a rejected certificate or refused connection is no longer reported as just 'error sending request'
