28 September 2015: Wouter
- MAX_TARGET_COUNT increased to 64, to fix up sporadic resolution
failures.
- tag for 1.5.5rc1 release.
- makedist.sh: pgp sig echo commands.
25 September 2015: Wouter
- Fix unbound-control flush that does not succeed in removing data.
22 September 2015: Wouter
- Fix config globbed include chroot treatment, this fixes reload of
globs (patch from Dag-Erling Smørgrav).
- iana portlist update.
- Fix #702: New IPs for for h.root-servers.net.
- Remove confusion comment from canonical_compare() function.
- Fix #705: ub_ctx_set_fwd() return value mishandled on windows.
- testbound selftest also works in non-debug mode.
- Fix minor error in unbound.conf.5.in
- Fix unbound.conf(5) access-control description for precedence
and default.
31 August 2015: Wouter
- changed windows setup compression to be more transparent.
28 August 2015: Wouter
- Fix #697: Get PY_MAJOR_VERSION failure at configure for python
2.4 to 2.6.
- Feature #699: --enable-pie option to that builds PIE binary.
- Feature #700: --enable-relro-now option that enables full read-only
relocation.
24 August 2015: Wouter
- Fix deadlock for local data add and zone add when unbound-control
list_local_data printout is interrupted.
- iana portlist update.
- Change default of harden-algo-downgrade to off. This is lenient
for algorithm rollover.
13 August 2015: Wouter
- 5011 implementation does not insist on all algorithms, when
harden-algo-downgrade is turned off.
- Reap the child process that libunbound spawns.
11 August 2015: Wouter
- Fix #694: configure script does not detect LibreSSL 2.2.2
4 August 2015: Wouter
- Document that local-zone nodefault matches exactly and transparent
can be used to release a subzone.
3 August 2015: Wouter
- Document in the manual more text about configuring locally served
zones.
- Fix 5011 anchor update timer after reload.
- Fix mktime in unbound-anchor not using UTC.
30 July 2015: Wouter
- please afl-gcc (llvm) for uninitialised variable warning.
- Added permit-small-holddown config to debug fast 5011 rollover.
24 July 2015: Wouter
- Fix #690: Reload fails when so-reuseport is yes after changing
num-threads.
- iana portlist update.
21 July 2015: Wouter
- Fix configure to detect SSL_CTX_set_ecdh_auto.
- iana portlist update.
20 July 2015: Wouter
- Enable ECDHE for servers. Where available, use
SSL_CTX_set_ecdh_auto() for TLS-wrapped server configurations to
enable ECDHE. Otherwise, manually offer curve p256.
Client connections should automatically use ECDHE when available.
(thanks Daniel Kahn Gillmor)
18 July 2015: Willem
- Allow certificate chain files to allow for intermediate certificates.
(thanks Daniel Kahn Gillmor)
13 July 2015: Wouter
- makedist produces sha1 and sha256 files for created binaries too.
9 July 2015: Wouter
- 1.5.4 release tag
- trunk has 1.5.5 in development.
- Fix #681: Setting forwarders with unbound-control forward
implicitly turns on forward-first.
29 June 2015: Wouter
- iana portlist update.
- Fix alloc with log for allocation size checks.
