1.6.0 RC is almost ready. Get a sneak peak of what might be in it here

Here’s a quick rundown of what to look forward to, and of course features may be added or removed prior to the RC or full release:

• Tons of new docs from @bernhard on how to extended and upgrade contracts, functional programming 101, the DAML Standard Library, and testing your contracts. All the docs are in PRs for now but docs.daml.com will have all of these once 1.6.0 is marked stable.
• Added undefined to Prelude so you can declare functions while coding and prototyping without immediately defining them. Thanks @Tamas_Kalcza for adding and @Luciano for reporting. #7058
• That pesky and confusing daml 1.2 header is now deprecated. #7513
• You can now specify DAML Navigator’s port with --navigator-port in daml start #7401
• DA.Date.date now properly raises an error when a date is outside the valid range. Thanks to @Sofia_Faro for fixing and @gyorgybalazsi for reporting! #7393
• You can now queryContractKey in DAML Script which is the ContractKey equivalent of queryContractId #7354
• streamQueries and streamFetchByKeys (in the JavaScript libraries) have had new methods added that can take multiple queries/keys and return a union of them #7066
