+# Experimental: This is a new format for release notes. The format and availability is subject to change.
+
+## 2021.2.4
+
+### Bug Fixes
+- [configuration] fixes a case where `cloudflared` failed to read URLs in configuration files
+- [logging] cloudflared now logs reason for failed connections if the error is recoverable
+
+## 2021.2.3
+ 
+### Backward Incompatible Changes
+- [db-connect] Removes db-connect from `cloudflared`. The Cloudflare Workers product will continue to support db-connect implementations with versions of `cloudflared` that predate this release and include support for db-connect.
+ 
+### New Features
+- [TCP connects] Introduces support for proxy configurations with websockets in arbitrary TCP connections (#318)
+ 
+### Improvements
+- [command line interface] Nested commands (such as cloudflared tunnel run) now consider CLI arguments even if they appear earlier in the command. E.g. `cloudflared --config config.yaml tunnel run` will now behave similarly to `cloudflared tunnel --config config.yaml run`
+ 
+### Bug Fixes
+- [dns-proxy] The maximum number of upstream connections is now limited by default which should fix reported issues of cloudflared exhausting CPU usage when faced with connectivity issues.

-# Sql driver mock for Golang
-
-**sqlmock** is a mock library implementing [sql/driver](https://godoc.org/database/sql/driver). Which has one and only
-purpose - to simulate any **sql** driver behavior in tests, without needing a real database connection. It helps to
-maintain correct **TDD** workflow.
-
-- this library is now complete and stable. (you may not find new changes for this reason)
-- supports concurrency and multiple connections.
-- supports **go1.8** Context related feature mocking and Named sql parameters.
-- does not require any modifications to your source code.
-- the driver allows to mock any sql driver method behavior.
-- has strict by default expectation order matching.
-- has no third party dependencies.
-
-**NOTE:** in **v1.2.0** **sqlmock.Rows** has changed to struct from interface, if you were using any type references to that
-interface, you will need to switch it to a pointer struct type. Also, **sqlmock.Rows** were used to implement **driver.Rows**
-interface, which was not required or useful for mocking and was removed. Hope it will not cause issues.
-
-## Install
-
-    go get github.com/DATA-DOG/go-sqlmock
-
-## Documentation and Examples
-
-Visit [godoc](http://godoc.org/github.com/DATA-DOG/go-sqlmock) for general examples and public api reference.
-See **.travis.yml** for supported **go** versions.
-Different use case, is to functionally test with a real database - [go-txdb](https://github.com/DATA-DOG/go-txdb)
-all database related actions are isolated within a single transaction so the database can remain in the same state.
-
-See implementation examples:
-
-- [blog API server](https://github.com/DATA-DOG/go-sqlmock/tree/master/examples/blog)
-- [the same orders example](https://github.com/DATA-DOG/go-sqlmock/tree/master/examples/orders)

-## Customize SQL query matching
-
-There were plenty of requests from users regarding SQL query string validation or different matching option.
-We have now implemented the `QueryMatcher` interface, which can be passed through an option when calling
-`sqlmock.New` or `sqlmock.NewWithDSN`.
-
-This now allows to include some library, which would allow for example to parse and validate `mysql` SQL AST.
-And create a custom QueryMatcher in order to validate SQL in sophisticated ways.
-
-By default, **sqlmock** is preserving backward compatibility and default query matcher is `sqlmock.QueryMatcherRegexp`
-which uses expected SQL string as a regular expression to match incoming query string. There is an equality matcher:
-`QueryMatcherEqual` which will do a full case sensitive match.
-
-In order to customize the QueryMatcher, use the following:
-
-``` go
-	db, mock, err := sqlmock.New(sqlmock.QueryMatcherOption(sqlmock.QueryMatcherEqual))
-```
-
-The query matcher can be fully customized based on user needs. **sqlmock** will not
-provide a standard sql parsing matchers, since various drivers may not follow the same SQL standard.
-
-## Matching arguments like time.Time
-
-There may be arguments which are of `struct` type and cannot be compared easily by value like `time.Time`. In this case
-**sqlmock** provides an [Argument](https://godoc.org/github.com/DATA-DOG/go-sqlmock#Argument) interface which
-can be used in more sophisticated matching. Here is a simple example of time argument matching:
-
-``` go
-type AnyTime struct{}
-
-// Match satisfies sqlmock.Argument interface
-func (a AnyTime) Match(v driver.Value) bool {
-	_, ok := v.(time.Time)
-	return ok
-}
-
-func TestAnyTimeArgument(t *testing.T) {
-	t.Parallel()
-	db, mock, err := New()
-	if err != nil {
-		t.Errorf("an error '%s' was not expected when opening a stub database connection", err)
-	}
-	defer db.Close()
-
-	mock.ExpectExec("INSERT INTO users").
