== History ==
The first releases of cdrtools were called cdrecord because they only included the <tt>cdrecord</tt> tool and a few companion tools, but not <tt>mkisofs</tt> nor <tt>cdda2wav</tt>.
In 1997, a copy of <tt>mkisofs</tt><ref>mksofs-1.11 was incorporated to cdrecord-1.5a3 on 5 July 1997 (source: )</ref> (developed at that time by Eric Youngdale) was included in the cdrecord package.
In 1998, a copy of an experimental version of <tt>cdda2wav</tt><ref>cdda2wav-0.95beta07 was incorporated to cdrecord-1.8a6 on 27 October 1998 (source: )</ref> (developed at that time by Heiko Eißfeldt) was included in the cdrecord package.


=== Origins and name change ===
In 2000, Jörg Schilling changed the name of his package from "cdrecord" to "cdrtools"<ref>cdrecord and its friends (mkisofs and cdda2wav) are distributed in a common package called cdrtools since 27 July 2000 (source: ).</ref> to better reflect the fact that it had become a collection of tools.
The first releases of cdrtools were called cdrecord because they only included the <code>cdrecord</code> tool and a few companion tools, but not <code>mkisofs</code> nor <code>cdda2wav</code>. A copy of <code>mkisofs</code>, created in 1993 by Eric Youngdale for ], was incorporated in 1997.<ref>{{cite web |title=Announcing mkisofs 1.13 |url=https://savannah.gnu.org/news/?group_id=10425}}</ref><ref name="SCO">{{cite web |title=CDRTOOLS = cdrecord + cdda2wav + mkisofs |url=http://www.sco.com/skunkware/cdrecord/notes.html}}</ref> In 1998, a copy of an experimental version of <code>cdda2wav</code>, created by Heiko Eißfeldt<ref>{{cite web |title=Cdda2wav |url=http://www.cdda2wav.de/}}</ref><ref name="SCO"/> was included in the cdrecord package.<ref name=cdda2wav>{{cite web |title=cdrecord-1.8a10 (cdrtools) ready |url=https://groups.google.com/g/linux.apps.cdwrite/c/UxtzUM8UqyQ/m/8CVps88BbHAJ }}</ref><ref>{{cite web |title=NEW features of cdrecord-1.8a6 |url=https://ftp.gwdg.de/pub/misc/cdrecord/ALPHA/OLD/1.8aX/AN-1.8a6}}</ref>


In 1999 the project started to be called cdrtools<ref>{{cite web |title=cdrtools-1.8a19 ready (cdrecord+cdda2wav+mkisofs) |url=https://groups.google.com/g/linux.apps.cdwrite/c/FkjzVMWK1w4 }}</ref><ref name="cdda2wav"/><ref>{{cite web |title=Information for build cdrtools-2.01-11.fc7 |url=https://koji.fedoraproject.org/koji/buildinfo?buildID=2185}}</ref> to better reflect the fact that it had become a collection of tools.
Until 2006, cdrtools was the standard and most used software suite in its category on GNU/Linux systems as well as on several other operating systems (mainly BSD-based). It is still the most used{{cn|date=January 2014}} software suite (in its category) on many open source operating systems, '''''except''''' for several major GNU/Linux distributions.


