+0.5.1 (??/??/201?):
+-------------------
+
+- Fixed bug that caused some programs (EFI shells, in particular) to hang
+ when launching on some systems (DUET, in particular).
+
+- Implemented a fix to enable ELILO to launch with Secure Boot active.
+ This fix might help with some other boot loaders in Secure Boot mode,
+ too, but I don't know of any specifics.
+
+0.5.0 (12/6/2012):
+------------------
+
+- Added the ability to include quote marks ('"') in refind.conf and
+ refind_linux.conf tokens by doubling them up, as in:
+ "ro root=/dev/sda4 some_value=""this is it"""
+ This example results in the following string being passed as an
+ option:
+ ro root=/dev/sda4 some_value="this is it"
+
+- Changed refind.conf-sample to uncomment the scan_all_linux_kernels
+ option by default. If this option is deleted or commented out, the
+ program default remains to not scan all Linux kernels; but with
+ increasing numbers of distributions shipping with kernels that include
+ EFI stub loader support, setting the configuration file default to scan
+ for them makes sense.
+
+- Modified the "resolution" token so that it affects text mode as well
+ as graphics mode. On my systems, though, the actual text area is still
+ restricted to an 80x25 area. (This seems to be a firmware limitation; my
+ EFI shells are also so limited.)
+
+- Fixed a bug that caused the options line editor to blank out lines that
+ were not actually edited.
+
+- Added support for using Matthew Garrett's Shim program and its Machine
+ Owner Keys (MOKs) to extend Secure Boot capabilities. If rEFInd is
+ launched from Shim on a computer with Secure Boot active, rEFInd will
+ launch programs signed with either a standard UEFI Secure Boot key or a
+ MOK. For the moment, this feature works only on x86-64 systems.
+
+- Added new "dont_scan_files" (aka "don't_scan_files") token for
+ refind.conf. The effect is similar to dont_scan_dirs, but it creates a
+ blacklist of filenames within directories rather than directory names.
+ I'm initially using it to place shim.efi and MokManager.efi in the
+ blacklist to keep these programs out of the OS list. (MokManager.efi is
+ scanned separately as a tool; see below.) I've moved checks for
+ ebounce.efi, GraphicsConsole.efi, and TextMode.efi to this list. (These
+ three had previously been blacklisted by hard-coding in ScanLoaderDir().)
+
+- Added the directory from which rEFInd launched to dont_scan_dirs. This
+ works around a bug in which rEFInd would show itself as a bogus Windows
+ entry if it's installed as EFI/Microsoft/boot/bootmgfw.efi.
+
+- Added support for launching MokManager.efi for managing the Machine Owner
+ Keys (MOKs) maintained by the shim boot loader developed by Fedora and
+ SUSE. This program is scanned and presented as a second-row tool.
+
+- Added support for Apple's Recovery HD partition: If it's detected, a new
+ icon appears on the second row. This icon can be removed by explicitly
+ setting the "showtools" option in refind.conf and excluding the
+ "apple_recovery" option from that line.
+
+- Fixed bug that caused text-mode ("textonly" refind.conf option enabled)
+ menu entries to be right-aligned rather than left-aligned when rEFInd was
+ compiled with the TianoCore EDK2.
+
+- Added "--usedefault {devicename}" and "--drivers" options to the
+ install.sh script and changed the "esp" option to "--esp".
+
+0.4.7 (11/6/2012):
+------------------
+
+- Added an icon for gummiboot.
+
+- Added a boot option editor: Pressing the Insert or F2 key from a boot
+ tag's options menu opens a simple text-mode line editor on which the boot
+ options may be edited for a one-time boot with altered options.
+
+- Modified the "scan_delay" feature to delay and then perform a re-scan,
+ which may work better than the first attempt at this feature (which I'm
+ told isn't working as planned).
