| 3 * Version 1.2.2 released | |
| 4 * Fixed bug in qncmmva: utilization for M/M/m centers, m>1, was not correctly scaled to [0,1] | |
| 5 * Added warning to qncsmva to inform user about potential loss of accuracy due to load-dependent servers | |

| 11005 | 20 * Restructured the documentation |
| 11110 | 21 * Reduced space requirement for qncsmva() |
| 11207 | 22 * New function naming scheme; old function names are still |
| 23 available for compatibility with existing scripts, but will be | |
| 24 removed in the future. | |
| 25 * New functions qncmaba, qncmbsb, qncmcb, qnomaba for computing | |
| 26 performance bounds on multiclass networks | |

| 9621 | 38 |
| 9966 | 39 * Version 1.1.0 released |
| 9621 | 40 * Fixed bug in qnvisits() which made the function behave incorrectly |
| 41 under particular degenerate cases. | |
| 42 * Fixed bug in ctmc_exps() (wrong initial value in call to lsode) | |
| 9628 | 43 * ctmc_exps() can now also compute the expected sojourn time |
| 9621 | 44 until absorption for absorbing CTMCs. |
| 9628 | 45 * ctmc_exps() and ctmc_taexps() accept a scalar as second |
| 9625 | 46 argument; the old syntax is still supported, but may be deprecated |
| 47 in future releases. | |
| 9628 | 48 * ctmc_bd() now returns the infinitesimal generator matrix |
