Release 3.3

• New API for tool-info modules (needed by benchexec for getting information about the benchmarked tool). The new API is defined by class benchexec.tools.template.BaseTool2 and is similar to the old API, but more convenient to use and provides more useful information to the tool-info module.
  The old API is still supported and will be removed no sooner than in BenchExec 4.0. We also provide a migration guide.

• A new parameter --tool-directory for benchexec allows to specify the installation directory of the benchmarked tool easily without having to modify PATH or change into the tool's directory.
  Note that this only works if the respective tool-info module makes use of the new BaseTool2 API.

• New version 2.0 of the task-definition format for benchexec.
  This format allows to specify arbitrary additional information in a key named options and benchexec will pass everything in this key to the tool-info module, but note that this only works if the respective tool-info module makes use of the new BaseTool2 API.
  This is useful to add domain-specific information about tasks, for example in the SV-Benchmarks repository it is used to declare the program language.
  BenchExec also still supports version 1.0 of the format.

• table-generator is now defined to work on Windows and we test this in continuous integration.
  Previously, it probably was working on Windows most of the time but we did not systematically test this.

• Fix a crash in benchexec for task with property but without task-definition file.
