    • Issue with getting collection name when we have no mappings for a marketplace.
    • Issue with alphart when getting collection name while filtering.
  • Improved the performance of extension. - Now we save the ranks for the NFTs you see in the local storage so when you visit it next time it will be shown faster. Also we don't make a lot of requests to ranking sites anymore.
  • Improved the layout of rankings. (Still some improvements to be done)
    • Made the ranks to be links that will redirect you to the ranking page.
      • NOTE: On Alpha.art you have to right click on the rank and click on open in new tab.

      • Issue with setting multiple mappings.
        • Now you are able to open the popup in a new tab and you will be able to insert multiple mappings.

        • Now also the NFTs with leading zero in the number will be fetched.
    • Fixed issue with clicking on ranks for alpahart, now you can directly click on them and it will get you to the ranking page directly.

  • New changes/ added features:

    • Added new marketplaces: - Digitaleyes.market - Exchange.art
      • Removed statistical rating and normalized traits from howrare (ST, NT) based on user feedback.

  • Added special mapping for Turtles collection. Now you can see ranks from howrare for turtles too. NOTE: Some turtles don't have ranks on howrare and moonrank (Boring Turtle, Zapi), if you find them please let me know and i will add them.

  • Added button in the popup to open it in a new page

  • Clear Cached Ranks Page:

    • Added option to clear the rankings.
    • Now in the popup you can go to the Ranks page and delete the collection you don't see that often or you added a new mapping for it and you want to refresh the ranks on the next page load.

  • Implemented a rate limiter for the requests sent to ranking providers and a sleep and retry process to fetch the ranks after the temporary block ends.

  • Added code (NF) to inform user to check for mappings.

    • If you see "NF" instead of ranking it means that the rankings are not found.

      • There can be 3 reasons for this :

        1. The rankings are not provided but this ranking provider.
        2. You need to add mappings for this new collection. NOTE: After you add a new mapping please refresh the page, to request new rankings. (See Clear Cached Ranks)
        3. There is a bug with the extension, if you checked that the collection is supported by the ranking provider you have added mappings for it and you still have the issue.Then please contact me (via discord or twitter) and I will try to help you.

      • If you see the loading icon, please wait until the requests are finished. It should take a few seconds. Currently when you try to look at too many NFTs (60 or more in 2-3 seconds by scrolling quickly).it will send all the request to ranking providers.

        Some of them may have limits in place for the amount of requests someone can do, for this reason they may temporarily restrict yuur access to their website for a few seconds.

        But no worries the extension will try to get the rankings again after the temporary ban is lifted, so don't worry and just wait a few and the rankings will show up.

NOTE: To ensure the best experience I advise you to scroll slowly to avoid sending too many requests in a short amount of time.

• 1.6 Release info:

• Fixed bugs:

  • Issue with solanart when you are in extended view mode. The ranks are shown now in all view modes.
  • Howrare changed their interface so code changes were needed to get rankings from new interface.
  • Issue with Moonrank ranks when filtering for Tower collection.
  • Added Solslugs as exception because howrare does not use leading zeros.
  • Implemented a request queue so that we don't hit howrare request limit. The request will be delayed so that we don't make more than 60 request per minute. They have said that they will release an API soon, will see then if it will be possible to improve this.

• Known issues:

• Sometimes for solanart moonrank hourglass can remain spinning for random NFTs, this only happens for a few and should get it if you refresh the page.

• Exchange art is buggy and requires some refreshes to be done when rankings are blocked loading.

• 1.7 Release info:

• Fixed bugs:

  -Fixed issue with saving the mappings and thresholds to local storage. -Fixed small issue with alphart footer and searching -Fixed issue with not checking again for moonrank rankings, if first time we check the ranks are not found. Now the extension will check again if more than 5 minutes have past since last time we checked. -Fixed issue for solanart when moonrank hourglass can remain spinning for random NFTs

• Changes:

  -Switched to Howrare API. -Added Quick buy button for MagicEden and Solanart. -Fixed some layout and performance issues with Solanart.

• Known issues:

  -Exchange art is buggy and i removed it for now. Will work on it and try to bring it back asap.

  -Fixed issues with exchange.art. Now the rankings should be shown again. -Fixed issues on Firefox with loading ranks, previous version was buggy. -Completely switched to Howrare API and improved performance from previous release. -Fixed some layout issue with Quick buy button. -Fixed small issue with not updating the colour of ranks when we change the threshold. -Added size in MB on Ranks page so you can see how much space ranks occupy on your system.

• Known issues:

  -Exchange art on Firefox fails sometimes for Howrare rankings. Will have to check why. -Collections : CryptoCribs, Solsteads Surreal Estate are currently not working with this extension. Reason for this is that a special mapping will be required for it to work. Will be looking into it and see how I can integrate these too.

• 1.8.1 Release info:

• Features:

  • Added option in Pop up Settings to disable or enable Quick Buy button.

Still using Manifest V2 until here.

Manifest V3 from here on for Chrome, Brave, Edge, Opera.

• 2.0 Release info:

• Features:

  • Added option in Pop up Settings to disable or enable Quick Buy button.
  • Added Raydium Marketplace, now you can also see rankings there. For this the mapping from Magiceden will be taken so no need for additional mapping.

• Changes:

  • Switched to using Manifest V3 and Service Workers. This should help have speedier reviews from chrome and also improve the performance.
  • Improved the way the extension stores the data, still work in progress.
  • Got rid of using localstorage so now all the data is stored in the indexedDB. One of the reasons is the storage limitations, not a lot of data is allowed to be stored in a single item. With previous approach there were issues with quickly recognising data mismatch, this caused an issue with loading ranks and it could have taken up to 5 minutes to recognise it and fetch the data again if necessary.
  • Added extra safety measures to make sure that Quick Buy is only triggered when it should.
  • Implemented also cleanup of the old stored data. This should prevent issue with saved settings.

• Known issues:

  • Unfortunately Firefox does not support Manifest V3 yet so you will not be able to manually import this extension there.

• 2.1 Release info:
