April 7, 2022: InChI Days 2022 Symposium
Our InChI Days 2022 virtual symposium brought together much of the InChI development community to discuss directions and future evolution of the InChI Standard. While the InChI Standard is quite stable and used across much of the organic chemistry space, our symposium covered a wide and diverse suite of extensions being studied by working groups of experts in each area. Topics covered by these teams at our meeting included extended stereochemistry, extended tautomers, polymers, Markush/variable structures, mixtures, reactions, nanomamaterials, isotopologues and the use of QR codes. We have the slide decks from the sessions available on our website (https://www.inchi-trust.org/wp/decks-open-inchi-days-2022/). If you are interested in InChI or any of these extensions, sign up for our newsletter InChI OUTREACH: SUBSCRIBE to InChI OUTREACH.

November 10, 2021: We sadly note the passing of Igor Pletnev
Igor Pletnev was the developer and caretaker of the InChI software algorithm for over 15 years, first at NIST and then at the InChI Trust. Over the years Igor made great contributions to the InChI project. His knowledge of both chemistry and computer programming made him a unique person to carry out all these tasks while interacting with chemists around the world on an almost daily basis. While there were many demands on his work efforts with the InChI algorithm, Igor always was calm and friendly to all, a true professional at all times. He will be missed and dearly remembered for all of his outstanding work by all of us at InChI Trust and the global community of InChI developers and users.
September 1, 2021: New Team Members Added
The InChI Trust added two new positions to help advance the extension of the InChI code as well as its awareness and use across the community.
Gerd Blanke (firstname.lastname@example.org) is the Technical Director for the Trust. He is working closely with the working groups to help move the various activities to delivery in next versions of the code. Gerd has held senior positions in information technology and services across the research area of life science and chemical industry. His business development skills span chemical and bio informatics, databases, data analytics, business Intelligence, project management, and management. (https://www.linkedin.com/in/gerd-blanke-b13115).
Rudy Potenzone (email@example.com) is the Director of Outreach and Marketing, including extensions to the website, a newsletter (InChI OUTREACH), and a program to reach out to potential new sponsors, developers and users. Rudy is an accomplished executive with a proven track record of developing products for life science informatics, knowledge management, workflow systems and electronic lab notebooks.

December 15, 2020: InChI Code Release 1.06
InChI v1.06 (https://www.inchi-trust.org/wp/downloads/) is now available. This new version includes pseudo-atoms, which have a variety of uses including an improved description of polymers. There are also various bug-fixes and technical changes which will be very useful for programmers but which will probably not be noticed by everyone who uses the code just to generate standard InChI. The initial work for contracts for organometallics, coordination compounds, inorganics, and extended tautomers has been completed and the working groups are now analyzing and discussing the resulting work to determine the next VU steps.
January 27, 2017: InChI 1.05 and Reaction InChI (RInChI) 1.0 Released
Version 1.05 of the InChI software was released, along with version 1.00 of the Reaction InChI (RInChI)
June 1, 2011: InChI 1.04 and the InChI Certification Suite Released
Version 1.04 of the InChI software was released as well as an InChI Certification Suite which is designed to check the correct installation of the InChI software. Certification logos for correct installations as well as InChI Trust member and supporter logos are provided by the InChI Trust.
July 1, 2009: The InChI Trust was formed
The InChI Trust was formed. The 2009 Board of Directors consists of 8 members: The Royal Society of Chemistry • Nature Publishing Group • Elsevier Properties SA • Thomson Reuters • John Wiley & Sons • FIZ CHEMIE • Taylor & Francis • IUPAC
January 6, 2009: Standard versions of InChI and the InChIKey released

June 3, 2008: InChIKey - a shorter hash key version of InChI
A shorter hash key version of InChI, known as InChIKey was developed by Igor Pletnev. This alternative format is much more suitable for use in search engines and offers many new possibilities for software applications.
August 1, 2006: InChI Version 1 Released
version 1 of the IUPAC International Chemical Identifier (InChI) was launched. The development and associated programming work was predominantly carried out by Dmitrii Tchekhovskoi.
June 1, 2001: IUPAC Chemical Identifier Project - InChI - Initiated
The IUPAC Chemical Identifier project began in collaboration with the US National Institute of Standards and Technology (NIST). The aim was to devise a computer based algorithm yielding a unique label for any chemical structure, regardless of how it was represented (on screen).
June 5, 2000: First Organizational Meeting for InChI
From a meeting with a wide range of users of chemical nomenclature including database providers, patent officials, international trade representatives, et al, under the direction of Alan McNaught, it was decided that InChI would be an IUPAC initiative to meet the needs of the chemical and related communities.
June 1, 1998: Initial Proposal for a Public Domain Structure Standard
Steve Heller initiated a proposal at the National Institute of Standards and Technology (NIST) for a public domain structure representation standard for the NIST databases, along with Steve Stein who was the initial designer and architect for the project.
