+This document details the changes between this version, bash-2.01.1-release,
+and the previous version, bash-2.01-release.
+
+1. Changes to Bash
+
+a. The select command was fixed to check the validity of the user's
+ input more strenuously.
+
+b. A bug was fixed that prevented `time' from timing commands correctly
+ when supplied as an argument to `bash -c'.
+
+c. A fix was made to the mail checking code to keep from adding the same
+ mail file to the list of files to check multiple times when parsing
+ $MAILPATH.
+
+d. Fixed an off-by-one error in the tilde expansion library.
+
+e. When using the compound array assignment syntax, the old value of
+ the array is cleared before assigning the new value.
+
+f. Fixed a bug that could cause a core dump when a trap handler was reset
+ to the default in the trap command associated with that signal.
+
+g. Fixed a bug in the locale code that occurred when assigning a value
+ to LC_ALL.
+
+h. A change was made to the parser so that words of the form xxx=(...)
+ are not considered compound assignment statements unless there are
+ characters before the `='.
+
+i. A fix was made to the command tracing code to correctly quote each
+ word of output.
+
+j. Some changes were made to the bash-specific autoconf tests to make them
+ more portable.
+
+k. Completion of words with globbing characters now correctly quotes the
+ result.
+
+l. The directory /var/spool/mail is now preferred to /usr/spool/mail when
+ configure is deciding on the default mail directory.
+
+m. The brace completion code was fixed to not quote the `{' and `}'.
+
+n. Some fixes were made to make $RANDOM more random in subshells.
+
+o. System-specific changes were made to configure for: SVR4.2
+
+p. Changes were made so that completion of words containing globbing chars
+ substitutes the result only if a single filename was matched.
+
+q. The window size is now recomputed after a job is stopped with SIGTSTP if
+ the user has set `checkwinsize' with `shopt'.
+
+r. When doing substring expansion, out-of-range substring specifiers now
+ cause nothing to be substituted rather than an expansion error.
+
+s. A fix was made so that you can no longer trap `SIGEXIT' or `SIGDEBUG' --
+ only `EXIT' and `DEBUG' are accepted.
+
+t. The display of trapped signals now uses the signal number if signals
+ for which bash does not know the name are trapped.
+
+u. A fix was made so that `bash -r' does not turn on restricted mode until
+ after the startup files are executed.
+
+v. A bug was fixed that occasionally caused a core dump when a variable
+ found in the temporary environment of export/declare/readonly had a
+ null value.
+
+w. A bug that occasionally caused unallocated memory to be passed to free()
+ when doing arithmetic substitution was fixed.
+
+x. A bug that caused a buffer overrun when expanding a prompt string
+ containing `\w' and ${#PWD} exceeded PATH_MAX was fixed.
+
+y. A problem with the completion code that occasionally caused it to
+ refer to a character before the beginning of the readline line buffer
+ was fixed.
+
+z. A bug was fixed so that the `read' builtin restarts reads when
+ interrupted by signals other than SIGINT.
+
+aa. Fixed a bug that caused a command to be freed twice when there was
+ an evaluation error in the `eval' command.
+
+2. Changes to Readline
+
+a. Added a missing `extern' to a declaration in readline.h that kept
+ readline from compiling cleanly on some systems.
+
+b. The history file is now opened with mode 0600 when it is written for
+ better security.
+
+c. Changes were made to the SIGWINCH handling code so that prompt redisplay
+ is done better.
+
+d. ^G now interrupts incremental searches correctly.
+
+e. A bug that caused a core dump when the set of characters to be quoted
+ when completing words was empty was fixed.
