Testing is still needed. Also only 'optional' extension fields
are supported now, 'repeated' fields are not yet supported.

If you have a message that defined as empty, but attempt to decode a
message that has one or more unknown fields then pb_decode fails. The
method used to count the number of required fields counts 1 required
field because the default type of PB_LAST_FIELD is PB_HTYPE_REQUIRED.

Also add note about the 'packed' message option being incompatible
with CPUs that do not support unaligned access.

Update issue 77
Status: FixedInGit

Patch from Michael Haberler.

If the null terminator is not present, string will be limited to the
data size of the field.

If you are still using the pb_enc_string (deprecated since 0.1.3) from
callbacks, now would be an excellent time to stop. The pb_field_t for
the callback will not contain proper data_size. Use pb_encode_string()
instead.

Fix suggested by Henrik Carlgren. Added also unit test for the bug.

Patch from dch.

The arg field can be used to store the field presence from inside
the callback. Furthermore, having the has_ field for encoding callbacks
would be more annoying than useful.

Update issue 70
Status: FixedInGit

NOTE: This change breaks backwards-compatibility by default.
If you have old callback functions, you can define PB_OLD_CALLBACK_STYLE
to retain the old behaviour.

If you want to convert your old callbacks to new signature, you need
to do the following:

1) Change decode callback argument to   void **arg
      and encode callback argument to   void * const *arg.

2) Change any reference to arg into *arg.

The rationale for making the new behaviour the default is that it
simplifies the common case of "allocate some memory in decode callback".

This allows replacing the C99 standard include file names with
a single system-specific file. It should provide all the necessary
system functions (typedefs, memset, memcpy, strlen).

This avoids a name clash when compiling as Linux kernel module.

Update issue 12
Still needs documentation.

pb_field_next() would access past the fields array.

Enable -fstack-protector-all to detect any stack smashing bugs. Also
use test_decode3 for maximal vulnerable surface.

Note: the bug only applies to empty message types. Empty messages
of non-empty message types are not affected.
