2016 June 26th - First Open Source Release

Woohoo, our first open source release! Tons of changes in here to clean it up before public contributors get started.

These changes affect all of the stored procs:

• Only support the SQL Server versions that MS supports - sorry, SQL 2005.
• BREAKING CHANGE: Standardized the input & output parameters to PascalCase. #284
• BREAKING CHANGE: In output tables, the CheckDate field datatype is now DATETIMEOFFSET. This makes it easier to combine results from multiple servers into one table. This is also one of the big reasons we no longer support SQL 2005, which didn't offer this datatype. (Expect to see a lot more cool stuff coming out of this.) #288
• Switched to MIT licensing.
• Switching to semantic versioning. (All of the below are dot-oh releases.)

sp_BlitzFirst v24 (The Artist Formerly Known as sp_AskBrent):

• Renamed from sp_AskBrent because it doesn't feel right to have that branding on an open source proc. I don't want to claim credit for everything as folks add more improvements.
• Only show what queries are running now if @expertmode = 1. #266
• Added several ignorable waits. #268 #174

sp_Blitz v53 recent changes:

• SQL 2016 compatibility - ignores a few changes in 2016's defaults.
• Automatically set @CheckUserDatabaseObjects = 0 if databases have an old compat level that would break in-database checks.
• Check for snapshot backups freezing IO. #178
• Reprioritized a bunch of checks so you can use @IgnorePrioritiesAbove = 50 to get a daily snapshot of really urgent stuff.

sp_BlitzCache v3.0 recent changes:

• Summary output now moved to the second result set instead of the first - makes presentations & explanations easier
• New output fields in @expertmode for more-info, so you can run the stored proc to get additional info about these queries
• Fixed @IgnoreQueryHashes, which probably never worked, hahaha
• Bug fixes - #303, #305
• Erik Darling also added a ton of checks in v2.5.2-3 around expensive sorts, key lookups, remote queries, forced serialization

sp_BlitzIndex v4.0 recent changes:

• Performance improvements
• V3 also added a whole bunch of stuff like prioritized results, new summaries rather than alerting you about tiny indexes, so expect to see a lot less data when you use v3 & v4
