+	* doc/fconfigure.n, doc/CrtChannel.3: Updated to reflect the fact that
+	the minimum buffer size is one byte, not ten. Identified by Schelte
+	Bron on the Tcler's Chat.

 	* generic/tclExecute.c (TEBCresume:INST_INVOKE_REPLACE):
 	* generic/tclEnsemble.c (TclCompileEnsemble): Added new mechanism to
 	allow for more efficient dispatch of non-bytecode-compiled subcommands

 \fBTcl_SetChannelBufferSize\fR sets the size, in bytes, of buffers that
 will be allocated in subsequent operations on the channel to store input or
-output. The \fIsize\fR argument should be between ten and one million,

 allowing buffers of ten bytes to one million bytes. If \fIsize\fR is
 outside this range, \fBTcl_SetChannelBufferSize\fR sets the buffer size to
