-    This release supports basic viewing and analysis of CSV files but there are some important limitations and caveats:
-    <ul>
-      <li>This initial release is for macOS only (no Windows or Linux builds yet, sorry).
-      <li>This release only supports CSV files imported into an internal SQLite instance; there is no connectivity to other SQL databases.
-      <li>There is no cell selection or Cut / Copy / Paste.
-      <li>The only aggregation functions provided are those supported natively by SQLite: <code>min</code>, <code>max</code>, <code>sum</code>, <code>count</code>.
-      <li>There is no support for interactive filtering of data.
-      <li>Due to an outstanding issue, opening Tad multiple times will result in multiple instances of Tad starting (and appearing in the Dock).
-    </ul>
-    <P>This is an <emph>initial release</emph>, so there is a reasonable chance you'll encounter bugs, UI annoyances, and corner cases. Please report them via <strong>Help...Send Feedback</strong>.
