Jan 1, 2025January 2025 (iotaledger/iota) focused on stabilizing wallet features, hardening asset-detail security, and improving readability for tiny decimals. Key outcomes include stabilizing vesting tests in wallet-dashboard by updating mocked vesting utilities and addressing failing tests; temporarily skipping failing vesting tests to unblock development (to be revisited in a separate ticket), followed by unskipping and fixing vesting.spec.ts to restore stability. Also delivered security hardening by removing clickable HTTP links in NFT asset details across wallet and wallet-dashboard, showing URLs as plain text to mitigate risks. Additionally, introduced subscript formatting for very small decimal amounts in the wallet interface, including a tooltip displaying the full amount and a refactor of amount formatting to handle leading zeros after the decimal. These changes span the iota repository (wallet and wallet-dashboard), improving CI reliability, reducing flaky tests, and enhancing data readability for users.