-		WithArgs("john", AnyTime{}).
-		WillReturnResult(NewResult(1, 1))
-
-	_, err = db.Exec("INSERT INTO users(name, created_at) VALUES (?, ?)", "john", time.Now())
-	if err != nil {
-		t.Errorf("error '%s' was not expected, while inserting a row", err)
-	}
-
-	if err := mock.ExpectationsWereMet(); err != nil {
-		t.Errorf("there were unfulfilled expectations: %s", err)
-	}
-}
-```
-
-It only asserts that argument is of `time.Time` type.

-## Change Log
-
-- **2019-02-13** - added `go.mod` removed the references and suggestions using `gopkg.in`.
-- **2018-12-11** - added expectation of Rows to be closed, while mocking expected query.
-- **2018-12-11** - introduced an option to provide **QueryMatcher** in order to customize SQL query matching.
-- **2017-09-01** - it is now possible to expect that prepared statement will be closed,
-  using **ExpectedPrepare.WillBeClosed**.
-- **2017-02-09** - implemented support for **go1.8** features. **Rows** interface was changed to struct
-  but contains all methods as before and should maintain backwards compatibility. **ExpectedQuery.WillReturnRows** may now
-  accept multiple row sets.
-- **2016-11-02** - `db.Prepare()` was not validating expected prepare SQL
-  query. It should still be validated even if Exec or Query is not
-  executed on that prepared statement.
-- **2016-02-23** - added **sqlmock.AnyArg()** function to provide any kind
-  of argument matcher.
-- **2016-02-23** - convert expected arguments to driver.Value as natural
-  driver does, the change may affect time.Time comparison and will be
-  stricter. See [issue](https://github.com/DATA-DOG/go-sqlmock/issues/31).
-- **2015-08-27** - **v1** api change, concurrency support, all known issues fixed.
-- **2014-08-16** instead of **panic** during reflect type mismatch when comparing query arguments - now return error
-- **2014-08-14** added **sqlmock.NewErrorResult** which gives an option to return driver.Result with errors for
-interface methods, see [issue](https://github.com/DATA-DOG/go-sqlmock/issues/5)
-- **2014-05-29** allow to match arguments in more sophisticated ways, by providing an **sqlmock.Argument** interface
-- **2014-04-21** introduce **sqlmock.New()** to open a mock database connection for tests. This method
-calls sql.DB.Ping to ensure that connection is open, see [issue](https://github.com/DATA-DOG/go-sqlmock/issues/4).
-This way on Close it will surely assert if all expectations are met, even if database was not triggered at all.
-The old way is still available, but it is advisable to call db.Ping manually before asserting with db.Close.
-- **2014-02-14** RowsFromCSVString is now a part of Rows interface named as FromCSVString.
-It has changed to allow more ways to construct rows and to easily extend this API in future.
-See [issue 1](https://github.com/DATA-DOG/go-sqlmock/issues/1)
-**RowsFromCSVString** is deprecated and will be removed in future
-

-CANTO I
-
-
-IN the midway of this our mortal life,
-I found me in a gloomy wood, astray
-Gone from the path direct: and e'en to tell
-It were no easy task, how savage wild
-That forest, how robust and rough its growth,
-Which to remember only, my dismay
-Renews, in bitterness not far from death.
-Yet to discourse of what there good befell,
-All else will I relate discover'd there.
-How first I enter'd it I scarce can say,
-Such sleepy dullness in that instant weigh'd
-My senses down, when the true path I left,
-But when a mountain's foot I reach'd, where clos'd
-The valley, that had pierc'd my heart with dread,
-I look'd aloft, and saw his shoulders broad
-Already vested with that planet's beam,
-Who leads all wanderers safe through every way.
-
-Then was a little respite to the fear,
-That in my heart's recesses deep had lain,
-All of that night, so pitifully pass'd:
-And as a man, with difficult short breath,
-Forespent with toiling, 'scap'd from sea to shore,
-Turns to the perilous wide waste, and stands
-At gaze; e'en so my spirit, that yet fail'd
-Struggling with terror, turn'd to view the straits,
-That none hath pass'd and liv'd.  My weary frame
-After short pause recomforted, again
-I journey'd on over that lonely steep,
-
-The hinder foot still firmer.  Scarce the ascent
-Began, when, lo! a panther, nimble, light,
-And cover'd with a speckled skin, appear'd,
-Nor, when it saw me, vanish'd, rather strove
-To check my onward going; that ofttimes
-With purpose to retrace my steps I turn'd.
