Hello, We are planning to release Mbed TLS 3.0 around June 2021, alongside an LTS release of Mbed TLS 2.x. Our major version numbers indicate API breaking changes, and this is no exception: Mbed TLS 3.0 will have changes that make it incompatible with 2.x (as an obvious example, functions that are deprecated in 2.x will be removed). In setting a near-term release date, we have chosen some key areas that we want to focus on for 3.0. Some other API-breaking items (i.e., those requiring significant design time) won't make the cut and we will hold those back for a future major version, in order to have time to get them right. The main focus for 3.0 will be reduction in API surface, and changes that are low-impact for almost everyone. Work towards 3.0 will start in late January, on the development branch which will contain a public work-in-progress view of Mbed TLS 3.0. Any work for 2.x in this timeframe will take place on a separate branch (provisionally named like "mbedtls-2.x"). During the 3.0 development period, bug fixes and security fixes will continue to be a priority, but we will have slightly less capacity for other features. While 3.0 is in development, any new features will by default be landed in 3.0 only, unless there is a strong case for back-porting to 2.x. The 2.x LTS branches will still be supported with bug fixes and security fixes for the normal three year lifetime (i.e., the final LTS release of 2.x in mid-2021 will be supported until mid-2024). In terms of content, we are taking a cautious approach to what we plan for 3.0. In the past we've been ambitious here and as a result, have slipped on the release date; by being cautious on feature set we can be confident about hitting the mid-year release date. We won't try to make all of the changes that would be nice-to-have; instead, we will focus on tasks that reduce maintenance, unlock other improvements in a 3.x timeframe, are still valuable if only partially completed, and can fit within this time frame. Currently we're looking at the following areas for 3.0: * Reduce the public surface of the API * Clean-up existing APIs * Changes to default options Regards Dave Rodgman
