Change:
In , NAME points out that the backticks don't render nicely in the TXT version, so let's remove them

Discussion:
During the handshake, endpoints will exchange Version Information, which is a blob of data that is defined below.  In QUIC version 1, the Version Information is transmitted using a new transport <del> parameter, "version_information".  The contents of Version Information are shown below (using the notation from the "Notational Conventions" section of QUIC): </del> <ins> parameter, version_information.  The contents of Version Information are shown below (using the notation from the "Notational Conventions" section of QUIC): </ins> The content of each field is described below:

In most cases, this field will be equal to the value of the Version field in the long header that carries this data. <del> The contents of the "Other Versions" field depends on whether it is </del> <ins> The contents of the Other Versions field depends on whether it is </ins> sent by the client or by the server. <del> When sent by a client, the "Other Versions" field lists all the </del> <ins> When sent by a client, the Other Versions field lists all the </ins> versions that this first flight is compatible with, ordered by <del> descending preference.  Note that the version in the "Chosen Version" field MUST be included in this list to allow the client to communicate the chosen version's preference.  Note that this </del> <ins> descending preference.  Note that the version in the Chosen Version field MUST be included in this list to allow the client to communicate the chosen version's preference.  Note that this </ins> preference is only advisory, servers MAY choose to use their own preference instead. <del> When sent by a server, the "Other Versions" field lists all the </del> <ins> When sent by a server, the Other Versions field lists all the </ins> Fully-Deployed Versions of this server deployment, see server- <del> fleet.  Note that the version in the "Chosen Version" field is not </del> <ins> fleet.  Note that the version in the Chosen Version field is not </ins> necessarily included in this list, because the server operator could be in the process of removing support for this version.  For the same reason, this field MAY be empty. Clients and servers MAY both include versions following the pattern <del> "0x?a?a?a?a" in their "Other Versions" list.  Those versions are reserved to exercise version negotiation (see the Versions section of QUIC), and will never be selected when choosing a version to use. </del> <ins> 0x?a?a?a?a in their Other Versions list.

Downgrade prevention also depends on the client ignoring Version Negotiation packets that contain the original version; see incompat-vn.

That </del> <ins> sent in the Chosen Version field of its Version Information.  That </ins> remains true even if other versions were used in the Version field of long headers at any point in the lifetime of the connection; endpoints MUST NOT change the version that they consider to be in use