-
-The hour was morning's prime, and on his way
-Aloft the sun ascended with those stars,
-That with him rose, when Love divine first mov'd
-Those its fair works: so that with joyous hope
-All things conspir'd to fill me, the gay skin
-Of that swift animal, the matin dawn
-And the sweet season.  Soon that joy was chas'd,
-And by new dread succeeded, when in view
-A lion came, 'gainst me, as it appear'd,
-
-With his head held aloft and hunger-mad,
-That e'en the air was fear-struck.  A she-wolf
-Was at his heels, who in her leanness seem'd
-Full of all wants, and many a land hath made
-Disconsolate ere now.  She with such fear
-O'erwhelmed me, at the sight of her appall'd,
-That of the height all hope I lost.  As one,
-Who with his gain elated, sees the time
-When all unwares is gone, he inwardly
-Mourns with heart-griping anguish; such was I,
-Haunted by that fell beast, never at peace,
-Who coming o'er against me, by degrees
-Impell'd me where the sun in silence rests.
-
-While to the lower space with backward step
-I fell, my ken discern'd the form one of one,
-Whose voice seem'd faint through long disuse of speech.
-When him in that great desert I espied,
-"Have mercy on me!" cried I out aloud,
-"Spirit! or living man! what e'er thou be!"
-
-He answer'd: "Now not man, man once I was,
-And born of Lombard parents, Mantuana both
-By country, when the power of Julius yet
-Was scarcely firm.  At Rome my life was past
-Beneath the mild Augustus, in the time
-Of fabled deities and false.  A bard
-Was I, and made Anchises' upright son
-The subject of my song, who came from Troy,
-When the flames prey'd on Ilium's haughty towers.
-But thou, say wherefore to such perils past
-Return'st thou?  wherefore not this pleasant mount
-Ascendest, cause and source of all delight?"
-"And art thou then that Virgil, that well-spring,
-From which such copious floods of eloquence
-Have issued?"  I with front abash'd replied.
-"Glory and light of all the tuneful train!
-May it avail me that I long with zeal
-Have sought thy volume, and with love immense
-Have conn'd it o'er.  My master thou and guide!
-Thou he from whom alone I have deriv'd
-That style, which for its beauty into fame
-Exalts me.  See the beast, from whom I fled.
-O save me from her, thou illustrious sage!"
-
-"For every vein and pulse throughout my frame
-She hath made tremble."  He, soon as he saw
-That I was weeping, answer'd, "Thou must needs
-Another way pursue, if thou wouldst 'scape
-From out that savage wilderness.  This beast,
-At whom thou criest, her way will suffer none
-To pass, and no less hindrance makes than death:
-So bad and so accursed in her kind,
-That never sated is her ravenous will,
-Still after food more craving than before.
-To many an animal in wedlock vile
-She fastens, and shall yet to many more,
-Until that greyhound come, who shall destroy
-Her with sharp pain.  He will not life support
-By earth nor its base metals, but by love,
-Wisdom, and virtue, and his land shall be
-The land 'twixt either Feltro.  In his might
-Shall safety to Italia's plains arise,
-For whose fair realm, Camilla, virgin pure,
-Nisus, Euryalus, and Turnus fell.
-He with incessant chase through every town
-Shall worry, until he to hell at length
-Restore her, thence by envy first let loose.
-I for thy profit pond'ring now devise,
-That thou mayst follow me, and I thy guide
-Will lead thee hence through an eternal space,
-Where thou shalt hear despairing shrieks, and see
-Spirits of old tormented, who invoke
-A second death; and those next view, who dwell
-Content in fire, for that they hope to come,
-Whene'er the time may be, among the blest,
-Into whose regions if thou then desire
-T' ascend, a spirit worthier then I
-Must lead thee, in whose charge, when I depart,
-Thou shalt be left: for that Almighty King,
-Who reigns above, a rebel to his law,
-Adjudges me, and therefore hath decreed,
-That to his city none through me should come.
