+Optimus is published to Maven Central for Scala 2.12, 2.13 and 3.1.3! 
 
 Add the following dependencies to your SBT build file in order to get started:
 
 ```scala
 libraryDependencies ++= Seq(
-    "com.github.vagmcs" %% "optimus" % "3.4.2",
-    "com.github.vagmcs" %% "optimus-solver-oj" % "3.4.2",
-    "com.github.vagmcs" %% "optimus-solver-lp" % "3.4.2"

+    "com.github.vagmcs" %% "optimus-solver-oj" % "3.4.3",
+    "com.github.vagmcs" %% "optimus-solver-lp" % "3.4.3"
 )
 ```
 
 Optionally, you can also add the following extra dependencies for proprietary solvers:
 
 ```scala
-"com.github.vagmcs" %% "optimus-solver-gurobi" % "3.4.2"
-"com.github.vagmcs" %% "optimus-solver-mosek" % "3.4.2"
+"com.github.vagmcs" %% "optimus-solver-gurobi" % "3.4.3"
+"com.github.vagmcs" %% "optimus-solver-mosek" % "3.4.3"
 ```

 # Building and Linking Optimus
 
-Optimus is builds for Scala 2.12 and 2.13. In order to build Optimus modules (`core`, `solver-oj`, `solver-lp`, `solver-gurobi`, `solver-mosek`) from source you need to have Java 8 or higher and [SBT](http://www.scala-sbt.org/) installed in your system. Optimus build optionally depends on [Gurobi](http://www.gurobi.com/) and [Mosek](https://www.mosek.com/) solvers. In case the dependencies for Gurobi or Mosek are not included, Optimus would build a minimal version having only lp solve and oj solver.
