- A redirect followed for a custom base URL also drops the key headers of
providers that do not use Authorization (x-api-key, x-goog-api-key,
api-key) when it goes to another origin.
- A second Enter or click while a message is being prepared (attachments
read, diagram exported) no longer sends it twice.
- The admin Test on the deployment's own endpoints (EdgeOne, the server's
keyless Ollama, an address on the server's network) counts toward the
quota like a chat; the chat and the Test share one rule for it. The
Test of an Azure entry set up by AZURE_RESOURCE_NAME only goes where chat
goes.
- EdgeOne's function is called at the site root again, as on main: EdgeOne
serves edge functions there, outside Next's base path.
- MCP History: the state before a write is kept unless the browser saved
no change of the user's since the last server write (draw.io's sync copy
of it adds no entry), and the dedupe compares the exact text again, so a
change of page size or other settings only is its own version.
- MCP: an edit keeps untouched labels as draw.io shows them (a literal line
break in an attribute is a space); a new document of empty pages the
user named is auto-saved; load_diagram reads only regular files, so a
pipe cannot hold up the other write tools; the preview does not load
back its own push still on its way (an undo made meanwhile is saved).
- Two overlapping saves of a new chat no longer reload the canvas from the
older copy.
- At most three screenshot checks per user turn, passed or failed, as
documented.
- Desktop: the main window navigates only within the app (draw.io stays in
its frame); a presets file that is not JSON and cannot be moved aside is
not overwritten.
- A last self-closing cell with a raw "<" in a value is not taken for cut
off output.
- README: Material Design shapes load their icons from fonts.gstatic.com.
- A redirect followed for a custom base URL (quota on) no longer carries
the user's key or cookies to another origin, as fetch itself does, and
a private address may redirect to another private one (already counted).
- The admin Test of an Ollama or Vertex AI entry without a URL goes where
chat sends that entry's key: the environment's own URL variable, for
Ollama else the local default. The Test of an Ollama Cloud key without
a URL went to the cloud while chat went to local Ollama.
- Chat saves: each save notes the chat on screen and the order of the
reads before reading its data. A save read before switching chats no
longer writes into the chat switched to, and a copy that waited for its
thumbnail no longer replaces a newer one.
- "Continue without saving" keeps its button when a later auto-save fails,
and goes away when a new message is sent.
- A screenshot check that was waiting for its image when the user pressed
Stop stays skipped after the next message.
- MCP History: draw.io's own copy of a diagram (after get_diagram) no
longer adds an entry without a picture; a change of background is still
its own version. The tab ignores an edit's answer that arrives after a
newer AI write loaded.
- Desktop: a deleted preset is not brought back by a failed switch, and a
request naming no preset does not stop a rollback. An origin keeping
an access code counts as having settings.
- .env: a quoted value ending in a backslash ("C:\dir\") is read as dotenv
reads it.
- The tool card no longer crashes on an id that does not turn into text;
an older Test's success timer no longer ends a newer Test's spinner.
- Tests that passed without their fix now check it.
Chats:
- New Chat right after an answer saves that chat once. Saves run one at
a time and read the chat on screen when their turn comes; a save
scheduled for a chat that is no longer on screen is dropped. A chat
whose id was still on its way to the URL no longer comes back after
New Chat (the next answer went into it).
- Crossing the 768 px breakpoint keeps the chat panel: a streaming answer,
unsaved messages and attachments stay. The panel gets the sizes of each
side, and a panel collapsed on desktop opens on mobile.
- The chat's export waits for its own reply: an edit's history export
still on its way no longer answers it with the older diagram, and two
file saves at once no longer swap results.
- A second edit in one answer is previewed on the first edit's result.
- Stop also ends a running screenshot check; a chat that cannot be saved
(storage full) can be left with "Continue without saving".
- Small diagrams with shapes count as diagrams; the tool card no longer
crashes on malformed operations.
Quota and providers:
- Requests that reach the server's own endpoints count toward the quota:
EdgeOne (always its own endpoint now), a private base URL whatever key
header is sent, keyless Ollama without a URL. With the quota on, a
redirect is followed only to a public address. The output cap applies
to these requests too.
- Stop records the tokens of the steps that finished; the screenshot check
counts its tokens without counting a request.
- EdgeOne configured only by AI_PROVIDER works, also in the admin Test,
which forwards the access code. Azure set up only in the admin panel
works in chat. The Test sends a Bedrock session token.
- The admin panel's Test of an entry without a URL uses the server's URL
as the server does (no private address check for it); the admin panel
no longer writes an Ollama URL.