-He in all parts hath sway; there rules, there holds
-His citadel and throne.  O happy those,
-Whom there he chooses!"  I to him in few:
-"Bard! by that God, whom thou didst not adore,
-I do beseech thee (that this ill and worse
-I may escape) to lead me, where thou saidst,
-That I Saint Peter's gate may view, and those
-Who as thou tell'st, are in such dismal plight."
-
-Onward he mov'd, I close his steps pursu'd.

-
-## Install
-
-Requires Go 1.8 or above.
-
-Install with `go get github.com/denisenkom/go-mssqldb` .
-
-## Connection Parameters and DSN
-
-The recommended connection string uses a URL format:
-`sqlserver://username:password@host/instance?param1=value&param2=value`
-Other supported formats are listed below.
-
-### Common parameters:
-
-* `user id` - enter the SQL Server Authentication user id or the Windows Authentication user id in the DOMAIN\User format. On Windows, if user id is empty or missing Single-Sign-On is used.
-* `password`
-* `database`
-* `connection timeout` - in seconds (default is 0 for no timeout), set to 0 for no timeout. Recommended to set to 0 and use context to manage query and connection timeouts.
-* `dial timeout` - in seconds (default is 15), set to 0 for no timeout
-* `encrypt`
-  * `disable` - Data send between client and server is not encrypted.
-  * `false` - Data sent between client and server is not encrypted beyond the login packet. (Default)
-  * `true` - Data sent between client and server is encrypted.
-* `app name` - The application name (default is go-mssqldb)
-
-### Connection parameters for ODBC and ADO style connection strings:
-
-* `server` - host or host\instance (default localhost)
-* `port` - used only when there is no instance in server (default 1433)
-
-### Less common parameters:
-
-* `keepAlive` - in seconds; 0 to disable (default is 30)
-* `failoverpartner` - host or host\instance (default is no partner). 
-* `failoverport` - used only when there is no instance in failoverpartner (default 1433)
-* `packet size` - in bytes; 512 to 32767 (default is 4096)
-  * Encrypted connections have a maximum packet size of 16383 bytes
-  * Further information on usage: https://docs.microsoft.com/en-us/sql/database-engine/configure-windows/configure-the-network-packet-size-server-configuration-option
-* `log` - logging flags (default 0/no logging, 63 for full logging)
-  *  1 log errors
-  *  2 log messages
-  *  4 log rows affected
-  *  8 trace sql statements
-  * 16 log statement parameters
-  * 32 log transaction begin/end
-* `TrustServerCertificate`
-  * false - Server certificate is checked. Default is false if encypt is specified.
-  * true - Server certificate is not checked. Default is true if encrypt is not specified. If trust server certificate is true, driver accepts any certificate presented by the server and any host name in that certificate. In this mode, TLS is susceptible to man-in-the-middle attacks. This should be used only for testing.
-* `certificate` - The file that contains the public key certificate of the CA that signed the SQL Server certificate. The specified certificate overrides the go platform specific CA certificates.
-* `hostNameInCertificate` - Specifies the Common Name (CN) in the server certificate. Default value is the server host.
-* `ServerSPN` - The kerberos SPN (Service Principal Name) for the server. Default is MSSQLSvc/host:port.
-* `Workstation ID` - The workstation name (default is the host name)
-* `ApplicationIntent` - Can be given the value `ReadOnly` to initiate a read-only connection to an Availability Group listener. The `database` must be specified when connecting with `Application Intent` set to `ReadOnly`. 
-
-### The connection string can be specified in one of three formats:
-
-
-1. URL: with `sqlserver` scheme. username and password appears before the host. Any instance appears as
-    the first segment in the path. All other options are query parameters. Examples:
-
-  * `sqlserver://username:password@host/instance?param1=value&param2=value`
-  * `sqlserver://username:password@host:port?param1=value&param2=value`
-  * `sqlserver://sa@localhost/SQLExpress?database=master&connection+timeout=30` // `SQLExpress instance.
-  * `sqlserver://sa:mypass@localhost?database=master&connection+timeout=30`     // username=sa, password=mypass.
-  * `sqlserver://sa:mypass@localhost:1234?database=master&connection+timeout=30` // port 1234 on localhost.
-  * `sqlserver://sa:my%7Bpass@somehost?connection+timeout=30` // password is "my{pass"
-
-  A string of this format can be constructed using the `URL` type in the `net/url` package.
