(Contributed by Alan McIntyre and committed at the NeedForSpeed sprint.) % Patch 1442927 +\item It's now illegal to mix iterating over a file +with \code{for line in \var{file}} and calling +the file object's \method{read()}/\method{readline()}/\method{readlines()} +methods. Iteration uses an internal buffer and the +\method{read*()} methods don't use that buffer. +Instead they would return the data following the buffer, causing the +data to appear out of order. Mixing iteration and these methods will +now trigger a \exception{ValueError} from the \method{read*()} method. +(Implemented by Thomas Wouters.) +% Patch 1397960 + \item The \module{struct} module now compiles structure format strings into an internal representation and caches this representation, yielding a 20\% speedup.
