November 2013 -- Highlights

A new page, "RFC Status Changes", has been released that lists the RFCs whose statuses have changed since publication. The list indicates the date of the status change and links to the Document or Protocol Action or the RFC requesting the change are provided where possible.

In addition, the RFC Editor is retiring the practice of publishing RFCs xx99, the Request for Comments Summary for RFC Numbers xx00-xx99 because this information is readily available online (e.g., search results). RFC numbers typically reserved for these documents (i.e., numbers ending with 99) may be assigned to future RFCs. See the message to the IETF Announce list and the discussion on the RFC Interest list for more information (October and November mail).

March 2013 -- Highlights

On 14 March 2013, the IAB approved for publication the RFC Series Format Requirements and Future Development draft. This document sets the current requirements and direction for the format of RFCs and indicates that there will be changes forthcoming to both the traditional 100% ASCII format as well as to the RFC Style Guide.

January 2013 -- Highlights

2012 was a intense year of progress and change for the RFC Editor. With a new RFC Series Editor, a revival of the RFC Format discussion, several changes to the RFC Editor website, the beta rollout of a new search page, and 338 RFCs published, the RFC Editor is picking up the pace for an even more intense 2013. 2013 starts with final comments being received on the RFC Format Requirements draft and ramp up of the work on the Style Guide.

September 2012 -- Highlights

The RFC Series Format Development draft describing the requirements for changes in the format for RFCs has been posted. Discussions regarding the requirements will ooccur on the rfc-interest mailing list and at a BoF at IETF #85.

February 2012 -- Highlights

The focus this month, updating information on Copyright. See RFC Copyrights & IPR and RFC Editor Guidelines and Procedures.

23 February 2010 -- New Email Address for Independent Submission Stream

A new mail list was created to handle email that is specifically related to the Independent Submission stream process (rfc-ise@rfc-editor.org).

See the related announcement for more information.

http://www.rfc-editor.org/pipermail/rfc-interest/2010-February/001729.html

2 February 2010 -- De-commit of SMTP-based RFC Retrieval Service

Even before the Web was invented, ISI offered an SMTP-based online search and retrieval service. With a few software patches over the years, this now rather crufty Perl code has continued to provide service.

However, maintenance of this very old code is not feasible, so ISI and AMS did not attempt to transition it to AMS. The RFC Editor has decided to de-commit the rfc-info service. It is rare today that a user does not have access to a web browser. However, the rfc-info mailbox has been redirected to rfc-editor@rfc-editor.org, and Production House staff will respond to email to the old address.

11 January 2010 -- RFC Editor Transition Will Take Place on 12 January 2010

Transition from USC/ISI to AMS will take place on 12 January 2010. During this time, the static RFC Editor pages at rfc-editor.org will continue to be available, including RFC and errata search and retrieval. However, the errata submission and verification portals will be temporarily disabled. Additionally, email sent to the RFC Editor will not be read or processed until after the transition is complete. For more information, please see the announcement available at http://www.ietf.org/ibin/c5i?mid=6&rid=49&gid=0&k1=934&k2=7324&tid=1263251951.

28 December 2009 -- TLP 4.0 Announced; Updated to Account for Non-IETF Stream Documents

The IETF Trust has adopted a new version of the Trust Legal Provisions (TLP 4.0), which addresses the requests from the RFC Editor (RFC 5744), the IRTF (RFC 5743), and the IAB (RFC 5745) for the Trust to manage the outgoing rights for documents originating in their streams.

The approval of TLP 4.0 allows for the Independent and the IRTF stream documents to be published. The RFC Editor will be working to update the files accordingly and will contact the authors when the updated documents can be viewed.

24 December 2009 -- RFC 5741, RFC Streams, Headers, and Boilerplates

With the publication of RFC 5741, the headers and boilerplate material for each document has changed. RFC document headers will now indicate the stream that originated the document, and the Status of This Memo will indicate the level of review associated with the document. Julian Reschke has put together a document that details the various combinations; please see http://greenbytes.de/tech/webdav/draft-reschke-hab-05.html.

29 July 2009 -- Publication of Independent and IRTF Stream Documents

The publication of Independent and IRTF stream documents continues to be suspended while the streams work with the Trust to identify the appropriate copyright for these documents.

1 July 2009 -- Placement of the Abstract in RFCs

As of 1 July 2009, the RFC Editor is publishing RFCs with the abstract placed between the title and the Status of This Memo. For more details, see our announcement at
http://mailman.rfc-editor.org/pipermail/rfc-interest/2009-June/001373.html.

15 February 2009 -- Revised "Legal Provisions Relating to IETF Documents"

On 12 February 2009, the IETF Trust announced a revision to the "Legal Provisions Relating to IETF Documents", effective 15 February 2009, which contains optional text in Section 6.c.iii to address the issue of pre-RFC 5378 material. Please review RFC 5378 and the text located at http://trustee.ietf.org/license-info/. The RFC Editor will update the copyright notice and legends of documents in our queue accordingly.

For more information regarding the copyright notice and legends, please see the discussion at ietf@ietf.org. Also, you can send copyright questions to copyright-questions@ietf.org.

Independent Submissions publications are on hold until the RFC Editor has made a decision regarding the copyright to be applied to Independent stream documents. This is in progress and we expect to have this issue resolved shortly.

15 January 2009 -- RFC Publication Resumed

The publication of BCP 78/RFC 5378 has caused some transitional issues that require the RFC Editor to temporarily suspend publication. The RFC Editor is only publishing RFCs if each author explicitly approves the RFC 5378 copyright notice and legends. If the authors cannot agree to the terms of the RFC 5378 copyright notice and legends, the document will be placed on hold until the issues have been resolved.

06 January 2009 -- RFC Publication Suspended

The publication of BCP 78/RFC 5378 has caused some transitional issues that require the RFC Editor to temporarily suspend publication. We are working with the appropriate parties to determine the process moving forward. We will provide an update shortly and an email to explain the proper process.

10 November 2008 -- Legal Provisions Relating to IETF Documents

With the publication of BCP 78/RFC 5378, "Rights Contributors Provide to the IETF Trust", the RFC Editor has adopted a new IETF copyright policy. The RFC Editor will now include the following Copyright Notice, which will appear on the front page of RFCs:

   Copyright (c) YYYY IETF Trust and the persons identified as the
   document authors.  All rights reserved.

   This document is subject to BCP 78 and the IETF Trust's Legal
   Provisions Relating to IETF Documents
   (http://trustee.ietf.org/license-info) in effect on the date of
   publication of this document.  Please review these documents
   carefully, as they describe your rights and restrictions with
   respect to this document.

The Full Copyright Statement, which was the standard last page of an RFC, will no longer be included in RFCs.

Please see Legal Provisions Relating to IETF Documents for more details.

Additionally, Independent Submissions publications are on hold until the RFC Editor has made a decision regarding the copyright to be applied to Independent stream documents. This is in progress and we expect to have this issue resolved shortly.

1 October 2008 -- ISSN Number

The RFC series has now been assigned a universal ISSN number, bringing it into the world of librarians. This number is displayed on the main web page.

1 October 2008 -- New Queue Display File

The file queue.html is updated daily to display the current "Publication queue" button on the main web page. We recently created a new version of this queue, file queue2.html (http://www.rfc-editor.org/queue2.html). Its major new features are:

The "Publication Queue" link on the main page now points to queue2.html. However, we intend to maintain queue.html as well as queue2.html, so that queue.html can be a stable source for "screen scrapers".

Corresponding to the new queue2.html, there is also a queue2.xml. This differs from queue.xml in tag changes to more accurately reflect component semantics. Additional informartion may be added to queue2.html, .xml in the future.

12 November 2007 -- RFC Errata System

The RFC Editor has transitioned to a new errata system, which allows for online errata submission. Please see:

http://www.rfc-editor.org/errata.php

The records have been updated to include all reports from the pending file.

The process allows for SSPs (stream-specific parties) to edit, verify, or reject reports using an online verification system.

21 August 2007 -- Changes to RFC Boilerplate

With the approval of the IAOC, the RFC Editor will make two minor changes (deletions) from the standard RFC boilerplate in future RFC publications.

First, the "Copyright (C) The IETF Trust" declaration will be removed from the front page of future RFCs. We have known for a long time that this declaration is redundant with the complete boilerplate at the end of the documents, but inertia kept it alive. Second, the funding acknowledgment to the Internet Society at the end of the document will be removed. This acknowledgment was added around 1998 when funding shifted from US Government to the Internet Society, and at a time when the Internet Society was not yet closely linked into the IETF community. Much has changed since then, including the establishment of the IAOC and the IAD. The funding acknowledgment no longer seems necessary, and it will be dropped from future RFCs.

15 March 2007 -- Intellectual Property Rights RFCs

In October 2006, the RFC Editor published RFC 4748 as an update to RFC 3978, which concerns RFC copyrights. Together, these documents form BCP 78.

RFC 3978 obsoletes RFC 3667 as BCP 78. The revisions incorporate very minor changes in the boilerplate to recognize the IETF Trust. The RFC Editor's copyright web page was updated accordingly. This web page also has links to previous versions of the RFC Editor copyright rules.

15 December 2006 -- New RFC Editor Web Pages

As we have added new material over the past 8 years, the RFC Editor web site has grown increasingly confusing. We have now updated the main page and several of the subsidiary pages. The result should be to make the more important information immediately available and to make it easier to find what you want. Please address comments and suggestions to us at rfc-editor@rfc-editor.org.

12 November 2006 -- Joyce Reynolds Departs
The RFC Editor is saddened by the departure of Joyce Reynolds from the RFC Editor staff. She has left ISI to take on a new and challenging job assignment elsewhere. The brass ring came by, and she grabbed it!

Over many years, Joyce has made major contributions to the IANA, to the RFC Editor, and to the IETF.

She worked with Jon Postel to perform the IANA functions, leaving her name on many related RFCs. She was IANA liaison to the IESG 1998-2001 and consulted with IANA after they separated from ISI. She played a key early role in shaping the protocol parameter registration function.

Joyce has been a member of the IETF since 1988. She developed, organized, and led the User Services area of the IETF from 1988-1998, and was thus an IESG member. In her User Services role, she was an international keynote speakder and panelist in over 90 conferences around the world, spreading the word on the Internet. She established the user-service oriented document subseries of RFCs, the FYIs. She worked with Jon on documenting a number of protocol specifications, including POP, FTP, and Telnet Options.

For a number of years, Joyce worked with Jon Postel on editing RFCs. Since 1998, she has been co-leader of the RFC Editor function, and she performed the final quality control function on most RFC publications. She also served as RFC Editor liaison to the IAB and to the IESG. Her knowledge of the IETF process and community and her good judgment were immensely helpful, and we will miss her help and advice a great deal.

We expect that Joyce will still have a presence in the IETF, but she will be much missed at ISI! We know that Jon Postel joins us in wishing her the very best future in her new job.

8 June 2006 -- New Rules for Independent Submissions
These web pages and various RFCs explain that the RFC Editor publishes two classes of documents: IETF documents and independent submissions. In the past, editorial responsibility for independent submissions has resided with the RFC Editor, in consultation with the RFC Editorial Board and limited by the need for consistency with the IETF standards process. Under IAB leadership, the IETF community is now undertaking to redefine the rules for RFC independent submissions. The IAB has made the following announcement:

   As part its role in supporting the RFC Editor function, the Internet
   Architecture Board (IAB) has created a public mailing list for the
   discussion of the RFC Independent Submissions process.

   The purpose of this discussion is to achieve consensus, in the coming
   weeks, on a process for fair and appropriate approval of independent
   submissions to the RFC series.  These are separate from IETF, IAB or
   IRTF approved submissions.

   Individuals familiar with the RFC series and working in the Internet
   research and engineering community are invited to join this mailing
   list and participate.

      independent < at > ietf.org

      http://www1.ietf.org/mailman/listinfo/independent

   There is an initial draft proposal, available at

      http://www.ietf.org/internet-drafts/draft-klensin-rfc-independent-02.txt

17 January 2006 -- State Change Messages to Authors
The RFC Editor has added a new informational service to authors. Whenever a document enters the editorial queue, changes its state in the queue, or leaves the queue, an email message summarizing the state change is now being sent automatically to the authors. This message is for information only; it does not replace existing messages to authors, such as AUTH48 messages.

Here are examples of such messages:

    The document draft-ietf-sipping-conferencing-framework-05
    has hanged from EDIT*R state to RFC-EDITOR state.

    The document draft-ietf-avt-uncomp-video-ext-01 has
    changed from EDIT*A state to EDIT state.

