Affected places: `FullChat.chat_type`, `BasicChat.chat_type`, `ChatListItemFetchResult::ChatListItem.chat_type`, `Event:: SecurejoinInviterProgress.chat_type` and `MessageSearchResult.chat_type` ([#7285](https://github.com/chatmail/core/pull/7285))
+
+### Features / Changes

+- Do not return an error from `receive_imf` if we fail to add a member because we are not in chat.
+- Do not add QR inviter to groups immediately.
+- Do not ignore I/O errors in `BlobObject::store_from_base64`.
+
+### Miscellaneous Tasks
+
+- Rustfmt.
+
+### Refactor
+
+- imap: Move resync request from Context to Imap.

+# @deltachat/jsonrpc-client
+
+This package is a client for the jsonrpc server.
+
+> If you are looking for the functions in the documentation, they are under [`RawClient`](https://js.jsonrpc.delta.chat/classes/RawClient.html).
+
+### Important Terms
+
+- [chat mail core (formerly delta chat core)](https://github.com/deltachat/deltachat-core-rust/) is heart of all Delta Chat clients. Handels all the heavy lifting (email, encryption, ...) and provides an easy api for bots and clients (`getChatlist`, `getChat`, `getContact`, ...).
+- [jsonrpc](https://www.jsonrpc.org/specification) is a JSON based protocol
+  for applications to speak to each other by [remote procedure calls](https://en.wikipedia.org/wiki/Remote_procedure_call) (short RPC),
+  which basically means that the client can call methods on the server by sending a JSON messages.
+- [`deltachat-rpc-server`](https://github.com/deltachat/deltachat-core-rust/tree/main/deltachat-rpc-server) provides the jsonrpc api over stdio (stdin/stdout)
+- [`@deltachat/stdio-rpc-server`](https://www.npmjs.com/package/@deltachat/stdio-rpc-server) is an easy way to install `deltachat-rpc-server` from npm and use it from nodejs.
+
+#### Transport
+
+You need to connect this client to an instance of chatmail-core via a transport.
+
+For this you can use the `StdioTransport`, which you can use by importing `StdioDeltaChat`.
+
+You can also make your own transport, for example deltachat desktop uses a custom transport that sends the json messages over electron ipc.
+Just implement your transport based on the `Transport` interface - look at how the [stdio transport is implemented](https://github.com/deltachat/deltachat-core-rust/blob/7121675d226e69fd85d0194d4b9c4442e4dd8299/deltachat-jsonrpc/typescript/src/client.ts#L113) for an example, it's not hard.
+
+The other transports that exist (but note that those are not standalone, they list here only serves as reference on how to implement those.):
+
+- Electron IPC (from Delta Chat Desktop)

