This is to report more correct + reconnect events when it comes to DoT, because the connection can be + lost while negotiating TLS. + + Lastly, additional tests has been added for the network code. + + d9e5663 net test + 22f49df network tests + 8e5b56e reconnect + +2020-03-22 Jerry Lundström + + Release 2.5.1 + + This release re-adds support for TYPEnnn and ANY in the datafile, this + was missed during the removal of the dependency on BINDs development + libraries in v2.4.0. + + Also note that with v2.5.0, this software now depends on Concurrency + Kit (ck) for atomic operations. + + 924e6ea ANY + 0a444c0 TYPEnnn + 2021-03-12 Jerry Lundström Release 2.5.0 |