If present, the suffix "*A" in the state listed in this message means: "IANA actions are needed". This is an encoding of the keyword "IANA" in the queue entry for the Draft.

If present, the suffix "*R" in the state listed in this message means: "Contains one or more normative references to drafts that are not yet published." Any such references are detailed after the keyword "REF" in the queue entry for the Draft.

15 November 2005 -- Errata Processing Delayed
At the present time, the RFC Editor is concentrating our efforts on reducing the editing backlog. One of the tasks we are unable to perform as a result is processing and posting new errata items on the Errata page. Since some reported errata items are important, we have put online the mbox mail file containing the recent email correspondence about claimed errata. The errata in these messages have not been verified or posted, and they will not be found by links from the search engine.

6 October 2005 -- Queue Generated Automatically
On September 27, the RFC Editor installed a program to automatically generate the publication queue file daily from our master database. The queue file had been maintained manually, which sometimes led to errors. Our intent in this change was that users should see no differences (except for lack of errors), but of course there were some initial glitches. Please notify us of problems with the new queue.

One feature has been added to the queue: each normative reference entry ("REF") now indicates whether the referenced document is in the queue. Our current policy is to not begin editing a document until all its normative references are also in the queue (or already published, of course). For example, the following partial entry shows a document in the EDIT state with two unpublished Normative references, one of which has not been received by the RFC Editor:

2005-03-31      draft-ietf-simple-event-filter-funct-05.txt
EDIT
REF     draft-ietf-simple-event-list    NOT-RECEIVED
        draft-ietf-simple-filter-format IN-QUEUE

16 August 2005 -- Recently Published RFCs
The RFC Editor web page now lists the twelve most recently published RFCs (Click on: "Recent RFCs" at www.rfc-editor.org).

31 July 2005 -- RFC Editor Tutorial
The RFC Editor gave a tutorial for RFC authors at IETF 63 (Paris). This presentation included an overview of the RFC series, RFC contents, RFC publication procedures, and hints to authors.

1 March 2005 -- Intellectual Property Rights RFCs
On March 1, 2005, the RFC Editor published two RFCs concerning RFC copyrights and patent rights: RFC 3978 and RFC 3979.

RFC 3978 obsoletes RFC 3667 as BCP 78, and RFC 3979 obsoletes RFC 3668 as BCP 79. The revisions incorporate very minor changes in boilerplate. The RFC Editor's copyright web page was updated accordingly. This web page also has links to previous versions of the RFC Editor copyright rules.

23 February 2005 -- Update Process Diagram
The RFC Editor publication process diagram has been updated to more accurately reflect the current process. Significant changes are: (1) to show a new state ISR-AUTH for independent submissions, and (2) to show that IANA processing and RFC Editor processing take place in parallel, not sequentially.

28 July 2004 -- RFC Bibliographic Entry File
A file is now available containing a listing of bibliographic entries for all RFCs, in the reference format preferred by the RFC Editor. It also shows which RFCs have been obsoleted.

31 March 2004 -- Hyperlinks within Queue
We've added HTML anchors to entries in the RFC Editor queue, to allow linking directly to the queue entry for a document of interest. The URL will be:

http://www.rfc-editor.org/queue.html#draft-name

where "draft-name" is the stem of the Internet Draft name, without the version number or .txt suffix. For example, try:

http://www.rfc-editor.org/queue.html#draft-ietf-sip-referredby

31 March 2004 -- Errata Linked from Search Results
The RFC Editor's RFC search engine is now linked to our Errata data base. In a search result line, the "More Info" field, in addition to Obsoletes and Updates entries, will have an "Errata" hyperlink for any RFC for which a correction has been noted. Clicking on that link will take you directly to the Errata entry for that RFC.

EG try searching for 3885.