+
+- Modified rEFInd to add a space after the command-line options only when
+ launching Mac OS X. On some early Macs, the extra space (which had been
+ present by default, as a carryover from rEFIt) causes problems when
+ booting Linux kernels from FAT partitions.
+
+0.4.6 (10/6/2012):
+------------------
+
+- Fixed some minor memory management issues.
+
+- Added new "scan_delay" feature to impose a delay before scanning
+ for disks.
+
+- Changed default "scanfor" option from internal-external-optical to either
+ internal-external-optical-manual (for non-Macs) or
+ internal-hdbios-external-biosexternal-optical-cd-manual (for Macs). I've
+ done this for two reasons:
+ - Many Mac users have been confused by the fact that rEFInd needs
+ reconfiguration to detect Windows (or Linux installed in BIOS mode),
+ since rEFIt scans BIOS devices by default. Adding the BIOS options as
+ default for them should help them.
+ - Adding the "manual" option enables users to simply add manual boot
+ stanzas and have them work, which is more intuitive. Adding the
+ "manual" option will have no effect unless manual stanzas are created
+ or uncommented, so this part of the change won't affect users' working
+ default configurations.
+
+- Added new legacy (BIOS) boot support for UEFI-based PCs.
+
+0.4.5 (8/12/2012):
+------------------
+
+- Fixed bug that caused a failure to boot BIOS-based OSes on Macs.
+
+- Fixed bug in install.sh that caused it to fail to detect rEFItBlesser.
+
+0.4.4 (6/23/2012):
+------------------
+
+- Fixed bug that caused filesystem labels to be corrupted by rEFInd on
+ 32-bit systems.
+
+- Fixed bug that caused filesystem labels to be truncated in the drivers
+ on 32-bit systems.
+
+- Fixed bug in use_graphics_for option parsing that caused most options
+ to set graphics mode for OS X and/or Linux but not other boot
+ loaders/OSes.
+
+- Tweaked install script to better isolate the ESP under OS X.
+
+0.4.3 (6/21/2012):
+------------------
+
+- rEFInd now supports compilation using the TianoCore UDK2010/EDK2
+ development kit in addition to GNU-EFI.
+
+- Added new "use_graphics_for" option to control which OSes to boot in
+ graphics mode. (This effect lasts for a fraction of a second on most
+ systems, since the boot loader that rEFInd launches is likely to set
+ graphics or text mode itself.)
+
+- Graphics-mode booting now clears the screen to the current rEFInd
+ background color (rather than black) and does NOT display boot messages.
+ The intent is for a smoother transition when booting OS X, or perhaps
+ other OSes that don't display boot loader messages. In practice, this
+ effect will be tiny for many OSes, since the boot loader generally clears
+ the screen within a fraction of a second of being launched; but the
+ "flicker" of a rEFInd message in that time can sometimes be distracting.
+
+- Filesystem drivers now work on EFI 1.x systems, such as Macs.
+
+- Removed "linux.conf" as a valid alternative name for "refind_linux.conf"
+ for holding Linux kernel options. The kernel developers plan to use
+ "linux.conf" themselves.
+
+0.4.2 (6/3/2012):
+-----------------
+
+- Added a message to install.sh when run on Macs to remind users to update
+ the "scanfor" line in refind.conf if they need to boot BIOS-based OSes
+ via rEFInd.
+
+- Modified install.sh script to be smarter about running efibootmgr on
+ Linux. It now uses the whole path to the rEFInd binary as a key to
+ determine whether an existing entry exists, rather than just the filename
+ portion. If an entry exists and is the first entry in the boot order, the
+ script does nothing to the NVRAM entries. If such an entry exists but is
+ not the default, the script deletes that entry and creates a new one
+ (implicitly making it the first in the boot order). If such an entry does
+ not exist, the script creates a new one (again, making it the first in
+ the boot order).
+
+- Added "dont_scan_dirs" configuration file option, which adds directories
+ to a "blacklist" of directories that are NOT scanned for boot loaders.
+