=== DVD and Blu-ray disc writing support ===
== The licensing issue ==
DVD writing support (cdrecord-ProDVD) in cdrecord started in early 1998, at the request of the data archivists of the European Southern Observatory.<ref name="ESO">{{cite web |title=Using DVD Technology for Archiving Astronomical Data |url=https://www.eso.org/sci/publications/messenger/archive/no.93-sep98/messenger-no93-22-23.pdf |publisher=European Southern Observatory}}</ref><ref name="dvd-r">{{cite web |title=The Prospects of DVD-R for Storing Astronomical Archive Data |url=http://adsabs.harvard.edu/pdf/1999ASPC..172..269P7 |publisher=Astronomical Society of the Pacific - Provided by NASA Astrophysics Data System}}</ref><ref name="dvd-rcont">{{cite web |title=Using DVD Technology for Archiving Astronomical Data (cont'd) |url=http://articles.adsabs.harvard.edu/pdf/2000ASPC..216..137P |publisher=Astronomical Society of the Pacific - Provided by NASA Astrophysics Data System}}</ref>{{discuss|ASP paper}} But since the relevant information required a ] and DVD writers were not publicly available, it was not included in the source code.{{cn|date=October 2021}}
In 2002, Jörg Schilling started offering free license keys to the closed-source variant cdrecord-ProDVD for educational, and research use, shortly thereafter also for private use.<ref name="debian mail archive">{{cite web |title=Re: cdrecord floating point exception |url=https://www.mail-archive.com/cdwrite@other.debian.org/msg12603.html}}</ref><ref name="suse"/> Unregistered free licenses were initially limited to single-speed writing and would expire every year.<ref name="suse">{{cite web |title=cdrecord will not burn DVD ISO's |url=https://www.suse.com/support/kb/doc/?id=000016968}}</ref> On 15 May 2006, support for DVD writing was added to the open-source version 2.01.01a09 after switching the license to CDDL; thereby removing the need to get a license key.<ref name="debian mail archive"/><ref name="prodvd">{{cite web |title=README |url=https://ftp.gwdg.de/pub/misc/cdrecord/ProDVD/README}}</ref> Blu-ray disc support was added starting 2007.<ref>{{cite web |title=Changelog |url=https://ftp.gwdg.de/pub/misc/cdrecord/ALPHA/Changelog |language=German}}</ref>


The lack of open-source DVD writing support in 2001 led to heated discussions on the mailing lists,<ref name="debian mail archive"/> and to a number of unofficial patches for supporting the Pioneer DVD-R A03, the first DVD writer to reach mass market, and forks of cdrecord: Mandrake shipped a version called cdrecord-dvdhack,<ref>{{cite web | url=http://www.mandriva.com/de/support/security/advisories/8.2/MDKA-2002:011-1/ | title=Support / Security / Advisories / Mandrakelinux 8.2 / MDKA-2002:011-1 / Mandriva | publisher=] | accessdate=2014-10-16 | quote=cdrecord-dvdhack-1.11-0.a31.1.1mdk.ppc.rpm}} shows that Mandrake maintained a "cdrecord-dvdhack" version.</ref> whereas Redhat had dvdrecord.<ref>{{cite web|url=http://www.nongnu.org/dvdrtools/ |title=dvdrtools - dvdrecord |accessdate=2014-04-12 |url-status=dead |archiveurl=https://web.archive.org/web/20021201160106/http://www.nongnu.org/dvdrtools/ |archivedate=1 December 2002 |df=dmy }}</ref>
The project was originally licensed under the ] (GPL).


=== Hardware access controversy ===
With version 1.11a17 (released in 2002), a section of cdrtools' ] was modified to include an ], with the intent to prevent people from distributing variants with intentional bugs under the original name.<ref>See the file LIMITATIONS</ref> The purpose of this invariant section was to make sure any modification to cdrecord would be properly reported as such to the user. Publishing modified code under another name is still permitted, making the file compatible with the OpenSource definition and specific licenses like the GPL.<ref>], ] and ] are a few examples of open source software that put conditions on their licenses regarding source code changes. (Source: "Trademark and OSS" at )</ref>
Unlike ] and ], which use ]s to access the ], cdrtools uses a different method known as CAM (for Common Access Method),<ref>{{cite web |url=http://standards.incits.org/apps/group_public/project/details.php?project_id=260 |title=Common Access Method Transport and SCSI Interface Module |date=29 December 2011 |publisher=] |accessdate=2016-01-24 }}</ref> which is available on many operating systems, including some which lack device files or only allow the kernel to access them.
<!-- Snippet of the invariant section in cdrecord.c :
This difference has turned into a controversy: some Linux users claim that the method used by cdrtools is not appropriate, while some Linux users claim that the users of cdrtools do not need to know which method is used.{{citation needed|date=April 2018}}

In cdrtools, burning optical media (such as CDs, DVDs and Blu-rays discs) is done through the ] interface. Users of systems with more than one burning device need to provide a SCSI device (which is identified by a triplet of numbers, <code>scsibus,target,lun</code>). Users of systems with only one burning device, however, do not need to specify the SCSI device since cdrtools is able to find it. By 2002 more and more burners were using the ] interface. Linux 2.6 allowed the users to detect the SCSI ID of a device from its UNIX device path (<code>/dev/hdX</code>) and a patch was published that made identifying the burner device for cdrecord simpler by allowing the user to specify the <code>/dev/hdX</code> device name (or even default to a ] managed link such as <code>/dev/cdrw</code>). Schilling, however, rejected this approach as well as other modifications used by Linux distributions, with the rationale that it would make the software more complex and less portable as this function was not available on other UNIX systems.<ref name="lwn-middleman" /> ] states that SCSI LUNs should not be used for addressing devices on Linux,<ref name="linus-lun">{{cite web |url=https://lkml.org/lkml/2006/3/27/129 |title=Re: Move SG_GET_SCSI_ID from sg to scsi |last1=Torvalds |first1=Linus |authorlink1=Linus Torvalds |date=2006-03-27 |website=] |access-date=2015-10-22 |quote=the SCSI ID simply doesn't make sense to and they have none.

