New Features

• Add support to NETStandard 2.0 (with support to Shared mode)
• New document Expression parser/executor - see Expression Wiki
• Support index creation with expressions

col.EnsureIndex(x => x.Name, "LOWER($.Name)");
col.EnsureIndex("GrandTotal", "SUM($.Items[*].Qtd * $.Items[*].Price)");

• Query with Include it´s supported in Engine level with ANY nested includes

col.Include(x => x.Users)
   .Include(x => x.Users[0].Address)
   .Include(x => x.Users[0].Address.City)
   .Find(...)

• Support complex Linq queries using LinqQuery compiler (works as linq to object)
  • col.Find(x => x.Name == "John" && x.Items.Length.ToString().EndsWith == "0")
• Better execution plan (with debug info) in multi query statements
• No more external journal file - use same datafile to store temporary data
• Fixed concurrency problems (keeps thread/process safe)
• Convert Query.And to Query.Between when possible
• Add support to Query.Between open/close interval
• Same datafile from LiteDB v3 (no upgrade needed)

Shell

• New UPDATE/SELECT statements in shell
• Shell commands parser/executor are back into LiteDB.dll

  (preparing to new visual LiteDB database management tool)

Break changes

• Remove transactions
• Remove auto-id register function for custom type
• Remove index definitions on mapper (fluent/attribute)