15 March 2004 -- RFC Interest List
The RFC Editor has created a new mailing list, rfc-interest@rfc-editor.org.

This list was created to facilitate community discussion on the RFC series and to make suggestions about RFC Editor functions. The RFC Editor hopes that this mailing list will provide a focal point for input, information, and discussion about the details of the RFC process, as well as an archive to avoid the continual re-hashing of some issues. Topics appropriate to this list may include formatting, tools, style, content, and indexing aspects of the RFC series. It will not be used for discussion of the IETF standards process, general IETF organizational issues, or issues for which the NOTE WELL admonition is needed for IPR reasons. The posting policy is subscriber-only to reduce spam. It will initially be unmoderated, but the RFC Editor will cut off any discussions that are inappropriate according to the guidelines above. Subscribe at the following address:

       http://www.rfc-editor.org/mailman/listinfo/rfc-interest

Archives are available at:

       http://www.rfc-editor.org/pipermail/rfc-interest/

18 February 2004 -- Intellectual Property RFCs
Today the RFC Editor published two RFCs that clarify and elaborate the rules for copyrights on RFCs as well as the RFC boilerplate for intellectual property rights. This change was developed by the IPR working group and adopted by community consensus. The RFCs are "IETF Rights in Contributions", RFC 3667 (BCP 78) and "Intellectual Property Rights in IETF Technology", RFC 3668 (BCP 79). Beginning today, the RFC Editor will use the new rules for all RFC publication.

For the implications of these new rules for RFCs, see the new RFC Editor web page.

10 December 2003
The RFC Editor has upgraded the rsync server based on this advisory. Instructions for using rsync to maintain a mirror of RFCs and Internet Drafts can be found here.

10 September 2003 -- Restoration of Corrupted Files
Several years ago, some corruption of unknown source occurred in several of the rfcxxxx.ps files in the RFC Editor directory. We have no way to recreate such Postscript files, and in most cases the original authors are unable to recreate them either. Today we restored rfc1195.ps and rfc1279.ps, using copies maintained by others on the Internet. We appreciate the help of Lawrence D'Oliveiro.

9 September 2003 -- rfc-index.html Available
The RFC Editor web site now contains an XML version of the complete RFC index file. This file, rfc-index.xml, is updated daily to match the venerable textual index file, rfc-index.txt. The corresponding XML schema is rfc-index.xsd. All three files are available on the RFC Database page of the RFC Editor web site.

8 January 2003 -- TAR/ZIP Files in PDF Format
We have extended the repository of tar/zip files containing the complete set of RFCs, recent changes, and subsets of 500 to include copies in PDF format — enabling proper page breaks when printed from Microsoft Windows applications. More information is available on the download web page.

25 June 2002 -- RSYNC Server in Operation
The RFC Editor is now running an rsync server to enable more efficient mirroring of the repository. More information is available at http://www.rfc-editor.org/download.html.

21 May 2002 -- Switch to Mailman
We have moved our RFC-distribution list onto mailman. You can now subscribe and unsubscribe yourself from this list at:
      http://mailman.rfc-editor.org/mailman/listinfo/rfc-dist

28 March 2002 -- .txt.pdf Files for RFCs
The primary version of every RFC is encoded as an ASCII text file, which was once the Lingua Franca of the computer world. However, users of Microsoft Windows often have difficulty displaying vanilla ASCII text files with the correct pagination. To meet this need, the RFC Editor will henceforth provide a PDF format version of every RFC.

Corresponding to every ASCII file ftp://ftp.rfc-editor.org/in-notes/rfcxxxx.txt, there is a PDF file:

      ftp://ftp.rfc-editor.org/in-notes/pdfrfc/rfcxxxx.txt.pdf.

The RFC search engine at www.rfc-editor.org/rfcsearch.html now has buttons labeled:

             RFC File: [X] ASCII+  [ ] PDF.
Choosing "PDF" will return the PDF version when the Number hyperlink is activated.

14 March 2002 -- Updated RFC Editor Web Pages
The RFC Editor web pages have been reformatted for greater convenience.

19 February 2002
RFC readers should be aware that there are many Web sites that mirror RFCs and various forms of RFC indexes, but that these sites vary a great deal in reliability. Some contain factually incorrect information, and some are simply out of date. For the latest and most correct RFC information, go to the RFC Editor web site.

25 January 2002
RFC Editor Report from IETF-52, Salt Lake City, is now available online. Postscript or PDF.

8 January 2002
With the agreement of the IESG, the RFC Editor is instituting a new policy against overly long lists of authors on RFCs. See "Author Overload" in "Recent and Proposed Editorial Policy Changes."