Instead Torvalds recommends that devices should be addressed via their UUID, physical connection, or an alias symlink<ref name="linus-lun2">{{cite web | url=https://lkml.org/lkml/2006/3/27/117 |title=Re: Move SG_GET_SCSI_ID from sg to scsi |last1=Torvalds |first1=Linus |authorlink1=Linus Torvalds |date=2006-03-27 |website=] |access-date=2015-10-22}}</ref> as managed by ] on Linux.
In May 2006, most parts of cdrtools were switched to the ] with permission from their authors.<ref name="license change">The license change took place on 15 May 2006, when cdrtools-2.01.01a09 was released. (Source: )</ref>
Torvalds pointed out that the ioctl's have been kept to ensure cdrecord compatibility<ref name="linus-lun3">{{cite web | url=https://lkml.org/lkml/2006/3/27/129 |title=Re: Move SG_GET_SCSI_ID from sg to scsi|last1=Torvalds |first1=Linus |authorlink1=Linus Torvalds |date=2006-03-27 |website=] |access-date=2015-10-22 | quote=it does a few ioctl's that cdrecord wanted does NOT try to claim that those numbers "mean" anything BUS/ID/LUN crap really doesn't make sense for the majority of devices out there.

After this license change some parts of cdrtools (e.g. <tt>mkisofs</tt>, which is still GPL-licensed) use code that was switched to CDDL, (e.g. <tt>libscg</tt>, the ] Transport Layer developed by Jörg Schilling).