MCP server:
- Write tools and start_session run one at a time, so two at once never
drop each other's change; a cancelled call waiting its turn is skipped.
get_diagram and export_diagram keep the session they started with.
- Export to .drawio first gets the user's latest edits from the browser.
- History thumbnails: one that arrives after the next AI write is
dropped; a sync reply keeps the image; a version that changed only page
settings is its own entry.
- A diagram over the 10 MB limit is saved without its image, or the user
is told to download it (the server now answers 413 instead of cutting
the connection).
- Labels holding text like id='1' or parent='1' are no longer read as
attributes (a layer or a parent was deleted). A broken bare
<mxGraphModel> file is refused.
- After a sync reply the tab no longer sends its autosave copy again.
Desktop and files:
- A newer switch of the same preset is not rolled back by an older one
that failed. .env values with escaped quotes are read whole.
- MCP saved files: a file that could not be read stays protected while a
folder without permission hides it, and is saved again once deleted.
- The desktop app reports "no chats" only when the count was read and no
model settings are stored.
MCP preview after the server lost a session (it expired, or the MCP
process restarted):
- Every server state has an id, made when the state is created. The tab
notices a new id even when the version numbers happen to match, and
every push names the state it was based on, so one based on a lost state
is refused, also when it comes before the tab's first poll (the server
recovers the saved file first).
- The tab keeps the newest canvas XML, saved or not. When the server knows
nothing (no file) or exactly what the tab last saved, the canvas wins and
is saved, so edits made while the server was down are kept. Otherwise
the server's diagram (an AI write the tab missed, a cleared document
that was saved) is shown and the tab's copy goes to History.
- Late answers to an old state's push or poll are dropped; a failed push
says the server is unreachable; Download as .drawio saves the canvas.
Settings and server:
- Saved providers this version does not know stay in storage with their
keys, and sending no longer trips over them.
- The desktop "Ollama (Local)" preset with a key goes to local Ollama
again; a server model's Ollama URL variable is read; the admin panel
writes Ollama Cloud's URL for a key without one.
- Provider error texts show again in the desktop app and for EdgeOne.
- .env: a quoted value followed by a comment ending in a quote is read as
dotenv reads it; unquoted values are unchanged.
- Desktop app: the next launch opens the port where a chat was last
saved; a launch elsewhere that saves nothing does not move it, and a
page with no chats lets the next launch try the other port once.
- The Test button no longer stays busy after another tab changed the key.
- A completed append_diagram is no longer undone by an earlier failed
edit's preview; a file read once in vain is saved again once it is read
or gone.
From the first batch's review:
- The admin panel's Test of an entry without a URL now tests the server's
<P>_BASE_URL, where chat sends the entry's key; chat is unchanged (the
first fix rerouted working setups).
- The model list ends downloads that are too large, accepts answers
without a body, and keeps the "redirects are not allowed" explanation.
- A test covers the preview's History rendering.
- Bedrock: a user's AWS keys no longer go to an endpoint the server sets
in AWS_ENDPOINT_URL_BEDROCK_RUNTIME / AWS_ENDPOINT_URL (read by the
upgraded SDK), and admin panel keys win over AWS_BEARER_TOKEN_BEDROCK,
as the Test button checks them. Checked with Bedrock.
- Ollama: a server key without a base URL (admin panel, OLLAMA_API_KEY)
goes to Ollama Cloud, as env.example says, instead of 127.0.0.1.
- Quota: EdgeOne counts whatever key header comes along, keyless Ollama at
a private address counts, and their provider texts stay in the log.
- An EdgeOne server model (admin panel, ai-models.json) works: the route
checked the raw provider header, which holds the name's slug.
- parse-url ends downloads it does not read (too large, PDF, errors).
- Desktop app: the port follows where the chats are (IndexedDB per
origin) instead of a remembered port, which could hide them for good;
a same-port restart tells the page to refetch the server models; a
failed preset switch no longer undoes a newer choice; a presets file
removed after a failed read can be saved again; .env values quoted from
start to end keep their inner quotes, as dotenv reads them.
Found by the second PR review:
- With AWS_BEARER_TOKEN_BEDROCK set on the server, a request with the
user's AWS keys ran on the server's token: the Bedrock SDK prefers it.
Checked with Bedrock: invalid user keys used to get an answer.
- An OpenAI key with the official URL filled in (the settings form does
that) went to the Responses API. Back to main's rule: a configured base
URL uses Chat Completions.
- A user's Ollama key went to the server's OLLAMA_BASE_URL, for chat and
for the model list. Like every other provider, it goes to the user's
base URL or Ollama Cloud.
- The server's keyless Ollama and EdgeOne were not counted in the quota.
