Introduction

Release 7.1.1 is a bugfix release in terms of upgrading from 7.1.0. Only the names have changed, from "710" to "711".

Upgrade Paths

It is not possible to upgrade from 6.x.x to 7.x.x. Code has to be rewritten. However, 6.0.1 and 6.1.1 can be compiled and linked into the same code base as 7.x.x, so existing code does not need to be migrated.

Upgrading from 7.0.0 to 7.1.1 involves accomodating the API name change for the singly-linked ordered list and the queue, and the change to the freelist init function to accomodate the new elimination array.

Upgrading from 7.1.0 to 7.1.1 involves a global search and replace for "lfds710" to "lfds711", upper-case and lower-case.

Known Issues

No known issues.

libshared

  • The Linux kernel abstraction layer port is incomplete.

libtest

No known issues.

libbenchmark

  • The Linux kernel abstraction layer port is incomplete.
  • The btree test is a bit unfair - it does a bit more work as the number of logical cores increases, so as such, it is underplaying performance for higher core counts.

No known issues.
