-## What's New in TLSH 4.10.x
-22/09/2021
-
-Release version 4.8.x	- merged in pull requests for more stable installation.
-
-Release version 4.9.x	- added -thread and -private options.
-- Both versions are faster than previous versions, but they set the checksum to 00.
-- This loses a very small part of the functionality.
-- See 4.9.3 in the Change_History to see timing comparisons.

 Release version 4.10.x	- a Python clustering tool.

-TLSH has gained some traction. It has been included in STIX 2.1 and been ported to a number of langauges.
-
-We have added a version identifier ("T1") to the start of the digest so that we can
-cleary distinguish between different variants of the digest (such as non-standard choices of 3 byte checksum).
-This means that we do not rely on the length of the hex string to determine if a hex string is a TLSH digest
-(this is a brittle method for identifying TLSH digests).
-We are doing this to enable compatibility, especially backwards compatibility of the TLSH approach.
-
+We have added a version identifier ("T1") to the start of the digest.
+Please use versions of TLSH that have the T1 header
 The code is backwards compatible, it can still read and interpret 70 hex character strings as TLSH digests.
 And data sets can include mixes of the old and new digests.
 If you need old style TLSH digests to be outputted, then use the command line option '-old'
