+
+### New Features
+
+ - <csr-id-5478cac008471bdb80aa30733e4456b70ec1a5bd/> Implement TCX
+   This commit adds the initial support for TCX
+   bpf links. This is a new, multi-program, attachment
+   type allows for the caller to specify where
+   they would like to be attached relative to other
+   programs at the attachment point using the LinkOrder
+   type.
+ - <csr-id-110a76cb9a1b2ab5c5ad3b6c0828a4ae670e67a0/> Provide a deprecated `BpfError` alias
+ - <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.
+
+### Bug Fixes
+
+ - <csr-id-3d57d358e40591acf23dfde740697fbfff026410/> Fix PerfEventArray resize logic
+   There was a logic bug in the previously merged patch where we
+   set the correctly calculated max_entries size with the original.
+   
+   To fix this and prevent regressions a unit test was added.
+   This highlighted that the original map definition needs to be
+   mutated in order for the max_entries change to be properly applied.
+   
+   As such, this resize logic moved out of aya::sys into aya::maps
+ - <csr-id-25d986a26d9c88cd499a8b795054d583f01476b2/> Set PerfEventArray max_entries to nCPUs
+   Both libbpf and cilium/ebpf have will set the max_entries of a
+   BPF_MAP_TYPE_PERF_EVENT_ARRAY to the number of online CPUs if
+   it was omitted at map definition time. This adds that same
+   logic to Aya.
+ - <csr-id-38d8e32baa5a4538de9daa6fae634aea6372573c/> fix panic when creating map on custom ubuntu kernel
+ - <csr-id-5e13283f59b0c3b4cb47de1e31d8d0960e80b4cc/> fix rustdocs-args ordering in taplo to -D warnings
+   This fixes the current rustdoc build error by correcting the ordering of
+   `rustdoc-args` to `-D warnings`. Additionally, this also removes the
+   `recorder_arrays` field (defaults to false) so that the order is not
+   modified, which is what caused the error in the first place.
+
+### Other
+
+ - <csr-id-c44f8b0f5bddd820a4a98cff293126c0146b827a/> use FdLink in SockOps programs
+ - <csr-id-02d1db5fc043fb7af90c14d13de6419ec5b9bcb5/> remove unwrap and NonZero* in info
+   Addresses the feedback from #1007:
+   - remove panic from `unwrap` and `expect`
+   - Option<NonZero*> => Option<int> with `0` mapping to `None`
+ - <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-cb8e47880082ccfcd75b02209b686e15426e9b6a/> improve integration tests for info API
+   Improves the existing integraiton tests for `loaded_programs()` and
+   `loaded_maps()` in consideration for older kernels:
+     - Opt for `SocketFilter` program in tests since XDP requires v4.8 and
+       fragments requires v5.18.
+     - For assertion tests, first perform the assertion, if the assertion
+       fails, then it checks the host kernel version to see if it is above
+       the minimum version requirement. If not, then continue with test,
+       otherwise fail.
+       For assertions that are skipped, they're logged in stderr which can
+       be observed with `-- --nocapture`.
+   
+   This also fixes the `bpf_prog_get_info_by_fd()` call for kernels below
+   v4.15. If calling syscall  on kernels below v4.15, it can produce an
+   `E2BIG` error  because `check_uarg_tail_zero()` expects the entire
+   struct to all-zero bytes (which is caused from the map info).
+   
+   Instead, we first attempt the syscall with the map info filled, if it
+   returns `E2BIG`, then perform syscall again with empty closure.
+   
+   Also adds doc for which version a kernel feature was introduced for
+   better  awareness.
+   
+   The tests have been verified kernel versions:
+     - 4.13.0
+     - 4.15.0
+     - 6.1.0
+ - <csr-id-cd1db86fd490b3c0f03229bd8999a2e67ccecfc4/> adjust bpf programs for big endian
+   In aya/src/sys/bpf.rs, there are several simple bpf programs written as
+   byte arrays. These need to be adjusted to account for big endian.
+ - <csr-id-a25f501ecebaceaacdd1212fac34f528b51ad0fd/> expose run_time_ns and run_cnt fields in ProgramInfo
+   Added functions to expose `run_time_ns` & `run_cnt` statistics from
+   ProgramInfo/bpf_prog_info.
+ - <csr-id-fa6af6a20439cccd8ab961f83dce545fb5884dd4/> add BPF_ENABLE_STATS syscall function
+   Add bpf syscall function for BPF_ENABLE_STATS to enable stats tracking
+   for benchmarking purposes.
+   
+   Additionally, move `#[cfg(test)]` annotation around the `Drop` trait
+   instead. Having separate functions causes some complications when
+   needing ownership/moving of the inner value `OwnedFd` when `Drop` is
+   manually implemented.
+ - <csr-id-d413e2f285643cbeb665fd3c517e2c9d93d45825/> :programs::uprobe: fix bad variable name
+   The variable fn_name was very much *not* the fn_name, but rather the
+   object file path.
+ - <csr-id-462514ed4c4c06e9618d029a57708c7fa14ab748/> adjust symbol lookup tests for object crate alignment requirements
+   The object::File::parse API requires parameter to be aligned with 8 bytes.
+   Adjusted the Vec in the tests with miri to meet this requirement.
+ - <csr-id-e6e1bfeb58ac392637061640365b057182ee1b39/> add symbol lookup in associated debug files
+   This change enhances the logic for symbol lookup in uprobe or uretprobe.
+   If the symbol is not found in the original binary, the search continues
+   in the debug file associated through the debuglink section. Before
+   searching the symbol table, it compares the build IDs of the two files.
+   The symbol lookup will only be terminated if both build IDs exist and do
+   not match. This modification does not affect the existing symbol lookup
+   logic.
+ - <csr-id-b06ff402780b80862933791831c578e4c339fc96/> Generate new bindings
+ - <csr-id-a4e68ebdbf0e0b591509f36316d12d9689d23f89/> include license in crate workspace
+   This PR includes the licenses files in the crate workspace subdirectory.
+   Without this, they won't be showing on crates.io and would be giving out
+   errors on tooling such as rust2rpm.
