-SimGrid (3.17) UNRELEASED (release target: September 22 2017)
+SimGrid (3.18) NOT RELEASED YET (target: December 24 2017)
+
+ S4U
+ - Link::name() is deprecated and will be removed in v3.21, use
+ Link::getCname() instead.
+ - Mailbox::getName() changed to return a std::string, use
+ Mailbox::getCname() instead to get a char*.
+ - Storage::getName() changed to return a std::string, use
+ Storage::getCname() instead to get a char*.
+
+ MSG
+ - Deprecate MSG_task_get_flops_amount(). Its semantic was weird:
+ before the start it returned the total amount of flops;
+ after it returned the ratio of remaining work. Split it:
+ MSG_task_get_initial_flops_amount() for first behavior
+ MSG_task_get_remaining_work_ratio() for the second one.
+ This fixes GitHub's #223 using PR #237. Thanks Michael Mercier.
+
+ XBT
+ - Define class simgrid::xbt::Path to manage file names.
+ - Removed unused functions:
+ - xbt/file.h: xbt_basename(), xbt_dirname(), xbt_getline()
+ - xbt/str.h: xbt_str_join()
+ - xbt/heap.h: use std::priority_queue or boost::heap instead
+
+ PLUGINS:
+ - New link_energy plugin for the consumption of the links.
+ - All of the operations on files and storage contents have been
+ packaged into a plugin (src/plugins/file_system). The current
+ public interface can be found in
+ include/simgrid/plugins/file_system.h
+ To use these functions you now have to initialize the plugin by
+ calling MSG_storage_file_system_init() just after calling
+ MSG_init() or sg_storage_file_system_init() just after creating
+ the Engine.
+
+ XML
+ - Remove the undocumented/untested tag <include>
+
+ TRACE
+ - Remove viva specific tracing as the tool is no longer maintained
+
+ Fixed bugs:
+ - #248: Kill of finished MSG processes leads to segfault
+
+SimGrid (3.17) Released October 8 2017
The Drained Leaks release: (almost) no known leaks despite the tests.
Even very long simulations will preserve your memory: our testsuite
- stresses SimGrid for over 45mn on fast machines, and there is only
- one single known leak, of about 4kb.
+ stresses SimGrid for over 45mn on fast machines for a coverage of
