+# Change Log
+
+## [Bloaty McBloatface v1.1](https://github.com/google/bloaty/releases/tag/v1.1) (2020-05-23)
+
+### Added
+
+* **Source Filtering**: Bloaty can now filter the results based on a regex
+  match. See "Source filter" in [README.md](README.md) for details. (#177)
+* **Show only File or VM**: It is possible to restrict the output to show only
+  "VM SIZE" or "FILE SIZE" by passing `--domain=vm` or `--domain=file`. (#165)
+
+### Fixed
+
+* **Use system deps in CMake build**: The CMake build can now use system deps
+  for protobuf, capstone, and re2 if they are present. Hopefully this will make
+  Bloaty easier to package in package managers. (#155)
+* **DWARF 4 Support**: Fixed one place in Bloaty that was not accepting DWARF 4.
+  (#166)
+* **DWARF fix**: Added support for `DW_FORM_ref_udata`. (#197)
+* **Big-endian fix**: Added missing byte swapping when getting the build ID for
+  a big-endian binary. (#182)
+* **WASM demangling**: WASM symbols are now properly demangled. (#149)
+* **New WASM sections**: Added support for new DataCount and Event sections
+  in WASM. (#178)
+* **Scaling fixes**: Fixed integer overflow in 32-bit builds, and other issues
+  that arise when using Bloaty with many files and/or large files. (#193)
+* **Improved coverage**: Bloaty now properly attributes `.eh_frame` in object
+  files, and attributes ELF headers to the corresponding section. (#168)
+* **CSV escaping**: Bloaty now properly escapes CSV output when a field contains
+  a comma or double quote. (#174)
+
+### Changed
+
+* **File size column moved left**: In the default output, the file size now
+  appears on the left. This means that all numbers are now on the left, which
+  leads to more readable output when viewing in a proportional font or in a
+  limited-width window.
+
+  Old:
+  ```
+       VM SIZE                         FILE SIZE
+   --------------                   --------------
+     0.0%       0 .debug_info        7.97Mi  29.5%
+     0.0%       0 .debug_loc         6.40Mi  23.7%
+  ```
+
+  New:
+  ```
+      FILE SIZE        VM SIZE    
+   --------------  -------------- 
+    30.0%  8.85Mi   0.0%       0    .debug_info
+    24.7%  7.29Mi   0.0%       0    .debug_loc
+  ```
+
+  This shouldn't cause breakage, as anything consuming Bloaty's output
+  programmatically should be using `--csv` or `--tsv`. (#165)
+* **ELF Segment labels now contain index**: Previously ELF segment labels looked
+  like `LOAD [RW]` with segment flags only. Now they also contain the segment
+  index, eg. `LOAD #1 [RW]`, so the output can distinguish between different
+  segments with the same flags. (#159)
+
+### Security
+
+Bloaty should not be considered fully hardened against malicious binaries.  This
+is one of the major reasons why Bloaty is not offered as an in-process library,
+and should only be used through its command-line interface in a dedicated
+address space. If you do not trust the input, further process sandboxing is
+advisable.
+
+However we do perform fuzzing of the parsers, and fix and crash bugs that are
+found by fuzzing.
+
+* **Fixed crash bugs found by fuzzing** (#173, #175)
+
+## [Bloaty McBloatface v1.0](https://github.com/google/bloaty/releases/tag/v1.0) (2018-08-07)
+
+This is the first formal release of Bloaty.
+
+Changes since Bloaty was [first announced in Nov
+2016](http://blog.reverberate.org/2016/11/07/introducing-bloaty-mcbloatface.html):
+
+* **Much better coverage / data quality**: Bloaty now properly attributes
+  sections of the binary like the symbol table, debugging information,
+  relocations, and frame unwinding info. We even disassemble the binary looking
+  for references to anonymous data members that do not have symbol table
+  entries. This all means higher quality output, and much less of the binary is
+  attributed to `[None]`.
+* **Native Mach-O support**: Bloaty can now parse Mach-O files directly,
+  instead of shelling out to other programs. The result is much faster and
+  higher-quality output for Mach-O. Also the data sources that require debug
+  info (like `-d compileunits`) now work with Mach-O.
+* **WebAssembly support (EXPERIMENTAL)**: Bloaty can analyze sections and
+  symbols in binary WebAssembly files.
+* **Native C++ Demangling**: Bloaty can now demangle C++ symbols without
+  shelling out to `c++filt`. There are two separate demangling modes, one which
+  strips all template parameters and parameter/return types (`shortsymbols`) and
+  one that returns full demangled names (`fullsymbols`).
+* **Profiling stripped binaries**: Bloaty can read symbols and debug info from
+  separate files. This allows you to profile stripped binaries.
+* **Parallel file parsing**: If you pass multiple files to Bloaty, it will
+  scan them in parallel. If you are parsing lots of files and have lots of CPUs,
+  this can save a lot of time.
+* **Configuration files**: All options you can specify on the command-line can
+  be put in a configuration file instead (and vice versa). This is helpful if
+  the options might otherwise overflow the command-line (for example, if you
+  are parsing thousands of files). It also lets you save bits of configuration
+  to a file for reuse.
+* **Custom data sources**: you can create your own data sources by applying
+  regexes to the built-in sources. This lets you bucket symbols, source files,
+  etc. in ways that make sense for your project.
+* **CSV/TSV output**: this is a robust way to parse Bloaty's output and use it
+  in other programs. (The default, human-readable output is not designed to be
+  parsed and its format may change in backward-incompatible ways).
+* **Lots of bugfixes**: Fixed lots of bugs that people reported in various
+  platforms and configurations. Bloaty is fuzzed regularly now, and this has
+  led to many bugfixes also.
