A non-string metadata generation_name reached the OTLP encoder and took the whole batch down; it is now exported as its text and the exporter drops only the span the encoder rejects. LANGFUSE_RELEASE falls back to the deploy platform's commit variable again, the export deadline is back to the v2 default of 20 s and LANGFUSE_MAX_RETRIES sizes the retry ladder. An expired prompt is served at once while one background thread refreshes it, a re-acquired export channel cancels the pending retire timer, and flush reports delivery rather than a drained queue

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

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

The callback's TracerProvider now sets its sampler, span limits and id generator explicitly so unrelated OTEL_* variables no longer change what Langfuse receives, and trace metadata is written once on the trace instead of folded into the generation, which kept input and output under the attribute cap. Spans are emitted under the langfuse-sdk scope so Langfuse renders them natively, the batch processor queues 100k spans and honors LANGFUSE_FLUSH_AT, and the proxy shutdown flush runs off the event loop with a 10s deadline and logs a miss.
Prompts, auth_check and the project id now go through LangfuseAPI directly with a litellm-owned TTL cache, so no Langfuse() client is built and a host application's client on the same public key is left alone. Dead attributes, the unreachable exporter branch and the export list are cleaned up, and the client-budget eviction behavior is documented.

The httpx.Response built for a Rust upstream failure had no request attached,
so constructing openai.AuthenticationError raised RuntimeError inside the
exception mapper and every bad-key OCR call surfaced as APIConnectionError 500
instead of AuthenticationError 401 (the Python path already returned 401)

Authorization and pricing read the first model and language query value, but the raw query was forwarded, so Deepgram (which honours the last repeated value) could be sent a model the key was never allowed. Later duplicates of those two keys are now dropped before the upstream URL is built

A caller could pick a model with only a pre-recorded registry row, or no row at all, and the session would be billed at the pre-recorded rate or logged at zero cost, so budgets did not apply. The route now closes the WebSocket with 1008 before dialing Deepgram unless deepgram/streaming/<model> (or the -multilingual row for language=multi) is an exact registry hit, and the logging handler applies the same check so a registry change under a live session records the duration with no cost instead of a substitute rate
Regression tests cover the route refusal, an operator-supplied streaming row for another model being accepted, and the handler never substituting the pre-recorded rate

A mixed /team/member_add list that names an existing member used to run
add_new_member for them, which created or cloned a budget that the empty
upsert update branch never linked to their membership row. Filter the
requested members against the freshly locked roster first so budgets and
membership rows are only written for members who are actually new

Replaces the per team advisory lock and Pydantic roster parse in the spend flush
with a single INSERT ... ON CONFLICT statement that checks the stored roster in
SQL, so malformed roster JSON cannot fail the whole flush and large batches no
longer issue two queries per team inside the fixed transaction deadline

Take the team advisory lock in the spend flush transaction and read the roster
through it, so a delayed flush after /team/member_delete cannot recreate the
deleted LiteLLM_TeamMembership row. TEAM_ADVISORY_LOCK_SQL moves to
team_repository so the spend writer can import it without a circular import

add_new_member only wrote a LiteLLM_TeamMembership row when a budget id
resolved, and the spend writer used update_many so a missing row failed
silently. Members without a budget therefore never accrued per-member spend.
The membership row is now always upserted (budget_id NULL when no budget
applies) and the spend write is an upsert so members added before this fix
start accruing on their next request.
