<H3> <A name="s2"> 5.1. release notes </A> </H3>
<P> ------------------ 0.41 ----------------------------
<P> Pd may be compiled in 64 bit address spaces; this is well tested on
linux and at least seems to work on Microsoft and MacOS. On linux, in fact,
if you compile Pd in a 64-bit version of the OS it's automatically in the
64 bit address space.
<P> In linux, a "-nosleep" flag causes Pd to poll instead of sleeping as it
waits for dac and adc; this is useful on multiprocessors when you don't mind
having Pd occupy 100% of one processor and want to get latency as low as
possible. (If you don't use this, latency on multiprocessors---Intel Core 2 at
least---is much worse for some reason than it is on uniprocessors.) It's
"experimental" but I use it every day.
<P> added an experimental callback scheduler. This might reduce latency in
MacOS and/or Microsoft, although I haven't seen that actually happen yet.
<P> removed limitation on huge messages from text files; this prevented long
"data" arrays from reloading from disk correctly.
<P> fixed crash bug closing patches with open GOPs.
<P> changed selection strategy so that, right after duplicating a collection
of objects, clicking tends to select an already-selected object.
<P> the cursor changes slightly more apprpriately when switching between edit
to run modes.
<P> got really confused about the proper role of "declare 'path" in abstractions;
for the moment they are ignored. I the future, it may be worthwhile to allow
them but to have them act only locally to the abstraction; but this might mean
a lot more computation overhead when opening files.
<P> limited window sizes to that of the screen (otherwise, on Mac OS, it's
impossible to resize them.)
<P> fixed "startup" dialogs to allow unlimited "path" and "lib" entries
<P> started, but didn't finish, the process of getting Pd to compile with
t_float as 64 bits. This would slow Pd down but improve tabread4~'s accuracy.
<P> made IEM Guis respect "-font" flag and friends. New startup flags:
"-font-face" (badly named); "-font-size" sysnonym of "-font". (Large patch from
HC).
<P> String overflow protection here and there.
<P> migrated to ".net" compiler ("VC 2005", a free download).

---------------- dolist --------------------
fixed crash bug closing patches with open GOPs
fixed PC device counting problem (first device invoked by -audiodev 0)
fixed MSTACKSIZE limitation in m_binbuf.c
fixed so that if more than one object is selected, clicking prefers to
"hit" a selected one (better dragging after "duplicate")
test:
compile on various versions of linux
windows:
