Which version of Jsp is the lastest? -


i downloaded jsp-api https://repo.maven.apache.org/, found versions weird.

maven dependecies:

<dependency>     <groupid>javax.servlet.jsp</groupid>     <artifactid>jsp-api</artifactid>     <version>2.1</version> </dependency>  <dependency>     <groupid>javax.servlet.jsp</groupid>     <artifactid>jsp-api</artifactid>     <version>2.2</version> </dependency>

version2.2 has 3 packages:

javax.servlet.jsp javax.servlet.jsp.el javax.servlet.jsp.tagext

version2.1 has 4 packages:

javax.el javax.servlet.jsp javax.servlet.jsp.el javax.servlet.jsp.tagext

some classes deprecated in javax.servlet.jsp package, javax.servlet.jsp.el.elexception replaced javax.el.elexception.

however, in version2.2, there isn't javax.el package. why javax.el package disappear in version2.2?

in addition, searched jsp-api in http://mvnrepository.com , found version2.3.1. after downloading it, found same version2.2 downloaded before.

in end, seems found official websitehttps://jsp.java.net/. doesn't explain version of jsp-api. metions version2.1.

i'm confused these versions. give me explanation version of jsp?

latest version 2.3
here.
technically, jsp 2.3 second maintenance release of jsp 2.1. jsp 2.3 second maintenance release of jsp 2.1
