The page’s infobox gives 1998 as the “Initial release,” but Ericsson’s own Erlang/OTP history says otherwise.

An official Erlang/OTP blog post states: “The first release, OTP R1B, was released in 1996.” That directly contradicts an initial-release date of 1998.

1998 is an important year in Erlang/OTP history for a different reason: Ericsson released Erlang/OTP as open source in December 1998. But that is not the same thing as the software’s initial release. The product had already had OTP releases before then.

This sentence introduces the list below as the applications included in OTP 18.2, but Ericsson’s official OTP 18.2 release page gives a materially different application list.

According to the official OTP 18.2 release page, the packaged applications were:
asn1, common_test, compiler, crypto, dialyzer, diameter, erl_docgen, erl_interface, erts, eunit, hipe, inets, jinterface, kernel, observer, parsetools, public_key, runtime_tools, sasl, snmp, ssh, ssl, stdlib, test_server, tools, typer, wx, and xmerl.

The list shown in the article omits many of those official OTP 18.2 applications — for example kernel, observer, parsetools, public_key, runtime_tools, sasl, snmp, ssh, ssl, stdlib, test_server, tools, typer, wx, and xmerl. It also includes applications such as cosEvent, cosNotification, cosTime, cosTransactions, and ic, which do not appear in Ericsson’s official OTP 18.2 application list.

So the statement is inaccurate as presented: the list under it is not the official set of applications included in OTP 18.2.
