   updating to a new Aya release less of a burden. These aliases are marked
   as deprecated since we'll likely remove them in a later release.

+### Bug Fixes
+
+ - <csr-id-ca0c32d1076af81349a52235a4b6fb3937a697b3/> Fill bss maps with zeros
+   The loader should fill bss maps with zeros according to the size of the
+   ELF section.
+   Failure to do so yields weird verifier messages as follows:
+   
+   ```
+   cannot access ptr member ops with moff 0 in struct bpf_map with off 0 size 4
+   ```
+   
+   Reference to this in the cilium/ebpf code is here [1].
+   I could not find a reference in libbpf.
+
 ### Other

+ - <csr-id-366c599c2083baf72c40c816da2c530dec7fd612/> cgroup_iter_order NFPROTO* nf_inet_hooks
+   Adds the following to codegen:
+   - `bpf_cgroup_iter_order`: used in `bpf_link_info.iter.group.order`
+   - `NFPROTO_*`: used in `bpf_link_info.netfilter.pf`
+   - `nf_inet_hooks`: used in `bpf_link_info.netfilter.hooknum`
+   
+   Include `linux/netfilter.h` in `linux_wrapper.h` for `NFPROTO_*` and
+   `nf_inet_hooks` to generate.

   Adds detection for whether a field is available in `MapInfo`:

+
+### New Features
+
+ - <csr-id-8c79b71bd5699a686f33360520aa95c1a2895fa5/> Rename Bpf to Ebpf
+   And BpfLoader to EbpfLoader.
+   This also adds type aliases to preserve the use of the old names, making
+   updating to a new Aya release less of a burden. These aliases are marked
+   as deprecated since we'll likely remove them in a later release.
+
+### Other
+
+ - <csr-id-fbb09304a2de0d8baf7ea20c9727fcd2e4fb7f41/> revamp MapInfo be more friendly with older kernels
+   Adds detection for whether a field is available in `MapInfo`:
+   - For `map_type()`, we treturn new enum `MapType` instead of the integer
+     representation.
+   - For fields that can't be zero, we return `Option<NonZero*>` type.
+   - For `name_as_str()`, it now uses the feature probe `bpf_name()` to
+     detect if field is available.
+     Although the feature probe checks for program name, it can also be
+     used for map name since they were both introduced in the same commit.
+ - <csr-id-88f5ac31142f1657b41b1ee0f217dcd9125b210a/> revamp ProgramInfo be more friendly with older kernels
+   Purpose of this commit is to add detections for whether a field is
+   available in `ProgramInfo`.
+   - For `program_type()`, we return the new enum `ProgramType` instead of
+     the integer representation.
+   - For fields that we know cannot be zero, we return `Option<NonZero*>`
+     type.
+   - For `name_as_str()`, it now also uses the feature probe `bpf_name()`
+     to detect if field is available or not.
+   - Two additional feature probes are added for the fields:
+     - `prog_info_map_ids()` probe -> `map_ids()` field
+     - `prog_info_gpl_compatible()` probe -> `gpl_compatible()` field
+   
+   With the `prog_info_map_ids()` probe, the previous implementation that
+   I had for `bpf_prog_get_info_by_fd()` is shortened to use the probe
+   instead of having to make 2 potential syscalls.
+   
+   The `test_loaded_at()` test is also moved into info tests since it is
+   better related to the info tests.
+ - <csr-id-1634fa7188e40ed75da53517f1fdb7396c348c34/> add conversion u32 to enum type for prog, link, & attach type
+   Add conversion from u32 to program type, link type, and attach type.
+   Additionally, remove duplicate match statement for u32 conversion to
+   `BPF_MAP_TYPE_BLOOM_FILTER` & `BPF_MAP_TYPE_CGRP_STORAGE`.
+   
+   New error `InvalidTypeBinding<T>` is created to represent when a
+   parsed/received value binding to a type is invalid.
+   This is used in the new conversions added here, and also replaces
+   `InvalidMapTypeError` in `TryFrom` for `bpf_map_type`.
+ - <csr-id-b513af12e8baa5c5097eaf0afdae61a830c3f877/> add archs powerpc64 and s390x to aya
+   bpfman, a project using aya, has a requirement to support powerpc64 and
+   s390x architectures. Adding these two architectures to aya.
+ - <csr-id-b06ff402780b80862933791831c578e4c339fc96/> Generate new bindings
+
+### Test
+
+ - <csr-id-4dc4b5ccd48bd86e2cc59ad7386514c1531450af/> adjust test to not use byte arrays
+   Where possible, replace the hardcoded byte arrays in the tests with the
+   structs they represent, then convert the structs to byte arrays.
+ - <csr-id-eef7346fb2231f8741410381198015cceeebfac9/> adjust test byte arrays for big endian
+   Adding support for s390x (big endian architecture) and found that some
+   of the unit tests have structures and files implemented as byte arrays.
+   They are all coded as little endian and need a bug endian version to
+   work properly.
+
+### New Features (BREAKING)
+
+ - <csr-id-fd48c55466a23953ce7a4912306e1acf059b498b/> Rename BpfRelocationError -> EbpfRelocationError
+ - <csr-id-cf3e2ca677c81224368fb2838ebc5b10ee98419a/> Rename BpfSectionKind to EbpfSectionKind
