beatnik, in answer to your original question, nothing has changed in the allocation or usage of the frequencies around Bournemouth and Southampton, it is simply a chart publication error.
In addition to
Mad Girl's
Fly On Track link, the relevant chart amendments for the Solent CTA frequencies can also be found
here on the CAA website, via the link for the appropriate chart on the left-side of the page, under reference 12354 and 12396.
Amendments for current aeronautical charts are also notified by the CAA as part of their general publication and newsletter subscription service, which is free and you can selectively register
here if you are interested.
Hope this helps ...
