microcode version 11.33, which is required for this runtime system
version.
* The low-level channel abstraction has been changed -- it now
contains only a microcode channel descriptor and the channel type.
The microcode no longer knows the format of channels.
* Subprocess support has been temporarily removed. New subprocess
support is being designed to accompany changes in the microcode.
* The file-copy primitive is now written in Scheme using lower-level
file system and I/O operations.
* Use `input-port/immediate-mode' and `input-port/normal-mode' to
switch terminal mode. The operations `read-char-immediate' and
`peek-char-immediate' are now obsolete. REP loops force the input
port into normal mode, while the debugger forces it into immediate
mode.
* I/O buffering for input files, output files, and the console output
is now done in Scheme. The microcode provides no buffering.
These ports understand `buffer-size' and `set-buffer-size' operations
to control the amount of buffering. A buffer size of 0 disables
buffering entirely.
* `read-start!' and `read-finish!' are now optional operations on
input ports.
* An input or output port will now report the set of operations that
it responds to.