-
-```go
-  query := url.Values{}
-  query.Add("app name", "MyAppName")
-
-  u := &url.URL{
-      Scheme:   "sqlserver",
-      User:     url.UserPassword(username, password),
-      Host:     fmt.Sprintf("%s:%d", hostname, port),
-      // Path:  instance, // if connecting to an instance instead of a port
-      RawQuery: query.Encode(),
-  }
-  db, err := sql.Open("sqlserver", u.String())
-```
-
-2. ADO: `key=value` pairs separated by `;`. Values may not contain `;`, leading and trailing whitespace is ignored.
-     Examples:
-	
-  * `server=localhost\\SQLExpress;user id=sa;database=master;app name=MyAppName`
-  * `server=localhost;user id=sa;database=master;app name=MyAppName`
-
-3. ODBC: Prefix with `odbc`, `key=value` pairs separated by `;`. Allow `;` by wrapping
-    values in `{}`. Examples:
-	
-  * `odbc:server=localhost\\SQLExpress;user id=sa;database=master;app name=MyAppName`
-  * `odbc:server=localhost;user id=sa;database=master;app name=MyAppName`
-  * `odbc:server=localhost;user id=sa;password={foo;bar}` // Value marked with `{}`, password is "foo;bar"
-  * `odbc:server=localhost;user id=sa;password={foo{bar}` // Value marked with `{}`, password is "foo{bar"
-  * `odbc:server=localhost;user id=sa;password={foobar }` // Value marked with `{}`, password is "foobar "
-  * `odbc:server=localhost;user id=sa;password=foo{bar`   // Literal `{`, password is "foo{bar"
-  * `odbc:server=localhost;user id=sa;password=foo}bar`   // Literal `}`, password is "foo}bar"
-  * `odbc:server=localhost;user id=sa;password={foo{bar}` // Literal `{`, password is "foo{bar"
-  * `odbc:server=localhost;user id=sa;password={foo}}bar}` // Escaped `} with `}}`, password is "foo}bar"
-
-## Executing Stored Procedures
-
-To run a stored procedure, set the query text to the procedure name:
-```go
-var account = "abc"
-_, err := db.ExecContext(ctx, "sp_RunMe",
-	sql.Named("ID", 123),
-	sql.Named("Account", sql.Out{Dest: &account}),
-)
-```
-
-## Reading Output Parameters from a Stored Procedure with Resultset
-
-To read output parameters from a stored procedure with resultset, make sure you read all the rows before reading the output parameters:
-```go
-sqltextcreate := `
-CREATE PROCEDURE spwithoutputandrows
-	@bitparam BIT OUTPUT
-AS BEGIN
-	SET @bitparam = 1
-	SELECT 'Row 1'
-END
-`
-var bitout int64
-rows, err := db.QueryContext(ctx, "spwithoutputandrows", sql.Named("bitparam", sql.Out{Dest: &bitout}))
-var strrow string
-for rows.Next() {
-	err = rows.Scan(&strrow)
-}
-fmt.Printf("bitparam is %d", bitout)
-```
-
-## Caveat for local temporary tables
-
-Due to protocol limitations, temporary tables will only be allocated on the connection
-as a result of executing a query with zero parameters. The following query
-will, due to the use of a parameter, execute in its own session,
-and `#mytemp` will be de-allocated right away:
-
-```go
-conn, err := pool.Conn(ctx)
-defer conn.Close()
-_, err := conn.ExecContext(ctx, "select @p1 as x into #mytemp", 1)
-// at this point #mytemp is already dropped again as the session of the ExecContext is over
-```
-
-To work around this, always explicitly create the local temporary
-table in a query without any parameters. As a special case, the driver
-will then be able to execute the query directly on the
-connection-scoped session. The following example works:
-
-```go
-conn, err := pool.Conn(ctx)
-
-// Set us up so that temp table is always cleaned up, since conn.Close()
-// merely returns conn to pool, rather than actually closing the connection.
-defer func() {
-	_, _ = conn.ExecContext(ctx, "drop table #mytemp")  // always clean up
-	conn.Close() // merely returns conn to pool
-}()
-
-
-// Since we not pass any parameters below, the query will execute on the scope of
-// the connection and succeed in creating the table.