=== License compatibility controversy ===
According to the ], the CDDL is ] with the ] (GPL).<ref name="fsf">{{cite web|url=http://www.gnu.org/licenses/license-list.html#SoftwareLicenses|title=Various Licenses and Comments About Them - Common Development and Distribution License|publisher=Free Software Foundation|accessdate=2006-12-31}}</ref>
By 2004, Linux distributions were maintaining a number of unofficial changes{{snd}} such as allowing the use of <code>/dev/hdX</code> device names and (limited) DVD writing support{{snd}} that were rejected by Schilling,<ref name="lwn-middleman">{{cite web | url = https://lwn.net/Articles/97469/ | first = Jonathan | last = Corbet | title = The value of middlemen | publisher=] | date=2004-08-11 | accessdate = 2014-04-07}}</ref> who repeatedly demanded that distributions stop shipping "bastardized and defective" versions of his "legal original software".<ref name="Corbet2">{{cite web |url=https://lwn.net/Articles/346540/ |title=The unending story of cdrtools |last1=Corbet |first1=Jonathan |date=2009-08-12 |publisher=] |accessdate=26 February 2014}}</ref>
Jonathan Corbet, founder of the ] news source argued this makes it impossible to legally distribute cdrtools binaries.<ref>{{cite web | url = http://lwn.net/Articles/195167/ | author = Jonathan Corbet | title = cdrtools - a tale of two licenses | accessdate = 2007-08-04 }}</ref>
Starting with version 2.01.01a09 in May 2006, most code from cdrtools has been ] under the ], while mkisofs remains licensed under the ].<ref name="license change">The license change took place on 15 May 2006, when cdrtools-2.01.01a09 was released. (Source: )</ref> This change led to an ongoing disagreement about whether distribution or use of precompiled cdrtools binaries is legally possible (the GPL permits ]s, but not derivative works; and the Makefiles used to build mkisofs are CDDL licensed). The following are one-sentence summaries of the different positions:
Other observers claim that this license issue could be solved by using dynamic-link libraries (also called shared objects), that is, code under the GPL license may use code under the CDDL license (and vice-versa) as long as the codes are stored in distinct files (one runtime and one or more shared objects).{{cn|date=January 2014}}
* Jonathan Corbet, founder of the ] news source argued that this change makes it impossible to legally distribute cdrtools binaries, because the build system used is CDDL licensed (interpreting cdrtools as derivative work of GPL and – GPL-] – CDDL code) and the GPL requires "build tools and scripts also be released under the GPL".<ref name="tale">{{cite web |url=https://lwn.net/Articles/195167/ |first=Jonathan |last=Corbet |title=cdrtools - a tale of two licenses |publisher=] |accessdate=2007-08-04}}</ref> <!-- Eben Moglen should be added here too, I guess -->
* Jörg Schilling denied there was a license problem in cdrtools. In his interpretation, it consisted of independent works and thus has not mixed incompatible licenses (i.e. it is a collective work, not a derivative work). According to his interpretation, binary versions may be distributed.<ref name="joerg-no-problem">{{cite web | url=https://bugs.launchpad.net/ubuntu/+source/cdrtools/+bug/213215/comments/17 | date=2011-06-27 | title=Comment 17 for bug 213215 | publisher=Ubuntu bug tracking | first=Joerg | last=Schilling | quote=Nobody is violating a license for distributing cdrtools either in source or in binary form.}}</ref>
* Fedora says the cdrtools is a "incompatible mix of the GPL and the CDDL"<ref name="forbidden">{{cite web|url=https://fedoraproject.org/Forbidden_items|title=Forbidden items - FedoraProject|website=fedoraproject.org}}</ref> and Schilling's opinion is a "set of unorthodox opinions on licensing which are not shared by the FSF or Red Hat Legal"<ref name="forbidden"/> and thus cdrtools is forbidden on Fedora.
* Fedora's legals also proposed three solutions to solve license incompatibility (adding some sort of ], replace CDDL with GPL-compatible license, or dual-licensing CDDL/GPL<ref name="fedoradiscussion">{{Cite web|url=https://www.redhat.com/archives/fedora-legal-list/2009-July/msg00000.html|title=Re: Legal CD/DVD/BD writing software for RedHat and Fedora|website=www.redhat.com}}</ref>) and consequently available to re-open discussion about including cdrtools.
* As is ] and other open source licenses, very little case law exists to provide guidance to users and provide a definitive answer on whether binary versions are distributable.


As a result of this controversy:
Because of this alleged license issue, several GNU/Linux distributions stopped distributing cdrtools in 2006.

=== Inclusion into toolset Schily-Tools ===
The author's position is that any open source operating system can distribute cdrtools as long as the terms of the licenses are respected.<ref>cdrtools may be distributed in source and/or binary form, as indicated in file "COPYING" of any recent source tarball, (e.g. for the current stable release).</ref><ref>See in .</ref>
Cdrtools are part of Jörg Schilling's toolset Schily-Tools which was originally distributed on ].<ref>"The official Shily-Tools project website:" http://schilytools.sourceforge.net/</ref>


Schilling stopped updating the cdrtools-only alpha and stable branch in 2017 with version 3.02a9;<ref>{{Cite web|url=https://sourceforge.net/projects/cdrtools/files/alpha/README/view|title=cdrecord &#124; Release notes for cdrecord at SourceForge.net|website=sourceforge.net}}</ref> version 3.02a10 and higher are only included in the source package schilytools.
In September 2006, four months after the license change, Jörg Schilling added support for dynamic-linking cdrtools,<ref name="support for dynamic link added">Support for dynamic-link libraries was added to cdrtools on 18 September 2006, when cdrtools-2.01.01a15 was released (source: )</ref> hoping this would be enough for the GNU/Linux distributions to restart distributing cdrtools.


The "Schily" Tool Box is a set of tools written or managed by Jörg Schilling. It includes the programs: cdrecord, cdda2wav, readcd, mkisofs, smake, bsh, btcflash, calc, calltree, change, compare, count, devdump, dmake based on SunPro Make, hdump, isodebug, isodump, isoinfo, isovfy, label, mt, obosh, od, p, POSIX patch, pbosh, ], scgcheck, scpio, sdd, sfind, sformat, smake, sh/bosh (Bourne sh), star, star_sym, strar, suntar, gnutar, tartest, termcap, and ved.

Xorriso and the associated software in libisoburn is almost capable of replacing all the aging cdrtools-derived software that we have in Debian, The only missing feature that I’m aware of is creating the HFS hybrid filesystems that we use for installations on Mac systems. I’ve been talking with the upstream folks about this for some time already, and I’m hoping we can finish this soon enough that we can get it into Wheezy."

Many operating system vendors, but not all, do distribute cdrtools.
Because some major GNU/Linux distributions do not, several dedicated individuals have decided to help the community by providing unofficial builds of cdrtools.
This table lists some popular operating systems, as well as some GNU/Linux distributions that ship cdrtools.

cdrtools (formerly known as cdrecord) is a collection of independent projects of free software/open source computer programs for CD and DVD authoring.

The project was maintained for over two decades by Jörg Schilling, who died on October 10, 2021.

Because of some licensing issues, there is also a Debian fork of an older version of cdrtools called cdrkit.

Features

The most important parts of the package are cdrecord, a console-based burning program; cdda2wav, a CD audio ripper that uses libparanoia; and mkisofs, a CD/DVD/BD/UDF/HFS filesystem image creator. As these tools do not include any GUI, many graphical front-ends have been created.

The collection includes many features for CD, DVD and Blu-ray disc writing such as:

History

Origins and name change

The first releases of cdrtools were called cdrecord because they only included the cdrecord tool and a few companion tools, but not mkisofs nor cdda2wav. A copy of mkisofs, created in 1993 by Eric Youngdale for Yggdrasil Linux, was incorporated in 1997. In 1998, a copy of an experimental version of cdda2wav, created by Heiko Eißfeldt was included in the cdrecord package.

In 1999 the project started to be called cdrtools to better reflect the fact that it had become a collection of tools.

DVD and Blu-ray disc writing support

DVD writing support (cdrecord-ProDVD) in cdrecord started in early 1998, at the request of the data archivists of the European Southern Observatory. But since the relevant information required a non-disclosure agreement and DVD writers were not publicly available, it was not included in the source code. In 2002, Jörg Schilling started offering free license keys to the closed-source variant cdrecord-ProDVD for educational, and research use, shortly thereafter also for private use. Unregistered free licenses were initially limited to single-speed writing and would expire every year. On 15 May 2006, support for DVD writing was added to the open-source version 2.01.01a09 after switching the license to CDDL; thereby removing the need to get a license key. Blu-ray disc support was added starting 2007.

The lack of open-source DVD writing support in 2001 led to heated discussions on the mailing lists, and to a number of unofficial patches for supporting the Pioneer DVD-R A03, the first DVD writer to reach mass market, and forks of cdrecord: Mandrake shipped a version called cdrecord-dvdhack, whereas Redhat had dvdrecord.

Hardware access controversy

Unlike cdrkit and libburnia, which use device files to access the hardware, cdrtools uses a different method known as CAM (for Common Access Method), which is available on many operating systems, including some which lack device files or only allow the kernel to access them. This difference has turned into a controversy: some Linux users claim that the method used by cdrtools is not appropriate, while some Linux users claim that the users of cdrtools do not need to know which method is used.

In cdrtools, burning optical media (such as CDs, DVDs and Blu-rays discs) is done through the SCSI interface. Users of systems with more than one burning device need to provide a SCSI device (which is identified by a triplet of numbers, scsibus,target,lun). Users of systems with only one burning device, however, do not need to specify the SCSI device since cdrtools is able to find it. By 2002 more and more burners were using the ATAPI interface. Linux 2.6 allowed the users to detect the SCSI ID of a device from its UNIX device path (/dev/hdX) and a patch was published that made identifying the burner device for cdrecord simpler by allowing the user to specify the /dev/hdX device name (or even default to a udev managed link such as /dev/cdrw). Schilling, however, rejected this approach as well as other modifications used by Linux distributions, with the rationale that it would make the software more complex and less portable as this function was not available on other UNIX systems. Linus Torvalds states that SCSI LUNs should not be used for addressing devices on Linux, because these numbers are not unique, and do not make sense for many devices anymore (many devices will report 0:0:0 fake numbers). Instead Torvalds recommends that devices should be addressed via their UUID, physical connection, or an alias symlink as managed by udev on Linux. Torvalds pointed out that the ioctl's have been kept to ensure cdrecord compatibility and do not return a meaningful value.

