#Onboarding checklist for new users

New users are now presented with an onboarding checklist that helps them get into the app and get their contacts connected.

#Profile menu “Lock” option

The profile menu now has a “Lock” option that immediately requires your PIN code to re-enter the app (if you have a PIN code).

#Increase chat character limit

The chat character limit (per message) has been increased from 2,000 characters to 4,000 characters.

#Pause downloads if disk is full

We’ve had reports of some smaller devices filling up their disk and then crashing if they are being used in 2-way / full sync mode. Now downloads are paused if the disk has filled up, and the user is warned.

#Mermaid diagrams in markdown

Mermaid diagrams are now supported in markdown files.

To enter a mermaid diagram, you must use “Source” mode and start it with:

```mermaid

and end with

```

E.g. you can render things like this:

#Fix: Add profile button

The “Add profile” button was broken - this has been fixed.

#Fix: Invite “Join” button turns grey

Sometimes, when clicking “Join” from an invite, the button would just turn grey and nothing would happen. This edge casey issue was due to blockchain communication disruptions, and now gives the user some feedback when they are on an unstable network.

#Fix: Sync About page faster when joining

The About page sync is now prioritized when joining a Zone

#Fix: Some chat messages were silently dropped

Chat messages with `{:…}` text in them were being silently dropped - they would never be sent and nothing would be shown to the user.

#Fix: Slow disk application startup

Devices with a slow disk now load Diode Collab faster