-_, err := conn.ExecContext(ctx, "create table #mytemp ( x int )")
-
-// #mytemp is now available even if you pass parameters
-_, err := conn.ExecContext(ctx, "insert into #mytemp (x) values (@p1)", 1)
-
-```
-
-## Return Status
-
-To get the procedure return status, pass into the parameters a
-`*mssql.ReturnStatus`. For example:
-```
-var rs mssql.ReturnStatus
-_, err := db.ExecContext(ctx, "theproc", &rs)
-log.Printf("status=%d", rs)
-```
-
-or
-
-```
-var rs mssql.ReturnStatus
-_, err := db.QueryContext(ctx, "theproc", &rs)
-for rows.Next() {
-	err = rows.Scan(&val)
-}
-log.Printf("status=%d", rs)
-```
-
-Limitation: ReturnStatus cannot be retrieved using `QueryRow`.
-
-## Parameters
-
-The `sqlserver` driver uses normal MS SQL Server syntax and expects parameters in
-the sql query to be in the form of either `@Name` or `@p1` to `@pN` (ordinal position).
-
-```go
-db.QueryContext(ctx, `select * from t where ID = @ID and Name = @p2;`, sql.Named("ID", 6), "Bob")
-```
-
-### Parameter Types
-
-To pass specific types to the query parameters, say `varchar` or `date` types,
-you must convert the types to the type before passing in. The following types
-are supported:
-
- * string -> nvarchar
- * mssql.VarChar -> varchar
- * time.Time -> datetimeoffset or datetime (TDS version dependent)
- * mssql.DateTime1 -> datetime
- * mssql.DateTimeOffset -> datetimeoffset
- * "github.com/golang-sql/civil".Date -> date
- * "github.com/golang-sql/civil".DateTime -> datetime2
- * "github.com/golang-sql/civil".Time -> time
- * mssql.TVP -> Table Value Parameter (TDS version dependent)
-
-## Important Notes
-
- * [LastInsertId](https://golang.org/pkg/database/sql/#Result.LastInsertId) should
-    not be used with this driver (or SQL Server) due to how the TDS protocol
-	works. Please use the [OUTPUT Clause](https://docs.microsoft.com/en-us/sql/t-sql/queries/output-clause-transact-sql)
-	or add a `select ID = convert(bigint, SCOPE_IDENTITY());` to the end of your
-	query (ref [SCOPE_IDENTITY](https://docs.microsoft.com/en-us/sql/t-sql/functions/scope-identity-transact-sql)).
-	This will ensure you are getting the correct ID and will prevent a network round trip.
- * [NewConnector](https://godoc.org/github.com/denisenkom/go-mssqldb#NewConnector)
-    may be used with [OpenDB](https://golang.org/pkg/database/sql/#OpenDB).
- * [Connector.SessionInitSQL](https://godoc.org/github.com/denisenkom/go-mssqldb#Connector.SessionInitSQL)
-	may be set to set any driver specific session settings after the session
-	has been reset. If empty the session will still be reset but use the database
-	defaults in Go1.10+.
-
-## Features
-
-* Can be used with SQL Server 2005 or newer
-* Can be used with Microsoft Azure SQL Database
-* Can be used on all go supported platforms (e.g. Linux, Mac OS X and Windows)
-* Supports new date/time types: date, time, datetime2, datetimeoffset
-* Supports string parameters longer than 8000 characters
-* Supports encryption using SSL/TLS
-* Supports SQL Server and Windows Authentication
-* Supports Single-Sign-On on Windows
-* Supports connections to AlwaysOn Availability Group listeners, including re-direction to read-only replicas.
-* Supports query notifications
-
-## Tests
-
-`go test` is used for testing. A running instance of MSSQL server is required.
-Environment variables are used to pass login information.
-
-Example:
-
-    env SQLSERVER_DSN=sqlserver://user:pass@hostname/instance?database=test1 go test
-
-## Deprecated
-
-These features still exist in the driver, but they are are deprecated.
-
-### Query Parameter Token Replace (driver "mssql")
-
-If you use the driver name "mssql" (rather then "sqlserver") the SQL text
-will be loosly parsed and an attempt to extract identifiers using one of
-
-* ?
-* ?nnn
-* :nnn
-* $nnn
-
-will be used. This is not recommended with SQL Server. 
-There is at least one existing `won't fix` issue with the query parsing.
-
-Use the native "@Name" parameters instead with the "sqlserver" driver name.
-
-## Known Issues
-
-* SQL Server 2008 and 2008 R2 engine cannot handle login records when SSL encryption is not disabled.
-To fix SQL Server 2008 R2 issue, install SQL Server 2008 R2 Service Pack 2.
-To fix SQL Server 2008 issue, install Microsoft SQL Server 2008 Service Pack 3 and Cumulative update package 3 for SQL Server 2008 SP3.