+## Usage
+
+> The **minimum** nodejs version for `@deltachat/stdio-rpc-server` is `16`
+
+```
+npm i @deltachat/stdio-rpc-server @deltachat/jsonrpc-client
+```
+
+```js
+import { startDeltaChat } from "@deltachat/stdio-rpc-server";
+// Import constants you might need later
+import { C } from "@deltachat/jsonrpc-client";
+
+async function main() {
+  const dc = await startDeltaChat("deltachat-data");
+  console.log(await dc.rpc.getSystemInfo());
+  dc.close();
+}
+main();
+```
+
+For a more complete example refer to <https://github.com/deltachat-bot/echo/tree/master/nodejs_stdio_jsonrpc>.
+
+### Listening for events
+
+```ts
+dc.on("Info", (accountId, { msg }) =>
+  console.info(accountId, "[core:info]", msg),
+);
+// Or get an event emitter for only one account
+const emitter = dc.getContextEvents(accountId);
+emitter.on("IncomingMsg", async ({ chatId, msgId }) => {
+  const message = await dc.rpc.getMessage(accountId, msgId);
+  console.log("got message in chat " + chatId + " : ", message.text);
+});
+```
+
+### Getting Started
+
+This section describes how to handle the Delta Chat core library over the jsonrpc bindings.
+For general information about Delta Chat itself,
+see <https://delta.chat> and <https://github.com/deltachat>.
+
+Let's start.
+
+First of all, you have to start the deltachat-rpc-server process.
+
+```js
+import { startDeltaChat } from "@deltachat/stdio-rpc-server";
+const dc = await startDeltaChat("deltachat-data");
+```
+
+Then we have to create an Account (also called Context or profile) that is bound to a database.
+The database is a normal SQLite file with a "blob directory" beside it.
+But these details are handled by deltachat's account manager.
+So you just have to tell the account manager to create a new account:
+
+```js
+const accountId = await dc.rpc.addAccount();
+```
+
+After that, register event listeners so you can see what core is doing:
+Intenally `@deltachat/jsonrpc-client` implments a loop that waits for new events and then emits them to javascript land.
+
+```js
+dc.on("Info", (accountId, { msg }) =>
+  console.info(accountId, "[core:info]", msg),
+);
+```
+
+Now you can **configure the account:**
+
+```js
+// use some real test credentials here
+await dc.rpc.setConfig(accountId, "addr", "alice@example.org");
+await dc.rpc.setConfig(accountId, "mail_pw", "***");
+// you can also set multiple config options in one call
+await dc.rpc.batchSetConfig(accountId, {
+  addr: "alice@example.org",
+  mail_pw: "***",
+});
+
+// after setting the credentials attempt to login
+await dc.rpc.configure(accountId);
+```
+
+`configure()` returns a promise that is rejected on error (with await is is thrown).
+The configuration itself may take a while. You can monitor it's progress like this:
+
+```js
+dc.on("ConfigureProgress", (accountId, { progress, comment }) => {
+  console.log(accountId, "ConfigureProgress", progress, comment);
+});
+// make sure to register this event handler before calling `dc.rpc.configure()`
+```
+
+The configuration result is saved in the database.
+On subsequent starts it is not needed to call `dc.rpc.configure(accountId)`
+(you can check this using `dc.rpc.isConfigured(accountId)`).
+
+On a successfully configuration delta chat core automatically connects to the server, however subsequent starts you **need to do that manually** by calling `dc.rpc.startIo(accountId)` or `dc.rpc.startIoForAllAccounts()`.
+
+```js
+if (!(await dc.rpc.isConfigured(accountId))) {
+  // use some real test credentials here
+  await dc.rpc.batchSetConfig(accountId, {
+    addr: "alice@example.org",
+    mail_pw: "***",
+  });
+  await dc.rpc.configure(accountId);
+} else {
+  await dc.rpc.startIo(accountId);
+}
+```
+
+Now you can **send the first message:**
+
+```js
+const contactId = await dc.rpc.createContact(
+  accountId,
+  "bob@example.org",
+  null /* optional name */,
+);
+const chatId = await dc.rpc.createChatByContactId(accountId, contactId);
+
+await dc.rpc.miscSendTextMessage(
+  accountId,
+  chatId,
+  "Hi, here is my first message!",
+);
+```
+
+`dc.rpc.miscSendTextMessage()` returns immediately;
+the sending itself is done in the background.
+If you check the testing address (bob),
+you should receive a normal e-mail.
+Answer this e-mail in any e-mail program with "Got it!",
+and the IO you started above will **receive the message**.
+
+You can then **list all messages** of a chat as follows:
+
+```js
+let i = 0;
+for (const msgId of await exp.rpc.getMessageIds(120, 12, false, false)) {
+  i++;
+  console.log(`Message: ${i}`, (await dc.rpc.getMessage(120, msgId)).text);
+}
+```
+
+This will output the following two lines:
+
+```
+Message 1: Hi, here is my first message!
+Message 2: Got it!
+```
+
+<!-- TODO: ### Clean shutdown? - seems to be more advanced to call async functions on exit, also is this needed in this usecase? -->

+Also your system probably needs more than 4GB RAM to compile core, alternatively your could try to build the debug build, which might take less RAM to build.

+1. clone the core repo, right next to your project folder: `git clone git@github.com:deltachat/deltachat-core-rust.git`
+2. go into your core checkout and run `git pull` and `git checkout <version>` to point it to the correct version (needs to be the same version the `@deltachat/jsonrpc-client` package has)
+3. run `cargo build --release --package deltachat-rpc-server --bin deltachat-rpc-server`
+
+Then you have 2 options:
+
+### point to deltachat-rpc-server via direct path:
+
+```sh
+# start your app with the DELTA_CHAT_RPC_SERVER env var
+DELTA_CHAT_RPC_SERVER="../deltachat-core-rust/target/release/deltachat-rpc-server" node myapp.js
+```
+
+### install deltachat-rpc-server in your $PATH:
+
+```sh
+# use this to install to ~/.cargo/bin
+cargo install --release --package deltachat-rpc-server --bin deltachat-rpc-server
+# or manually move deltachat-core-rust/target/release/deltachat-rpc-server
+# to a location that is included in your $PATH Environment variable.
+```
+
+And make sure to enable the `takeVersionFromPATH` option:
+```js
+startDeltaChat("data-dir", { takeVersionFromPATH: true });
+```

+As an extension to `Autocrypt-Gossip` header,
