BoltAI 2.18.5

Build 97This update improves how chat history and attachments are sent to the model.

Improved

• Improved how chat history is sent to the model in long chats.
• Chat Context now defaults to the last 20 message pairs instead of 8. Chats, projects and agents with their own setting keep it.
• In the Inspector, settings that come from a project, an agent or your defaults are now shown read-only. Click Edit… to customize the chat or change the settings where they come from.
• Long chats that send all messages now show a notice above the composer, with an option to send only the last 20 pairs.
• Large images are scaled down to fit provider limits when sent, in their original format. The attached file isn't changed.

Fixed

• Fixed Chat Context applying only to the first request when the model uses tools. Later steps sent the full chat.
• Fixed attachments the model can't read being dropped silently or sent as files the provider rejects. The model is now told which file it couldn't read.
• Fixed an image that couldn't be loaded being left out of your message. The send now stops and tells you.
• Fixed spreadsheet attachments reaching the model without the values Excel shows, such as dates and percentages.
• Fixed RTF attachments being sent as RTF markup instead of text.
• Fixed Quick Compose and the Instant Chat Bar dropping your default system prompt and parameters when you picked a model.
• Fixed agents set to "Use Default" Chat Context ignoring your account's Chat Context.
• Fixed a reply you stopped being sent back to the model with its unfinished reasoning. Replies cut off by the output limit keep their reasoning.
• Fixed Save & Regenerate on an earlier message regenerating the wrong reply while the chat showed an error.
