version: dnscache 0.50, alpha. not released yet.
19991223
version: dnscache 0.60, alpha.
19991224
internal: dns_sortip() takes length argument.
api: dns_ip4() sorts output. currently this means just random.
api: added socket_bind4_reuse(). removed reuse from bind4().
ui: used bind4_reuse() for port 53, bind4() otherwise.
internal: eliminated some unused variables.
internal: prototypes in cdb.h, cdbmake.h, cdbmss.h.
internal: prototypes in case.h, env.h, fmt.h, scan.h, str.h.
internal: prototypes in stralloc.h.

api: dns_ip4() checks for (strings of) IP addresses.
20000106
port: Solaris needs /dev/udp, not just /dev/tcp. impact:
dnscache and tinydns would stop immediately under
Solaris. fix: create /dev/udp in configure; and have
tinydns create socket before chroot. tnx Louis Theran.

version: dnscache 0.75, beta.
20000118
internal: address* -> address_* in pickdns-data.c.

under the old name uses dns_resolvconfrewrite().
internal: cleaned up log.h.
20000121
port: the gcc 2.95.2 -O2 optimizer can destroy parameters in a
function that calls another function with a long long
argument. impact: gcc 2.95.2 kills dnscache in
log_query(). fix: pass log_stats() inputs by reference,
and pass uint64's through a variable inside log.c.

should work around the Squid parsing bug reported by
Stuart Henderson.
20000211

ui: dns_transmit_get() pauses after server failure, if udploop
is 2.
internal: sped up name handling in response.c.
20000223
ui: dnscache ignores some garbage in queries: AA, !RD, RA, Z,
RCODE, AN, AU, AR. (note that responses still say RD.)

Chris Cappuccio.
20000227
ui: tinydns-data uses server name instead of a.ns.domain for
automatic primary in SOA. tnx Frank Tegtmeyer.
20000228
bug: axfrdns doesn't set aa bit in responses. impact: named-xfer
refuses to do zone transfers from axfrdns. fix: set aa
bit. tnx Peter Hunter.

tnx Frank Tegtmeyer.
version: DNScache 0.92, gamma.
20000314
portability problem: the poll() emulation in RedHat 5.1 doesn't
clear revents when select() returns 0. tnx Petr Novotny.
impact: dns_transmit_get() never times out;
dns_resolve() busy-loops. fix: clear revents before
poll().
20000315

version: DNScache 0.93, gamma.
20000323
ui: dns_rcip() accepts 0.0.0.0 in /etc/resolv.conf as 127.0.0.1.
tnx Chris Saia.

version: DNScache 1.00.
20000914

copy O_NONBLOCK. tnx Pavel Kankovsky. impact: with these
kernels, dnscache hangs if a TCP connection times out.
fix: ndelay_on() after accept().
ui: dnscache discards non-recursive queries.
ui: *-conf use envdir in */run.
internal: reorganized seed_addtime() calls in dnscache-conf.

still pauses after connection-refused when udploop is 2.
version: djbdns 1.01.
20000922
portability problem: Linux distributions use bash as /bin/sh;
bash destroys $UID. dorks. impact: dnscache and axfrdns
run as root. fix: envdir, then sh, then envuidgid. but
/bin/sh really has to stop polluting the environment.
20000923
ui: install /etc/dnsroots.global. dnscache-conf tries
dnsroots.local, then dnsroots.global.
ui: no longer install home/etc/dnscache.

table is full, and oldest TCP connection if TCP table is
full.
ui: dnscache reports broken pipe when a TCP client sends FIN.
20001228
ui: dnstrace supports dd.
ui: dnscache logs stats when it handles 1.0.0.127.in-addr.arpa.

ui: pickdns responds to MX queries. tnx Mike Batchelor.
internal: added const at various places.
internal: removed some unused variables.
internal: used time_t in tai_now.c.

ui: dnscache no longer caches SERVFAIL. per-ip is obviously the
way to go.

answer section, and truncates the list after 8 records.

20010114
internal: documented the tinydns data.cdb format.
ui: tinydns-data, tinydns, tinydns-get, axfrdns support client
differentiation.
ui: dnsqr aborts if it is given an extra argument.
20010117
ui: dnstracesort removes duplicate lines.
ui: dnstracesort prints glue.
ui: dnstrace uses a ``start'' IP address for the root glue.
20010121
version: djbdns 1.04.
20010206
internal: response_query() takes a class argument.
internal: query_start() takes a class argument.
internal: packetquery() takes a class argument.
ui: tinydns et al., axfrdns, and dnscache repeat qclass * in
response to bogus * queries. tnx Mike Batchelor.

20010211
ui: servers print starting message.
internal: some respond() declarations.