License compatibility controversy

By 2004, Linux distributions were maintaining a number of unofficial changes – such as allowing the use of /dev/hdX device names and (limited) DVD writing support – that were rejected by Schilling, who repeatedly demanded that distributions stop shipping "bastardized and defective" versions of his "legal original software". Starting with version 2.01.01a09 in May 2006, most code from cdrtools has been relicensed under the CDDL, while mkisofs remains licensed under the GPL. This change led to an ongoing disagreement about whether distribution or use of precompiled cdrtools binaries is legally possible (the GPL permits collective works, but not derivative works; and the Makefiles used to build mkisofs are CDDL licensed). The following are one-sentence summaries of the different positions:

  • Jonathan Corbet, founder of the LWN.net news source argued that this change makes it impossible to legally distribute cdrtools binaries, because the build system used is CDDL licensed (interpreting cdrtools as derivative work of GPL and – GPL-incompatible – CDDL code) and the GPL requires "build tools and scripts also be released under the GPL".
  • Jörg Schilling denied there was a license problem in cdrtools. In his interpretation, it consisted of independent works and thus has not mixed incompatible licenses (i.e. it is a collective work, not a derivative work). According to his interpretation, binary versions may be distributed.
  • Fedora says the cdrtools is a "incompatible mix of the GPL and the CDDL" and Schilling's opinion is a "set of unorthodox opinions on licensing which are not shared by the FSF or Red Hat Legal" and thus cdrtools is forbidden on Fedora.
  • Fedora's legals also proposed three solutions to solve license incompatibility (adding some sort of GPL linking exception, replace CDDL with GPL-compatible license, or dual-licensing CDDL/GPL) and consequently available to re-open discussion about including cdrtools.
  • As is common with the GPL and other open source licenses, very little case law exists to provide guidance to users and provide a definitive answer on whether binary versions are distributable.

As a result of this controversy:

  • Debian, Red Hat, Fedora and Ubuntu dropped the versions of cdrtools with CDDL code from their distributions and switched to the Debian project created cdrkit, a fork of the last GPL-licensed cdrtools version.
  • Jörg Schilling continued to develop his version of cdrtools under the CDDL and GPL (mkisofs) licenses until he died in 2021, whereas the cdrkit fork has received next to no updates since Cdrkit 1.1.11, which was released in 2010.
  • Independent development efforts happen in libburnia which does not contain cdrtools source code, but includes a wrapper "cdrskin" to offer some command line compatibility with cdrecord and is available in many Linux distributions.
  • Gentoo Linux is unaffected, as the potential licensing issue only affects the distribution of precompiled binaries and this distribution compile from source code. It initially offers both versions, as well as libburnia, dropping cdrkit in 2017.
  • Slackware only provided cdrtools (build script for cdrkit is available from SlackBuild.org, but the two packages could not co-exists); libburnia was introduced in November 2020 as needed by KDE Plasma 5.
  • Mandriva Linux, which had dropped its cdrtools package in 2007, was returned by Mandriva to the community and became OpenMandriva Lx, which ships the original cdrtools.
  • openSUSE, which had dropped its customized cdrtools package in 2007, added back the original cdrtools in Fall 2013.
  • Since building cdrtools from source is widely accepted as legal, there exist compile instructions for many Linux distributions.

Inclusion into toolset Schily-Tools

Cdrtools are part of Jörg Schilling's toolset Schily-Tools which was originally distributed on SourceForge.

Schilling stopped updating the cdrtools-only alpha and stable branch in 2017 with version 3.02a9; version 3.02a10 and higher are only included in the source package schilytools.

The "Schily" Tool Box is a set of tools written or managed by Jörg Schilling. It includes the programs: cdrecord, cdda2wav, readcd, mkisofs, smake, bsh, btcflash, calc, calltree, change, compare, count, devdump, dmake based on SunPro Make, hdump, isodebug, isodump, isoinfo, isovfy, label, mt, obosh, od, p, POSIX patch, pbosh, sccs, scgcheck, scpio, sdd, sfind, sformat, smake, sh/bosh (Bourne sh), star, star_sym, strar, suntar, gnutar, tartest, termcap, and ved.

The final version of Schily-Tools published by Jörg Schilling himself is the 2021-09-18 release. After his death, development of Schily-Tools has been taken up by a group of volunteers. Instead of hosting it on SourceForge, it is hosted on a-not-for-profit platform, Codeberg. To mark his passing, his cdrtools final version, 3.02a10 (where the a indicates the software is semantically alpha) was declared to be the new stable version 3.02 with no substantial changes.
