View source for Syslinux 6 Changelog

[[Category:Changelog]]
=== Notes ===
:Since Syslinux 6.00, the respective binary files (e.g. boot loaders,  <!-- 
 --> installers, Syslinux modules,...) are located under respective  <!-- 
 --> "<tt>/bios/</tt>", "<tt>/efi32/</tt>", "<tt>/efi64/</tt>"  <!-- 
 --> subdirectories in the official Syslinux archives.

=== Changes in 6.04 ===
: <span style="color: gray;"> This is a {{nowrap|work-in-progress}},  <!-- 
 --> temporary, {{nowrap|non-exhaustive}}, unfinished list. Items in  <!-- 
 --> this list might change. At the time of writing this temporary list,  <!-- 
 --> version {{nowrap|6.04}} is not yet released; there are no specific plans,  <!-- 
 --> no {{nowrap|road-map}}, no particular {{nowrap|TODO list}}, no ETA.  <!-- 
 --> There are still known bugs, regressions and improvements to be dealt with.  <!-- 
 --> The fact that this temporary list is already included here should  <!-- 
 --> only be interpreted as {{nowrap|potentially useful}} generic information;  <!-- 
 --> the future, {{nowrap|'''<u>unknown</u>''' release date}} for the  <!-- 
 --> official final version {{nowrap|6.04}} is not affected and it is  <!-- 
 --> not closer (nor further) in time. </span>

: <span style="color: maroon;"><u>'''Note''':</u></span> <!--
--> Official Syslinux {{nowrap|6.04-pre2}} and {{nowrap|6.04-pre3}} <!-- 
--> binary files are _not_ recommended for testing.

=== Changes in 6.03 ===
* chain: Fix chainloading on 6.02 (Raphael S. Carvalho).
* core: Do not leak the <tt>__lowmem</tt> and <tt>__bss16</tt> macros to modules; <!--
-->  hide them so modules will not use them.
* load_linux: Do not use size heuristic for non-relocatable <!--
-->  kernels, for zImage kernels and for non-Linux kernels.
* PXELINUX: Fix the SENDCOOKIES feature for HTTP <!--
-->  (Russel Santillanes).
* gnu-efi: Add gnu-efi as a submodule.
* ANSI: Support color tables with more than 256 entries <!--
-->  (James Buren).
* EFI: Fix displayed version; add DATE (Gene Cumm).
* PXELINUX, EFI: Fix bad read of file size over TFTP on EFI64 <!--
-->  (Sylvain Gault).
* Fix hand over to kernel: <br /><!--
-->  "Booting kernel failed: Invalid argument" error.
* ISOLINUX: EDX, LBA values higher than 65535; work around for <!--
-->  buggy BIOS, where the system would hang, would reboot, or <!--
-->  would show a "Disk error 01, AX=42" message.
* core/legacynet: Enable dot quad resolution (Gene Cumm).
* diag/geodsp improvements (Gene Cumm).
* DOS: Fix syslinux.com DOS-based installer.
* Improve gcc 4.3.0 compatibility.
* syslxint: fix compilation on non-x86 architectures.
* localboot: Fix "<code>localboot 0x80</code>" and similar cases.
* Add <tt>memset()</tt> calls prior to any <tt>intcall()</tt> and other mem fixes; <!--
-->  specially relevant for older hardware and/or buggy BIOS.
* poweroff.c32: Fixes (Gene Cumm).
* HDT: Fix memory leak in CLI (Felipe Pena).
* ACPI: Remove memset of buffer; it makes things clearer but <!--
-->  also prevents some compilation warnings (Erwan Velu).
* Add manpages for isohybrid, memdiskfind <!--
-->  (Peter Jones, Gene Cumm).
* ISOLINUX: Experimental Rock Ridge support (Thomas Schmitt).
* comapi: Remove the comapi interfaces.
* EFI: Fixes on PE files and OVMF compatibility <!--
-->  (Sylvain Gault, Gene Cumm).

* Makefiles: Export the firmware type as a cpp variable. <!--
-->  Additional improvements. Fix {{nowrap|"<code>make spotless</code>".}}
* core, BIOS: Move <tt>__syslinux_shuffler_size</tt> to assembly. <!--
-->  Actually get the shuffler size sanely. Fix booting recent <!--
-->  Syslinux versions on certain hardware and on certain <!--
-->  virtualization software (e.g. QEMU 0.11.1, VirtualBox 4.1.x).
* lua: Upgrade to v.5.2.3 (Ferenc Wágner) and additional fixes.
* chainload: Fixes to chain.c32 and pxechn.c32.

=== Changes in 6.02 ===
: <span style="color: maroon;"><u>'''BUG Warning''':</u></span> <!--
-->  Using Syslinux 6.02 on BTRFS volumes corrupts the superblock. <!--
-->  {{nowrap| <big><u>'''Use 6.03 or newer'''</u></big> .}}

* efi64: Add support for booting 32-bit kernels.
* efi: Use the EFI handover protocol when booting kernels if <!--
-->  available.
* Fix various make targets that became broken when switching to <!--
-->  {{nowrap|per-firmware}} object directories, <!--
-->  including {{nowrap|'<code>make install</code>'}} and <!--
-->  {{nowrap|'<code>make netinstall</code>'.}}
* efi: Improve handling of packet loss in UDP stack.
* tests: Introduce a new regression test framework designed to <!--
-->  ensure bugs are not reintroduced once fixed.
* efi: Implement localboot support.

=== Changes in 6.01 ===
* efi: Mark some symbols as __export otherwise libcom32.c32 and <!--
-->  vesamenu.c32 will refuse to load.
* bios: Wire up the bios kernel loader. It was impossible to <!--
-->  load a kernel from bios in 6.00.
* efi: Fix {{nowrap|'<code>make installer</code>'.}} There are no EFI installers so <!--
-->  don't try and build them as we run into build errors.
* efi: Reuse the initial TFTP client port in subsequent <!--
-->  transfers otherwise the server will send an error packet.
* efi: Some firmware will not set a default TTL value in IP <!--
-->  packets - we must explicitly set it ourselves otherwise a <!--
-->  value of zero may be used.
* bios, font: Fix a font regression affecting some VirtualBox <!--
-->  users.

=== Changes in 6.00 ===
* Add support for booting from EFI.
* EFI TCP/IP support. This allows the EFI backend to hook into <!--
-->  the generic TFTP, HTTP and FTP functionality.