- AI_MODEL models on the server's keys ran on any provider with a server
key, not only on AI_PROVIDER.
- A user's Azure key without a base URL used the server's resource name.
- The admin panel's Test button failed whenever access codes were set.
- DeepSeek's errors in the stream (plain text) were shown as they were,
without a hint and also on the server's keys. Bedrock's throttling in
the stream was not recognised as a rate limit.
- The EdgeOne function accepted text/plain; x=application/json, which
other sites can send without a CORS preflight.
- Desktop app: a launch that found the old port taken for a moment (the
previous version still quitting after an update) remembered the new
port for good. The new port is kept only when Windows reserves the old
one. A failed read of the presets file moved it aside as corrupt, and a
save could then replace the presets. Switching presets on the same port
now reloads the page. The dev launcher no longer misses a preset change
made before or during a restart.
Found by the PR review, each with a test that failed first:
- Quota: any key header skipped it, even one the provider never reads
(x-aws-access-key-id with OpenAI), so a request ran on the server's
key without being counted. The check now runs after the model is
resolved and uses usesServerCredentials. On main already.
- usesServerCredentials read the raw base URL; "/" cleans up to none, so
an Ollama request ran on the server's key past the server-model check.
- SGLang's default 127.0.0.1:8000 only fills the settings form. Chat and
the model list used it as a real address, so the server called its own
machine even with private URLs blocked. Now a base URL is required.
- With a user's OpenAI key and no base URL, the SDK read the server's
OPENAI_BASE_URL. The official endpoint is now passed. On main already.
- The Test button refused nothing on the server's keys (Ollama Cloud),
and a 15 s timeout reported "connected, no tool call".
- The model list for Ollama without a base URL came from ollama.com while
chat went to the server's Ollama.
- Bedrock's "Too many tokens, please wait" counted as context too long.
- On the server's keys the provider's error text stays in the server log;
it can name the server's AWS account, role or internal hosts.
- Desktop app: the preset keys are the user's own (NEXT_AI_DRAWIO_DESKTOP),
so Max Output Tokens can be raised and keyless models in settings work
again. A launch that found the remembered port taken no longer replaces
it, which hid the user's chats and settings for good.
- /api/log-save accepted only drawio, png and svg, so saving as Editable
SVG (xmlsvg) got a 400 and was never recorded in Langfuse
- The default download name and the template export name used the UTC
date, which is the previous day on mornings in East Asia
- Remove the Electron openFile/saveFile IPC handlers, their preload
bindings and types; nothing in the app calls them
- Apply preset env after app ready, so Windows/Linux get decrypted keys
- Never re-encrypt ciphertext; restore env when switching or removing presets
- Block navigation away from the app, open external links in the browser, check IPC senders
- Keep inherited proxy settings, default NO_PROXY for localhost
- Serialize server start/restart, kill stuck processes, follow port changes
- Atomic config writes, keep corrupt files as backups, remember the server port
- Menu and settings window stay in sync; dev script gets the decrypted preset env
- Use app.isPackaged, parse inline .env comments, drop .env files from the bundle
The draw.io iframe registers a window.onbeforeunload handler that returns
a non-empty string whenever its internal editor.modified flag is true.
After the user edits text in a shape, that flag is set and never cleared.
Per Electron BrowserWindow docs, returning a non-void value from any
beforeunload handler in the page tree silently cancels the window close
without showing a dialog. This is what caused the X button (and Cmd+Q)
to do nothing for users who had typed in a shape.
Calling event.preventDefault() in will-prevent-unload tells Electron to
ignore the iframe's beforeunload return value and proceed with the close.
The host app already persists diagrams via autosave + visibilitychange,
so the prompt was unnecessary.
Verified by reproducing the bug, applying the fix, and re-testing.
Bumps biome.json $schema from 2.4.4 to 2.4.14 so the repo schema
matches the version the 'Auto Format' workflow installs via
@biomejs/biome@latest. Also applies the one auto-fix the newer
version produces (export ordering in electron/electron.d.ts).
Fixes the spurious 'This PR has formatting issues' CI failure that
was blocking fork PRs unrelated to formatting.
Added rpm target (x64 + arm64) alongside existing deb and AppImage
targets. No CI changes required since electron-builder handles both
deb and rpm generation under the --linux flag.

Use explicit from/to/filter file sets instead of top-level globs to
avoid a regression in electron-builder 26.8.x where dist-electron
files were not being included in the asar archive.
electron-builder 26.8.x no longer auto-includes package.json when a
custom files array is specified, causing the main entry file to not be
found in the asar archive.
