This release brings with it the recovery tool needed for people that have missed out on the previous transition phase, or users that were vulnerable due to continuous key re-use, to reclaim their tokens. This is a two stage claim phase, whereby in the first phase you submit the proof to the Tangle, and in the second one the address to which the tokens will be automatically sent to. This release is currently being scheduled for next week.

Please make sure to keep your old and new seeds! Here is a blog post about this release: https://blog.iota.org/gui-v2-5-2-latest-release-with-iota-reclaim-tool-32d364d6241a
