This list contains the changes in the {\GAP} character table library
since the official upgrade for {\GAP}~3.4 in October 1996.
We denote mathematical errors by {\bf ***} and new information
by {\bf NEW}\null.
We use {\bf C} to denote changes that are not obviously corrections;
the number of these changes is kept small.

C&Whitespace at the end of {\tt InfoText} strings was removed.\cr
NEW&Various class fusions were added.\cr
NEW&Components {\tt tomidentifier} and {\tt tomfusion} were added
in order to provide a (preliminary) interface to
the library of tables of marks.\cr
C&In the library tables of alternating and symmetric groups,
the {\tt classtext} components
(partitions parametrizing the conjugacy classes;
in some cases, this had been hidden inside the {\tt CAS}
component of the table)
were replaced by values of the attribute {\tt ClassParameters}.\cr
NEW&The tables of $L_2(q)$ were added for those values of $q$ for which
the table of marks of $L_2(q)$ is now contained in the {\GAP} library.\cr
NEW&In the library tables of symmetric groups,
the partitions parametrizing the irreducible characters
are stored on the tables,
as value of the attribute {\tt CharacterParameters}.\cr
C&The {\tt Identifier} values of a few tables have been changed.
For example, the table of {\tt L4(3).2\^{}2} was previously known only as
{\tt psl(4,3).v4}.
The old names are still valid.\cr
***&The character tables with identifiers {\tt iu332}, {\tt D2MJ4},
and {\tt P4L82} were removed.
The former two tables were incomplete, the latter one was wrong.\cr

to {\tt 2\^{}10:L5(2)}.\cr % Make the old table available again, with the old name! (ctomaxi6.tbl)
NEW&McL&:&The table of the seventh maximal subgroup of $McL.2$ was added.\cr

***&Element orders and power maps in the table with identifier
{\tt s61p} were corrected.\cr
***&The table with identifier {\tt 2.cenc1} was removed because it was
inconsistent.\cr % no power maps possible ...
C&Two instances of the table of $(A_6 \times A_6):2^2$ were unified.\cr
C&The tables with identifiers {\tt J2.2M4}, {\tt 2\^{}(2+4):(3x3):2\^{}2},
and {\tt 2\^{}(2+4):(S3xS3)} were unified;
the identifiers {\tt J2.2M5} and {\tt 2\^{}(2+4):(S3xS3)} can be used to

it is replaced by the table with identifier {\tt U3(5).3.2}
whose cosets of the outer automorphism group are ordered as in the
Atlas of Finite Groups.
The identifier {\tt U3(5).S3} is now admissible for the table with
identifier {\tt U3(5).3.2}.\cr
***&U_4(3)&:&The table with identifier {\tt u4q3c} was removed;
characters and power maps of this table were erroneous.

which can be accessed with the name {\tt 3\_2.U4(3).2\_3'}.\cr

for $L_2(q)$, for various values of $q$,

this includes direct products and tables of small groups that can be computed
easily with standard methods.
The other way round, each ordinary table in the library for which the table

from the ordinary one; now this function has been corrected.

$2.Ru$,
$3.F_{3+}$,

$3.McL$,
$3.ON$,
$6.Suz$, and
$12.M_{22}$.
At the time when the {\CAS} library got included in
{\GAP}'s character table library,
this information was apparently not saved.
However, at least the book ``Brauer Trees of Sporadic Groups'' refers
to the {\CAS} numbering of certain characters,
thus it is useful to make the values available.
Thanks to Gerhard Hiss for the {\CAS} format tables
which had been used in the computations for the abovementioned book.\cr}

NEW&The tables of all maximal subgroups are available for $F_4(2).2$ and $M$. \cr
***&Side-effects of the now known classification of maximal subgroups
of the Monster group $M$ are that the previously claimed maximal subgroups
of the type $L_2(59)$ do not exist (and hence the Monster has
maximal subgroups of the type $59:29$), and that the ordering of the
classes $39$ to $45$ of maximal subgroups had to be changed,
in order to achieve that the numbering reflects descending subgroup order.\cr

The only change was that the ordering of rows and columns of the
table of $S_4(8).3$ (which had been added in version~1.3.10)
was adjusted such that the function {\tt AtlasClassNames}
(from the {\GAP} package {\tt AtlasRep}) does not run into an error
when called with this table.
