YPP Mantid - Rent - Meridian

28^th April 2026

Ocean Populations
- Now I have almost 2 years of data, I added "1 Year" to range selection and made it the default
- Tidied up code and the back end. Removed jquery library.

16^th April 2026

Commodites Market
- Added "search" field
- Now allows viewing of ALL commodities from ALL islands at once (over 37,000 rows on Emerald - can be a little slow to filter)
- Improved performance
- Automatically clears cache and reloads data (new data should be available every 10 minutes)

14^th April 2026

Egg Designs
- Improved automagically rendered version resolution
- Improved performance

13^th April 2026

Scenes
- Fixed specific base tile fringe case
- Added Mermaid Class Sloop xml files
- Removed competition instructions, change default scene to current months limited edition vessel

12^th April 2026

Token Counter
- Added total mass to relevant token types
Sword Patterns
- Changed colouring process of sword icons to match rest of site

7^th March 2026

Trade Routes: New tool ready for testing - Show trade options for set routes
- With no islands selected it shows the ocean-wide arbitrage (you can click on the island name to expand/collapse them)
- With 1 island selected - it show the arbitrage for that island
- With 2 or more islands it shows profitable trade options, in the appropriate order
- Can filter trades by minimum profit
- Can choose a vessel to limit size of trades
- Would love any feedback/suggestions
Fleet Management: New tool ready for testing - Manage stock for a fleet
- Uses data that can be exported from the fleet management window of a docked vessel
- Sums available stock, calculates quantities required and prices at the current island
- Again, would love any feedback/suggestions
Shipwrightery Planner
- Bugfix: Board could show an incorrect tile if ye dragged it off of the board

25^th February 2026

Blacksmithing Planner
- I've added the ability to add (2) single character notes to each square
- Just mouse over the square and press a key
- You can switch between a left/right note with radio boxes on the side - or by pressing `TAB` or left/right arrowkeys
- `Backspace`, `Delete` & `Spacebar` all delete the note - if the note is empty it will try delete the 'other' note on that square
- These notes persist between pinned sequences / resets - but clear with a new screenshot

29^th January 2026

Commodites Market
- You can now view prices oceanwide - if searching by commodity
Interactive maps
- Clicking on a commodity's name in the side panel takes you to the Commodites Market with full ocean prices, instead of a yppeadia article

28^th January 2026

Interactive maps
- Added portrait item counters, mouse over the ocean memorization progress bar in the top left to see them
- Links that used to open a market viewer within the maps page now open a new tab instead, with the appropriate data shown in Commodites Market
Commodites Market
- Bugfix: Reloading cached data (if last update was less than 10 minutes) will no longer get stuck on "loading..."

20^th January 2026

Interactive maps
- Bugfix: Holding CTRL, click & dragging over league points marks them as known once more (Looks like I broke it on the 4th)
