Changelog

Full release history and version notes for Base64 Encoder/Decoder.

Version 2.0

Latest June 2026

First release under the Base64 Encoder and Decoder name and the first release on the Microsoft Store — same engine, refreshed identity and packaging.

New & Changed

  • Rebranded to Base64 Encoder and Decoder — window title, navigation rail, About dialog and installer metadata all updated
  • New brand logo, shown with rounded corners in the navigation rail and About dialog
  • First release distributed through the Microsoft Store
  • Polished Text tab — bordered editor cards, a per-editor footer with a live character count and a Clear link, a Copy chip on the Output header, and action buttons with consistent icons and widths
  • Navigation rail gained a bottom action row with a theme toggle (sun/moon, synced with your saved theme) and an About button
  • About dialog widened so the full product name fits on one line, with a refreshed information block, a clickable backendside.com link, and a build stamp shown alongside the version

Fixed

  • Fixed an icon-rendering issue that could prevent the app window from opening on some setups
