Sparrow v2.28.1: Smarter Variables & Enhanced History

Release Date: July 29, 2025

Hey Sparrow Trailblazers,

Sparrow v2.28.1 is here with powerful upgrades to your AI workflow! From smarter variable handling across all LLM inputs to a more complete version history view, this update is all about boosting productivity, clarity, and control. Plus, we’ve got exciting news for all users on our 14-day trial plans—keep reading! 👇

🧠 AI LLM Request: Complete Version History Context

No more fragmented history! Now, when you open a past conversation from the AI LLM Version History, Sparrow will auto-load everything you originally configured including:

System Prompt
Model Configurations
Environment Variables
Chat Content (as before)
Everything you need to pick up right where you left off.

🧩 Variables Everywhere: Smarter, Color-Coded, and Fully Supported

Managing prompts and requests just got more dynamic.

✅ Use Environment Variables Anywhere

: You can now insert variables into:

System Prompts
User Prompts
Auth Section
Generate Prompt Inputs
Just type {{variable_name}} like you do elsewhere in Sparrow. The system will pull values from your current environment.

🎨 Color-Coded Variables for Clarity

Existing variables appear in blue
Unknown or missing variables show in red (watch out for typos!)
Variables used in past conversations are also now visible in Version History - highlighted under the timestamp.
It’s power and precision - wrapped in curly braces.

🕒 14-Day Free Trial for All Plans

We’re extending our 14-day full-access trial to existing users too!

🐞 Squashed Bugs:

In Save Response, export intermittently fails without an error message in webapp.
The "Open in Desktop" button occasionally takes a detour.
In certain cases, AI responses may lack consistency, affecting the reliability of results.

⚠️ Known Glitches

Here’s what we’re still refining—because perfection takes time:

Query Explorer and Editor sync issues might play a bit of hide-and-seek in GraphQL.
Swagger YAML link is not supported while adding a Collection for Active Sync.
Sometimes, switching models does not retain the previous logic or context.
File upload for LLMs is currently in beta. You may experience occasional issues with uploading, file preview visibility, or model compatibility.
