📝 What Was Modified

Describe EXACTLY what changed from learner perspective:

File 1: Instructions/Labs/Lab-2-Understanding-Project.md

Old behavior / text:

Line 80 previously referenced the model GPT-5.3-Codex as an available option for learners to experiment with.

---

New behavior / text:

The model reference has been updated from GPT-5.3-Codex to GPT-5.4. This ensures learners see current, available AI models when following the lab instructions. When they look for models in the model selector dropdown, they will be guided toward realistic, up-to-date options.

---

File 2: Instructions/Labs/Lab-5-Agentic-Coding.md

Old behavior / text:

Line 223 instructed learners to "run the commands below" without explicitly mentioning terminal creation.

---

New behavior / text:

The instruction now explicitly clarifies that learners should first create a new terminal before running the Git configuration commands. This removes ambiguity and improves the learner experience by:

• Preventing confusion if they already have a terminal open
• Ensuring a clean terminal environment
• Making the workflow clearer and more explicit

File 3-12: Media/Screenshot Updates

The following 10 screenshot files have been updated:

1. media/E2S1S1.png — Updated screenshot for Lab-2, Step 1
2. media/E2S1S2.png — Updated screenshot for Lab-2, Step 1
3. media/E3S3S2.png — Updated screenshot for Lab-3, Step 3
4. media/E3S3S3.png �� Updated screenshot for Lab-3, Step 3
5. media/E4S2S1.png — Updated screenshot for Lab-4, Step 2
6. media/E4S2S2.png — Updated screenshot for Lab-4, Step 2
7. media/exc3-best-practices-prompt.png — Updated best practices reference screenshot
8. media/model-picker.png — Updated model selector screenshot
9. media/new-models.png — Updated available models screenshot

Learner Impact:

These updated screenshots ensure that the visual guidance in the lab matches the current GitHub Copilot interface (as of May 2026). Without these updates, learners following the lab might see different UI elements, model names, or layouts in their actual GitHub Copilot experience, causing confusion and cognitive load.
