<hr />
<ul>
+<li><b>0.7.0 (6/27/2013)</b>—Improvements to the filesystem drivers dominate this version. The biggest change is a new Btrfs driver, created by Samuel Liao and based in part on the GRUB 2.0 Btrfs support. The drivers also now include a read cache to improve their speed. This has only a tiny effect on most computers, but on some it can speed boot times by a few seconds, and under VirtualBox the effect is dramatic—the ext2fs driver goes from a sluggish three <i>minutes</i> to load a kernel and initrd to three <i>seconds</i>. I've also changed some critical filesystem driver pointers from 32-bit to 64-bit, which may enable some of them to work with larger filesystems, although this isn't yet tested. The main rEFInd binary sports only two changes: It can now identify Btrfs volumes as such for labelling purposes and it can now filter out invalid loaders (those for the wrong architecture or Linux kernels that lack EFI stub loader support, for instance).</li>
+
+<li><b>0.6.12 (6/18/2013)</b>—This version changes relatively little code, but it adds one feature that will simplify rEFInd installation for some users: The program can now deduce minimal Linux boot options based on an <tt>/etc/fstab</tt> file <i>if</i> that file is on the same partition as the kernel (in other words, if you do <i>not</i> use a separate <tt>/boot</tt> partition). Put another way, <tt>refind_linux.conf</tt> is no longer required for some installations, although it's still desirable. If you're already using rEFInd, this isn't likely to be important, but it can help when you're just starting out. In addition, this version adds support for the Linux Foundation's PreBootloader in the <tt>install.sh</tt> script. I've also changed the default 64-bit shell included on the CD-R and USB flash drive images to a modified version 2 shell, so as to enable use of the <tt>bcfg</tt> command to help install rEFInd (or make other changes to the firmware's boot manager configuration).</li>
+
+<li><b>0.6.11 (5/13/2013)</b>—Two new features may have a noticeable affect for many users: First, rEFInd now ignores symbolic links on filesystems that support them. I've implemented this change because I've been receiving too many reports from users who want to remove redundant or non-functional Linux boot entries caused by symbolic links created by distributions. Although this is possible by editing the <tt>dont_scan_dirs</tt> or <tt>dont_scan_files</tt> options in <tt>refind.conf</tt>, telling users how to do this has become tedious. If you <i>want</i> to use links to create multiple entries for one kernel or boot loader, use hard links instead of symbolic links. The second major user-visible change is that rEFInd now tries to guess the distribution type based on the naming of the kernel file (effective only for Fedora and RHEL) or the contents of the <tt>/etc/os-release</tt> file (effective only if the installation does <i>not</i> have a separate </tt>/boot</tt> partition or if <tt>/etc/os-release</tt> is copied to that location on the partition that holds the kernel). There are several other minor cosmetic issues that some users may notice, including icons for Lubuntu and Kubuntu and a change in the name of the "Reboot to Firmware User Interface" option to "Reboot to Computer Setup Utility." I've also fixed a bug in <tt>gptsync</tt> that could cause it to hang if the disk had too few GPT partitions. Finally, I've improved the <tt>install.sh</tt> script so that it works better from a path with directory names that include spaces.</li>
+
+<li><b>0.6.10 (5/5/2013)</b>—This version adds a number of minor improvements: The ability to create multiple screen shots under a sequence of names rather than using just one name; a new screen saver feature, activated by the <tt>screensaver</tt> token in <tt>refind.conf</tt>; and an option to reboot the computer into the firmware's setup utility on computers that support this feature. I've also added an OS for ChromeOS (<tt>os_chrome.icns</tt>), and I've updated the LodePNG library to the latest version, which might improve rendering of some PNG files.</li>
+
+<li><b>0.6.9 (4/25/2013)</b>—The most visible change to this version is to the rEFInd banner image, which now includes an icon provided by Erik Kemperman. The biggest change with this version is the inclusion of an updated version of <tt>gptsync</tt>, which is popular on Macs as a means of maintaining the <a href="http://www.rodsbooks.com/gdisk/hybrid.html">hybrid MBR</a> that's required to boot Windows in BIOS mode on that platform. Because hybrid MBRs are ugly and dangerous, though, the rEFInd <tt>install.sh</tt> script installs the program only under OS X, and even then it must be activated by uncommending the <tt>scanfor</tt> line in <tt>refind.conf</tt> and adding <tt>gptsync</tt> to its options list. If you want to use <tt>gptsync</tt> on a PC, you can, but you'll need to copy the program file manually to the ESP's <tt>EFI/tools</tt> directory. Other changes with this version include working around a suspected firmware bug that can cause hangs when rEFInd starts on some systems and changing the timeout code so that rEFInd will launch its default OS even if the computer is started without a keyboard.</li>
+
+<li><b>0.6.8 (3/18/2013)</b>—This version fixes a few obscure bugs but adds only one minor new feature. Most notably, it fixes a problem that caused "Invalid Parameter" errors to appear when scanning for boot loaders on some systems; fixes a bug that caused icons defined in files named after boot loaders to not appear; and fixes a bug in the <tt>install.sh</tt> script that caused the script to fail on some systems. It also enables you to name a shell <tt>shell.efi</tt> in the root directory (previously only <tt>shell_<i>arch</i>.efi</tt> worked in the root directory, although <tt>shell.efi</tt> worked in the <tt>EFI/tools</tt> directory).</li>
+
+<li><b>0.6.7 (2/3/2013)</b>—This version fixes a few bugs and adds some minor features relating to Secure Boot. Bug fixes include keeping rEFInd out of its own menu when it's launched as <tt>EFI/Microsoft/Boot/bootmgfw.efi</tt>; keeping the <tt>dont_scan_volumes</tt> option out of the <tt>also_scan_dirs</tt> list; a fix for <tt>dont_scan_volumes</tt> so that it applies to the OS X boot loader; and a fix for a bug that caused PNG files in a user-specified icons directory to be ignored if an ICNS file was available in the standard icons directory. New features include support for the Linux Foundation's <tt>HashTool.efi</tt> as a MOK utility, scanning for MOK utilities on all volumes, and a more verbose error message when a Secure Boot authentication failure occurs.</li>
+
+<li><b>0.6.6 (1/26/2013)</b>—This version includes two new features and a number of minor bug fixes. The first new feature is support for changing rEFInd's font via the <tt>font</tt> token in <tt>refind.conf</tt>. You're limited to monospace fonts that are encoded as PNG files; you can't use variable-width fonts or normal font files like TrueType fonts. The fonts support only ASCII characters. See the <a href="themes.html#fonts">fonts section on the Theming rEFInd page</a> for details. I've also changed the default font to a slightly larger one that's anti-aliased. The second new feature is that rEFInd now detects when the <tt>EFI/BOOT/bootx64.efi</tt> (or <tt>EFI/BOOT/bootia32.efi</tt> on 32-bit systems) boot loader is a duplicate of another boot loader, and automatically excludes it from the OS list. This is useful on systems that boot with Windows, since Windows tends to install its boot loader twice, once using the <tt>EFI/BOOT/bootx64.efi</tt> filename. Bug fixes are described in the <tt>NEWS.txt</tt> file, and include fixes for bugs that prevented manual boot stanzas in included configuration files from being detected; that caused an <tt>ASSERT</tt> error to appear on the screen on some systems if <tt>default_selection</tt> was not set; the caused <tt>Binary is whitelisted</tt> messages to persist on the screen when loading signed EFI drivers with Secure Boot active; that caused rEFInd to ignore <tt>icon</tt> tokens in <tt>refind.conf</tt> manual boot stanzas; and that caused the <tt>install.sh</tt> script to fail to update drivers when rEFInd was installed to <tt>EFI/BOOT</tt>.</li>
+
+<li><b>0.6.5 (1/16/2013)</b>—Most of this version's changes relate to icon, graphics, and theming features. The biggest code change is in support for PNG files for banners, icons, and selection backgrounds. I've also fixed bugs that prevented large banners from being used; you can now use banners as big as the screen (or bigger, but they'll be cropped), as illustrated on the <a href="themes.html">Theming rEFInd</a> page. The text color also now automatically switches between black and white depending on the background over which it's displayed. If you don't use these features, you're likely to notice some changes in where certain elements are displayed. Most obviously, the banner appears higher on the screen than it did previously, so as to minimize the chance of overlap with text displays such as the information screen. These text displays should appear correctly even on tiny 640x480 displays (they were blank on such small displays in the past). I've added icons for <a href="https://www.haiku-os.org/">Haiku</a> and <a href="http://www.altlinux.com/">ALT Linux.</a> Finally, the only non-graphics development is the addition of a "safe mode" boot option for OS X, which you can disable by adding <tt>safemode</tt> to the <tt>hideui</tt> option in <tt>refind.conf</tt>.</li>
+
+<li><b>0.6.4 (1/8/2013)</b>—Bug fixes motivate this release; it corrects a couple of memory management bugs in 0.6.3 that cause rEFInd to hang at startup on some computers (unfortunately not on any of mine, so I missed this). I've also made a small change to the <tt>install.sh</tt> script so that it installs the ext2fs driver rather than the ext4fs driver if the script detects that a Linux kernel is on an ext2fs or ext3fs partition. This can keep rEFInd from scanning ext4fs partitions and picking up non-functional symbolic links to vmlinuz on such partitions.</li>
+
+<li><b>0.6.3 (1/6/2013)</b>—The installation script and related tools see the biggest changes in this version of the program. The <tt>install.sh</tt> script can now detect a rEFInd installation in <tt>EFI/BOOT</tt> or <tt>EFI/Microsoft/Boot</tt> and update it rather than install to the default location of <tt>EFI/refind</tt>. It will also install to one of these fallback locations if it's run in BIOS mode, thus helping users who want to get a BIOS-mode install of Linux running on an EFI-based computer. A new <tt>mvrefind.sh</tt> script can move the installation between these three locations (or more exotic locations). Outside of scripts, the <tt>dont_scan_dirs</tt> and <tt>also_scan_dirs</tt> tokens can now accept volume specifications, as in <tt>myvol:EFI/bogus</tt> to not scan (or scan) the <tt>EFI/bogus</tt> directory on the <tt>myvol</tt> volume. I've also fixed a bug that caused rEFInd to ignore default boot loaders on removable disks if rEFInd was installed using the fallback filename. I've also modified the ISO-9660 driver so that it works with ISO-9660 images written to non-optical media. This may help with getting "hybrid ISO" images written to USB flash drives to boot.</li>
+
+<li><b>0.6.2 (12/30/2012)</b>—This version's biggest changes are "behind-the-scenes" improvements. Specifically, I've completely re-worked the shim/MOK Secure Boot code, based largely on an approach used by James Bottomley in his PreLoader boot loader. This fixes some bugs, such as the inability to launch more than one EFI boot loader in Secure Boot mode. The EFI filesystem drivers can now be built with GNU-EFI, which may help distribution maintainers. I'm also providing RPM packages of rEFInd, although I recommend installing from the binary zip file. Finally, I've changed rEFInd's default text-mode setting behavior to not adjust the text mode. (Recent previous versions forced the system to use text mode 0, which cuased problems on some systems.)</li>
+
+<li><b>0.6.1 (12/21/2012)</b>—(Mayan apocalypse edition!) This version features a number of refinements and minor bug fixes. The <tt>install.sh</tt> script now includes a new <tt>--root</tt> option to enable easier installation of rEFInd to a regular OS installation from an emergency disc. The ext4fs driver now supports the <tt>meta_bg</tt> filesystem feature. I've fixed a number of obscure display resolution-setting bugs and a bug that caused the screen to clear after displaying certain error messages but before prompting you to continue. Instead of displaying a blank filesystem label as the "from" location for a boot loader, rEFInd now describes the filesystem by its type (FAT, ext4fs, etc.) and/or size. rEFInd also now uses the filesystem label as a hint about what type of icon to display for a boot loader.</li>
+
+<li><b>0.6.0 (12/16/2012)</b>—The donation of a working ext4fs driver from Stefan Agner has prompted another big jump in the rEFInd version number, since this driver will greatly simplify installation on many systems: You may be able to simply run the <tt>install.sh</tt> script to get a working rEFInd that boots your Linux kernels directly, bypassing GRUB or ELILO. Other improvements in this version include bug fixes and minor changes to <tt>install.sh</tt>, the addition of hint text to the rEFInd main menu, the ability to disable the options editor via the <tt>editor</tt> option to <tt>hideui</tt> in <tt>refind.conf</tt>, a new <tt>textmode</tt> option to <tt>refind.conf</tt> to set the size of the text-mode display, a change to the code that adds your initial RAM disk to the boot options so that if you specify one manually (via <tt>refind_linux.conf</tt>), it will take precedence, and assorted obscure bug fixes. The <tt>NEWS.txt</tt> file goes into more details about many of these changes, as do the relevant pages of this HTML documentation.</li>
+
+<li><b>0.5.1.1 (12/12/2012)</b>—This is a micro-update to fix a bug in the <tt>install.sh</tt> script that prevented it from working under OS X. Aside from that, and a few small documentation changes, this version changes nothing in rEFInd.</li>
+
+<li><b>0.5.1 (12/11/2012)</b>—The most important changes to this version are to the <tt>install.sh</tt> script. It now supports two options, <tt>--shim</tt> and <tt>--localkeys</tt>, to aid in installation on a Secure Boot system. See the <a href="installing.html">Installing rEFInd</a> and <a href="secureboot.html">Managing Secure Boot</a> pages for details. The script also now creates a sample <tt>/boot/refind_linux.conf</tt> file to assist in setting up boots via the Linux EFI stub loader. All of these <tt>install.sh</tt> improvements work only in Linux. A separate <tt>mkrlconf.sh</tt> script creates a <tt>/boot/refind_linux.conf</tt> file if it doesn't exist, for help in post-installation configuration. In rEFInd itself, I've fixed the bug that caused ELILO to be unable to locate its configuration file when launched in Secure Boot mode and fixed a couple of more obscure bugs. I've also added an <tt>include</tt> token to <tt>refind.conf</tt>, to enable you to create a secondary configuration file (say, one managed by scripts while leaving the main file untouched; or one dedicated to manual boot stanzas).</li>
+
+<li><b>0.5.0 (12/6/2012)</b>—I've focused on adding support for Matthew J. Garrett's shim program to this version of rEFInd; with this support, rEFInd is capable of launching Linux kernels and other programs signed with a suitable key while the computer is in Secure Boot mode. This initial release, however, requires significant manual configuration and has some known bugs and limitations. See the <a href="secureboot.html">Managing Secure Boot</a> page for details. Beyond this major new feature, this version includes several more minor improvements. These include a change to the <tt>resolution</tt> token so that it applies to text mode as well as to graphics mode; a bug fix that caused the line editor to blank out lines that were left unedited; a new <tt>dont_scan_files</tt> option to blacklist boot programs by filename; support for launching MokManager and Apple's Recovery HD partitions via tools (2nd-row) icons; new <tt>--usedefault</tt> and <tt>--drivers</tt> options to the <tt>install.sh</tt> script; a change of the <tt>esp</tt> installation script option to <tt>--esp</tt>; and the ability to use quote marks inside option strings by doubling them up.</li>
+
+<li><b>0.4.7 (11/6/2012)</b>—The most important new feature in this version is a boot options editor. From rEFInd's main menu, press Insert or F2 to see the options menu. Select one of the options and press Insert or F2 again and the screen switches to a text-mode display in which you can edit the options that will be passed to the boot loader. A second new feature is a new icon for <a href="http://freedesktop.org/wiki/Software/gummiboot">gummiboot,</a> which is another EFI boot manager. This version also alters the behavior of the <tt>scan_delay</tt> option, since I've been told that the previous version didn't work; the new one does. Finally, this version omits the space that followed boot options when booting most OSes. This behavior was inherited from rEFIt; a comment in the source code indicates it's needed by OS X, but I've been told it causes boot failures when launching Linux on some Macs. Thus, rEFInd now adds this space only when booting Mac OS X.</li>
