The Google Webmaster Tools Team has updated the robots.txt analysis tool so that the new sitemaps autodiscovery line does not generate an error like it did last week.

Example error: -Syntax not understood.

Vanessa Fox also states that "Last month, we replaced the individual anchor text words that we showed for your site in webmaster tools with a list of full anchor phrases. "

The new changes are:
   * We've expanded the number of phrases we show to 200.
   * You can now see the variations of each phrase (for instance, with different capitalization and punctuation).
   * More sites now have access to the anchor phrase report. So, if you didn't have this report before, you may have it now.
   * We've brought back the report showing the most common individual words in anchor text (you asked; we delivered!).
   * We've expanded the number of common words in anchor text and common words in your site that we show to 100 each.
