The most important changes in an overview:

Support of Elliptic Curve Cryptography (ECC)

With the integration of the upcoming GnuPG 2.2 release candidate.

There are a lot more general improvements coming with GnuPG 2.2, for a long technical list, see

Preparing for better overall crypto user experience

Fetching pubkeys by default. Most users want some basic level of confidentiality for their email and file exchanges without having to deal with crypto details like distributing and checking pubkeys and their signatures. An update to Gpg4win 3.0 will provide an implementation of a concept called `web key directory/service`. Version 3.0 already contains some changes preparing for the concept: It will by default try to fetch missing pubkeys and find them for a given email address. This behavior can be switched off, of course. For details see

Major Outlook-Support improvement for attachments and encodings

The included Outlook Plugin (GpgOL) has been completely overhauled.

Kleopatra (Crypto-Manager)
