The labeler only listened for issues.opened, so it judged a title exactly
once. Reporters who omit the prefix are asked by the triage bot to add one,
and the title they then fix is never looked at again, leaving a genuine bug
report unlabelled until somebody notices it by hand.
It now also runs on issues.edited. Body only edits return immediately, so
the extra runs are limited to titles actually changing, and a bug label a
maintainer has already removed is not restored: on an edit the issue events
are checked for a previous removal first. The opened path is unchanged and
makes no additional API call.
The title pattern also required a delimiter after the bracket, so the
bracketed form the comment advertises, "[Bug] something is broken", never
matched unless it happened to be written "[Bug]: something is broken".
Both forms match now, while "[bug/perf]" keeps matching and titles that
merely mention the word, such as "[UI Bug]" or "fixed a typo", still do not.
A message sent while an attachment is still uploading is held in the chat
queue until the file settles. For files that release works, because the
message input calls onUpdate once the upload completes, which refreshes the
queued entry and asks the queue to run.
Attaching a URL takes a different path. uploadWeb sets the item to uploaded
but calls neither onUpdate nor processNextInQueue, and the queue is
otherwise only revisited when a generation finishes or when the chat is
mounted while idle. In a new chat with nothing generating, none of those
happen, so a message queued behind a URL waits with no event able to
release it until the chat is reloaded.
uploadWeb now asks the queue to run when it is done, the same way the file
path already does.
Logging in through CyberArk Identity dies at the callback with "Unsupported {'app_id'} in header" and the user sees "The email or password provided is incorrect". Any provider that puts a vendor-specific parameter in the ID token header hits this; CAS was already patched by name, CyberArk is the next one.
Authlib 1.7 verifies ID tokens with joserfc, which rejects header parameters it does not recognise. The old fix registered `client_id` so CAS would work, which only ever fixes one provider at a time. This turns off the unknown-header rejection instead, so any private header parameter is ignored rather than fatal. Signature verification, the algorithm allowlist, `crit` handling and value validation of registered headers all still run, so nothing that actually protects the token is relaxed.
Fixes#28062
Since v0.11.0 shipped aiodns, aiohttp silently switched every outbound request from the OS resolver to c-ares. On some Windows hosts the bundled c-ares 1.34.6 (pycares 5) discovers only 127.0.0.1:53 as nameserver, so every external provider lookup fails (#28013). In Docker the long-lived c-ares channel intermittently stops resolving container names while Docker's embedded DNS keeps answering, which wipes the Ollama model list and fails all in-flight chats with a misleading "Model not found" (#28215).
This restores the pre-0.11 ThreadedResolver (OS resolver) by default and gates the c-ares path behind a new env var, AIOHTTP_CLIENT_ASYNC_DNS_RESOLVER, off by default. The event-loop DNS perf improvement is now opt-in for deployments whose resolver setup is known to work with c-ares, instead of a process-wide side effect of the package being installed.
aiodns is also downgraded and pinned to 3.6.1 (pycares<5), the last release before the broken c-ares 1.34.6 build, so opting in does not hit the Windows regression. The hardcoded AsyncResolver in the Mistral OCR loader now follows the same switch. Simply removing aiodns instead was not an option because opting in would then be impossible, and #28215 showed the Docker failure is c-ares itself, not aiodns 4.x.
Newer OpenAI chat models put metadata on the opening line of a colon fence block, like :::writing{variant="email" id="48173" subject="Short question" recipient="mail@example.com"}. The tokenizer matched that line and discarded it, so every block rendered under the same generic "Writing" heading no matter what it contained.
The opening line is now parsed into an attributes map on the token and the header uses it: the subject becomes the title, the recipient follows it and the full string is reachable on hover when the row is too narrow for it. Blocks without metadata render exactly as before, and the other fence types get the parsed attributes for free.
Attributes are read only from inside the {...} braces, not from the whole opening line. Scanning the whole line turned ordinary prose containing key="value" into metadata, and it backtracked quadratically: a 40k character opening line took 586ms to parse, and that runs again on every re-lex while the message streams. Anchored to the braces it is 0.0ms.
Nothing here turns the recipient into a link or a send action. That metadata is model output and can be steered by whatever is in the context, so a prefilled mail action is a separate decision rather than a side effect of parsing.
