At the beginning of this year I announced the intention of the LTS team to support 4.6 as the next LTS and we are committed to keeping 4.6 secure until one year after we stopped supporting 4.4 - ie. the end of January 2017. As with 4.4 the level of support will tail off as key contributors move off 4.6. At this stage we are still getting a large number of fixes for 4.6 and expect to see monthly point releases continuing for the rest of the year.
