## Version history (last 5 releases)

### 8.3.1 — 2026-09-02

FIXED
• Training plans that would not open — showing "could not be loaded" or a connection error — now load correctly. This affected group plans and the coach's daily view.

Thanks for using NexRex!

### 8.3.0 — 2026-08-31

NEW
• Reminders — hydrate, refuel, wind down, morning weigh-in. Start from a runner-tested template or build your own. Today's reminders appear on your home screen; complete or skip in a tap.
• Pre-run settings — metronome cadence, auto-pause and auto-lap, right from the prep screen.
• Edit the details of a scanned food so your nutrition log stays accurate.
• Coaches: browse the Today plan across a range of dates.

IMPROVED
• Coaches see each athlete's personalized pace instead of a zone label.
• Clearer weekly reviews.
• Average pace now appears in your zone distribution.
• Runs that are still syncing show a processing status.

FIXED
• Completing or skipping a home-screen reminder now works and clears the card.
• Group plan scheduling and week locks now reconcile correctly.

Thanks for using NexRex!

### 8.2.0 — 2026-08-20

You can now choose Rex or Joy in Settings. If your team offers its own Agent, it appears in the same selection screen. Your choice now stays consistent across chat, activity summaries, weekly reviews, training adjustments, and daily guidance.

This update also keeps Agent names and visual identity consistent, and safely returns to your default Agent when another option is temporarily unavailable.

Thanks for using NexRex!

### 8.1.0 — 2026-08-12

A redesigned Training Calendar makes your training week easier to read — a cleaner layout with compact and spacious views, a quick plan switcher, and one-tap access to weekly summaries and coach notes.

Also in this release:
- New training-plan summary card on your home screen
- Fixed workouts disappearing after viewing a locked week
- Various bug fixes and stability improvements

Thanks for using NexRex!

### 8.0.3 — 2026-08-04

This update includes bug fixes and stability improvements across recovery tracking and training plans.

Thanks for using NexRex!