+
+<li><b>0.4.6 (10/6/2012)</b>—Thanks to contributor John Bressler, rEFInd can now boot legacy (BIOS) boot loaders on many UEFI PCs. (Previously, rEFInd could do this only on Macs.) Other changes include a new <tt>scan_delay</tt> option that inserts a delay between rEFInd starting and disk scans (to help detect disks that are slow to appear to the firmware) and a change in the default <tt>scanfor</tt> value so that legacy OSes are detected by default on Macs (but not on PCs). I've also fixed some memory management problems that caused error messages to appear on some systems when rEFInd was compiled with the TianoCore EDK2 toolkit. Finally, I'm now using the TianoCore toolkit to make my primary binary builds, since the new UEFI legacy boot support requires the TianoCore environment. (rEFInd still builds with GNU-EFI, but it doesn't support booting legacy OSes on UEFI systems when built in this way.)</li>
+
+<li><b>0.4.5 (8/12/2012)</b>—This version fixes a couple of Mac-related bugs. The most important is that version 0.4.3 and 0.4.4 couldn't boot BIOS-based (aka CSM or Boot Camp) OS installations; 0.4.5 restores this important feature. The second bug is in the <tt>install.sh</tt> script, which would often fail to detect rEFItBlesser, thus leaving it enabled and causing rEFInd to fail to start after the first reboot into OS X.</li>
+
+<li><b>0.4.4 (6/23/2012)</b>—This is a bug-fix release. Most importantly, it fixes a bug in the new <tt>use_graphics_for</tt> feature; in 0.4.3, the options were set incorrectly (they just happened to work as expected on my main test configuration). I've also fixed problems with volume names in the 32-bit versions of both the drivers and the TianoCore EDK2 build of rEFInd itself. Finally, I've tweaked the <tt>install.sh</tt> script to do a better job of identifying the computer's ESP under OS X.</li>
+
<li><b>0.4.3 (6/21/2012)</b>—The major user-visible change to this version is the addition of the <tt>use_graphics_for</tt> option, which enables you to specify the OSes that rEFInd launches in graphics mode vs. text mode. This effect is tiny on most systems, but can be important on some, as noted on the <a href="configfile.html">"Configuring the Boot Manager"</a> page. There's also a change to the way graphics-mode boots are handled, to make for a slightly smoother visual transition. This version also fixes the incompatibility between the drivers and the firmware used by Macs (and probably other EFI 1.x systems). I've removed <tt>linux.conf</tt> as a valid alternative name for the <tt>refind_linux.conf</tt> file, so if you're still using the old name, now is the time to rename it! The biggest change is behind the scenes, though: I've added support for compiling rEFInd using the TianoCore EDK2, as well as the GNU-EFI toolkit that I've used up to this point. I have no intention of removing GNU-EFI support, but there's a chance that the TianoCore toolkit will help in implementing some future features or in debugging some problems. You can download either version from the <a href="http://www.rodsbooks.com/refind/getting.html">downloads page.</a></li>
<li><b>0.4.2 (6/3/2012)</b>—I've added a new <tt>dont_scan_dirs</tt> option to the configuration file, enabling creation of a directory-scanning "blacklist." See the <a href="configfile.html">"Configuring the Boot Manager"</a> page for details. This version also makes a couple of changes to the <tt>install.sh</tt> script. The first is a reminder for Mac users to update <tt>refind.conf</tt> if they need to boot BIOS-based OSes. The second change makes the script a bit smarter about updating NVRAM settings when run from Linux; it now attempts to make itself the default boot loader if an entry for rEFInd already exists but isn't the default. I've made this change in response to problem reports from users; apparently some distributions' GRUB update scripts make GRUB the default boot loader under all circumstances, which causes rEFInd to be taken out of the picture after a GRUB update. The previous <tt>install.sh</tt> code wouldn't add rEFInd back to the "top spot" after this happened, but the new code should do the trick. (Although re-installing rEFInd is overkill in this case, it's something many users would logically try.)</li>
