Original six tasks (500 XP, Iron Sword, 10 Diamonds, Totem, 30 Bow uses, 10 Deaths) are unchanged in goal.

Rewards are now attribute modifiers instead of overwriting base values, so they stack and no longer cancel each other (previously the diamond reward overwrote the death reward's armor).
All upgrade functions now run per player (@s). Before, they targeted @p / the server, which could reward the wrong player in multiplayer.
The Totem reward now matches its message: +5% speed (it previously set the base speed to 0.15, which is +50%).
The Diamond task now also counts Deepslate Diamond Ore.
Task menu (/trigger tasksgui) now shows progress (e.g. 12/500), the reward for each task, and a completed counter. Hover a task to see its reward.
Level-up sound when a task is completed; max-health rewards also heal you.
Progress is no longer reset on /reload or server restart (the load function used to zero everyone's scores).
Players who join later are tracked correctly (previously their "done" flags were never initialised).
New: /trigger tasksgui set 2 shows the changelog in chat.
New: /execute as <player> run function playerprogress:admin/reset wipes a player's progress and rewards (needs op).
Rewards are re-applied automatically after death as a safety net.

Replace the old datapack and run /reload.
Existing progress and completed tasks are kept. On first tick, each player with completed old tasks has their base attributes reset to vanilla defaults and the rewards re-applied as modifiers.
The 14 new tasks start counting from 0; earlier activity is not counted for them.
If you changed a player's armor/health/speed/attack base values by other means, the one-time migration resets those five attributes for players who had completed old tasks.
