[N. J. A. Sloane]

1.  Sequences now have nice short URL's.  E.g. for sequence A000055:

http://www.research.att.com/projects/OEIS?Anum=A000055


2.  This URL now appears as the second line when you look at a sequence
via the web page.  The internal format has not changed, however.


3.  The third line has the word Sequence made into a link.
When you click it, you get a table showing the sequence in a numbered list;
also a version brackets suitable for feeding to Maple, Mma or other 
programs.


4.  Each entry shows the A-numbers of the three sequences
immediately before and after it in the lexicographic order.

This doesn't apply to recent sequences which are not yet in the
lexicographic order.  And it doesn't make much sense for
sequences at the start of the table. But otherwise it is very convenient 
for seeing the neighboring sequences.

This information is contained in a new %Y line, "Sequence in context".
This is part of the database, but it is added automatically.
Don't touch these lines!


5.  Decimal constants have the keyword "cons" made into
a link which shows you the decimal expansion as a real number
with the decimal point in the right place.


6.  I just did a major update of the OEIS.  The next couple of
months will be very busy here, and it may take longer than usual
to process comments and new sequences.  However, nothing will be
lost, I hope!