30 October 2001
We have added a new field to the rfc index database: "pub-status", the Status with which the RFC was originally published. Normally Status and Pub-Status will be the same, but they will differ in certain cases -- e.g., Standards moved to Historic, or standards-track documents upgraded without republication. When they do differ, both will be shown in the results of the RFC search engine. E.g., try searching on "1745" (i.e., for RFC 1745).

8 October 2001
The RFC search engine now distinguishes current RFCs from obsoleted RFCs. The title field of the index entry for permanent RFCs is now shown in bold face.

28 August 2001
The repository of private enterprise MIBs from 1990-1998, which used to be available from ftp://ftp.rfc-editor.org/mib/, is now accessible from the Private MIBs directory.

In addition, the standardized MIBs defined in RFC1229-1233 are now in the directory.

14 August 2001
For almost 10 years ISI has provided Web access and search capability for RFCs, Internet Drafts, IAB minutes, and historical Internet-related documents at http://info.internet.isi.edu. This service used a very early Web server which is very obsolete, and ISI has decommissioned that URL.

27 July 2001
Thanks to Mark Handley (ACIRI), we have been able to fix a corrupted line in file rfc1279.ps. As a result, readable Postscript and PDF versions are now available for RFC 1129 (Callon, "Use of OSI IS-IS for Routing in TCP/IP and Dual Environments"). Similar surgery on RFC 1291 (Aggarwal, "Mid-Level Networks: Potential Network Services") was less successful.

13 May 2001
The RFC index incorrectly listed RFC 1129 as status "UNKNOWN". This has been corrected to "INFORMATIONAL".

2 May 2001
We have restored the graph of the number of RFCs published per year.

29 December 2000
A Web page has been added for the RFC-Online Project.

14 December 2000
The RFC search engine has been considerably improved. For example, it now understands that STDs, FYIs, and BCPs are subseries of the RFC series.

20 November 2000
There is now an errata Web page containing RFC errors that have been reported to us.

9 August 2000
The tar/zip files containing the complete set of RFCs, recent changes, and subsets of 500, are all available from a Web page. Note that there are tar/zip files containing RFCs 3001 through the latest published; these are updated weekly.

11 July 2000
Following generally favorable comments, the RFC Editor has set a policy of making all subsidiary versions of RFCs in Postscript (.ps) available in PDF format as well. Today we used distill to create rfcxxx.pdf versions of most of the (non-corrupt) rfcxxx.ps files. The `Format:' clauses of the rfc-index.txt file specifies the size of .pdf files when they are available. A few failed to translate; on the other hand, in some cases the .ps version is corrupt but the .pdf version is OK.

5 April 2000
In response to several requests, we have moved the tar/zip files of all RFCs to the FTPable directory ftp://ftp.rfc-editor.org/in-notes/tar.

16 Mar 2000
In response to several queries: It has been suggested that Postsript (.ps) versions of RFCs should also be available in .pdf format. This seems reasonable, but we have not yet made it a policy. Comments for/against to rfc-editor@rfc-editor.org would be welcome.

Meanwhile, we have a particular problem with RFC1142, a very large and complex RFC (OSI IS-IS definition). We found that both the .ps and the .txt files were mangled. Dave Oran supplied us with the original base document, which is in .pdf. We have used it to renew rfc1142.ps and are working on converting it to a new rfc1142.txt (stay tuned). In any case, it seemed desirable to make the original .pdf file available in the RFC editor archive, so rfc1142.pdf has appeared.

28 Feb 2000
The RFC Editor has tentatively adopted a guideline on the mandatory inclusion of a Table of Contents in new RFCs: an RFC of 50 or more pages will generally be REQUIRED to contain a TOC. This limit was set high as a first cut, and experience may cause it to be lowered.

In general, we want to encourage the inclusion of a TOC in all except the shortest RFCs. A TOC of the appropriate density can be a significant aid to readers. Note that automatic TOC generation by your text preparation tool may produce a TOC that is too dense (and long) to be really useful. If many successive TOC entries point to the same page, your TOC probably needs to be "thinned".

The TOC must be positioned after the Abstract and before the Introduction section (i.e., after the boiler plate and before the body) of your RFC.

26 Feb 2000
There is a new Internet Archaeology Web page, collecting references to early Internet-related documents that the RFC Editor has collected over the years.

24 Feb 2000
The entire RFC series, updated weekly, is now available as a Zip file for Windows systems as well as a tar.gz file for Unix systems.
