AI Engine Pro 2.6.8

* Add: Similar to "Vision", support for "Files". For now, that means you can upload PDF in the chatbot while using Sonnet 3.5. This will be expanded to other models and features in the future.
* Add: Messages Integrity Check. This will help fighting against malicious attempts to modify the system/assistant messages in the chatbot. When a query to the chatbot will be detected as malicious, an entry will be added in the Logs of the Dev Tools (in AI Engine's UI). It's for testing purposes for now, for those who are interested in helping us testing this, and once bulletproof, it will be deployed as an option with kick/ban features.
* Update: Discussions now include the start sentence as well.
* Fix: The WP Cron related to discussions was running way too often (forgot to remove the debug).
* Fix: Encode the data used in chatbot shortcodes to avoid issues with special characters.
* Fix: Support for embeddings models without defined dimensions (hi, Ollama's embed models!).

2.6.7

* Add: Titles for Conversations. Those titles can be edited by the users.
* Add: The user can also delete the conversations.
* Add: Added default icons when Send and Clear texts are empty.
* Add: Resolution support in the chatbot shortcode.
* Add: AI Discussions Block (and there was already a Chatbot Block if you didn't know).
* Add: mwai_form_takeover filter to override the reply for AI Forms.
* Update: Much smoother flow with the Discussions module.
* Update: Nicer icon for microphone.
* Update: Better (earlier as well) handling of default envs and models.
* Update: Re-organized the Anthropic models.
* Fix: Issue with the Clear button (version 2.6.5).
* Fix: The customId issue when using the Chatbot Block.
* Fix: SQL injection issue in the Discussions module (really minor, as only admins could do it).