Adding a model ID that was already on the list in the connection settings modal simply appended it again, so the same model could sit in the whitelist any number of times. The arena model modal had the same flaw, its dropdown kept offering models that were already selected.
The connection modal now rejects a duplicate with a toast and trims the input first; surrounding whitespace renders invisibly in the list, so an untrimmed ID would slip past the duplicate check and still show up as a visually identical row. The arena modal instead filters already-added models out of the dropdown, matching the existing model selector in the admin settings, so a duplicate can no longer be picked at all. Both modals also drop duplicates when loading a stored list, so configs that already contain them are cleaned on their next save.
Until such a config is re-saved, one residual effect of old data remains: a duplicated ID in an arena model's stored list keeps double weight in the random model draw. New duplicates can no longer be created through the UI.
Fixes#28249
Fetching a URL and saving it were reported as one thing. Everything from
reading the URL to writing the vector database sat inside a single try,
whose handler blamed the knowledge base, so a page that could not be
fetched, parsed or resolved was reported as a knowledge base error even
though nothing had reached the knowledge base yet. Reading the URL now has
its own handler that names the URL, and the knowledge base message is left
to the step that actually touches it.
When YouTube refused a transcript the reason was discarded earlier still:
the loader caught the error, logged it, and returned an empty document
list, so the empty result failed downstream and even the salvageable
explanation was gone before a message was produced. The loader now raises
YoutubeTranscriptError carrying a readable reason, mapped from the
transcript library's own exception types. Blocked requests mention that a
proxy can be configured, and disabled, age restricted, unavailable and
missing language cases each say what actually happened.
URLs that attach successfully are unaffected.
Chat creation and chat moves each carried their own copy of the same folder_id validation, resolving the folder and checking ownership and shared write access in slightly different ways. Both now call a single has_folder_write_access helper, which the chat-completions creation path uses as well, so ownership, inherited write grants and nonexistent or malformed ids behave identically everywhere a chat folder_id is set. The owner case also costs one query fewer than before.
JSONField serializes with JSONCodec, but columns declared as SQLAlchemy's own JSON
type go through the engine's serializer instead, and no engine set one. That left
Chat.chat - the largest blob the app stores - on stdlib json.dumps/loads no matter
what ENABLE_ORJSON was set to, while the rest of the app used the codec. SQLAlchemy
invokes it once per write and once per read, so every chat read and write paid a
full stdlib pass over the whole conversation on top of whatever the caller did.
Both engine constructors are now wrapped so the codec is wired in by default and
cannot be missed by a call site that forgets it; an explicit json_serializer still
wins. The 10 create_engine/create_async_engine calls in this module go through the
wrappers. Vector-store engines (pgvector, mariadb, opengauss) are separate databases
and are left alone.
Serializing and deserializing chat-shaped blobs, median of 11 runs:
| chat blob | write | read |
| --- | --- | --- |
| 600 msgs (2.8 MB) | 10.1 -> 1.7 ms | 8.4 -> 3.7 ms |
| 3000 msgs (14.2 MB) | 51.9 -> 8.0 ms | 48.5 -> 27.8 ms |
| 6000 msgs (28.5 MB) | 105.9 -> 29.5 ms | 112.7 -> 80.5 ms |
With ENABLE_ORJSON off JSONCodec is stdlib json, so this is a no-op until the flag
is set - the change cannot regress a default deployment.
With it on, a round-trip probe through a native JSON column returns objects equal to
the stdlib ones on all 12 shapes tried: ASCII, CJK, emoji, astral-plane, unicode
keys, null bytes, lone surrogates, floats, ints above 2**63 and 2**64, line
separators, empty and deeply nested. Stored text changes for non-ASCII, which is
written as raw UTF-8 rather than backslash-uXXXX escapes and is correspondingly
smaller. Nothing queries that text by escape except two Postgres safety filters in
chats.py, and both still hold: a null byte is escaped identically by both codecs,
and the title filter reads a text column rather than JSON. The ->> and json_extract
searches decode the string before matching, so escaping cannot reach them.
Two differences are inherent to JSONCodec and already apply to every JSONField
column: ints beyond 2**64-1 come back as float, and NaN/Infinity serialize to null
rather than the bare literals stdlib emits - the latter being invalid JSON that a
Postgres json column rejects today. Neither shape occurs in chat blobs. Alembic
builds its own engine and stays on stdlib, which is fine in both directions since
each codec reads the other's output.
