ceasta 0.10.0

• search everything (ctrl+f, edit > search, the toolbar): functions, names, imports, exports,
  strings, comments and segments in one box - exact matches first, up / down / enter to jump,
  and strings say where they're used. the info panel's box searches its lists and the tabs
  count the matches. ceasta-cli search <file> <text> does the same from a terminal
• debugger: a steps box by the step buttons (and in the debug menu) - f7 / f8 run that many
  instructions at once without freezing the window; a breakpoint, a fault or the exit ends it
  early, and the output gets one line instead of one per instruction
• the ai server in the app: ai > connect an ai starts the mcp server for the open file and shows
  what to paste into claude code / cursor. the ai works on what you see - its renames, comments
  and breakpoints show up live, and its debug session is the window's debugger
• saving: nothing is saved behind your back any more. closing the window, closing the file or
  opening another one asks first (save / don't save / cancel), the title shows a * while there
  are unsaved changes, and file > save project as... writes a .ceasta project wherever you
  like - open it (ctrl+o or drop it on the window) to pick up where you left off
• mcp over http only answers programs on this machine: requests from web pages of other sites
  and dns-rebinding hosts are refused, and a stalled connection can't hold the server
• linux debugger: the program no longer inherits ceasta's open files and sockets

download

• ceasta-0.10.0-setup.exe - installer for windows 10/11 x64. installs for your user without admin rights, adds a start menu entry and (optionally) "open with ceasta" to the right-click menu.
• ceasta-0.10.0-windows-x64.zip - portable, unzip and run ceasta.exe.
• ceasta-cli-0.10.0-linux-x64.tar.gz - the command line tool for linux: analysis, disassembly, the decompiler, a terminal debugger (ceasta-cli dbg), binary diff, library signatures, lua scripting, and the mcp server (ceasta-cli mcp) for connecting an ai. the linux gui is experimental and not in this download - build it yourself (see the readme).

ceasta 0.9.0

• a built-in mcp server: connect an ai (claude code / desktop, cursor, ...) to the open binary
  • ceasta-cli mcp <file> (stdio) or --http <port>; read, decompile, xrefs, rename, comment
  • --allow-debug adds the debugger tools: breakpoints, stepping, registers, memory, and
    debug_call (call a function and get its result), debug_trace, debug_decompile_here
  • --allow-lua adds run_lua. see docs/mcp.md
• call a function in the running program: repl call, lua ceasta.dbg.call, mcp debug_call
• live pseudocode: stopped in a function, the current line is marked (repl dec, mcp)
• runtime xrefs: trace records the targets of indirect calls / jumps the program takes
• binary diff: ceasta-cli diff <old> <new> and the diff_binary mcp tool
• library signatures: sigmake / sigapply name known functions in a stripped binary
• project files: names / comments / breakpoints save to a committable <binary>.ceasta
• experimental linux gui (glfw + opengl3), off by default (-DCEASTA_LINUX_GUI=ON)

ceasta 0.8.2

• decompiler fixes - it could print code that doesn't do what the program does
  • values a later block reads were dropped: a loop could lose its counter increment, a function its return value
  • nothing reads a register after it changed any more, when an assignment has to be written out early
  • calls get their real arguments: functions in the binary are checked for what they read, and values a compiler keeps in registers across a call to a small function survive it
  • setcc, cmov, div / idiv, mul, rol / ror, bswap, popcnt are lifted (rax == 5, a ? b : c, / and %, __rol(x, 5)); anything else shows as __asm { ... } instead of vanishing
  • loops with more than one exit, top-tested loops that compute before their test, and tail calls (a jump into another function, or through a pointer) come out right
  • switch cases are written inside the switch, and functions whose result no caller reads are void
  • every goto has its label - a jump back to code that was already written had none
• the pseudocode screenshot shows the new switch output
• the linux download's release note mentions the terminal debugger
