| 37 -- A time line for Lucid Emacs/XEmacs is | |
| 38 | |
| 2517 | 39 Version 19.0 shipped with Energize 1.0, April 1992. |
| 40 Version 19.1 released June 4, 1992. | |
| 41 Version 19.2 released June 19, 1992. | |
| 42 Version 19.3 released September 9, 1992. | |
| 43 Version 19.4 released January 21, 1993. | |
| 44 Version 19.5 released February 5, 1993. This was a repackaging of 19.4 with a | |
| 45 few bug fixes and shipped with Energize 2.0. It was a trade-show giveaway | |
| 46 and never released to the net. | |
| 47 Version 19.6 released April 9, 1993. | |
| 48 Version 19.7 was a repackaging of 19.6 with a few bug fixes and | |
| 442 | 49 shipped with Energize 2.1. Never released to the net. |
| 2517 | 50 Version 19.8 released September 6, 1993. (Epoch merger, preliminary I18N |
| 51 support) | |
| 52 Version 19.9 released January 12, 1994. (Scrollbars, Athena.) | |
| 53 Version 19.10 released May 27, 1994. Known as "Lucid Emacs" when | |
| 54 shipped by Lucid, and as "XEmacs" when shipped by Sun; but Lucid | |
| 55 went out of business a few days later and it's unclear very many | |
| 56 copies of 19.10 were released by Lucid. (Last release by Jamie Zawinski.) | |
| 57 Version 19.11 (first XEmacs) released September 13, 1994. | |
| 58 Version 19.12 released June 23, 1995. | |
| 59 Version 19.13 released September 1, 1995. | |
| 60 Version 19.14 released June 23, 1996. | |
| 61 Version 20.0 released February 9, 1997. | |
| 62 Version 19.15 released March 28, 1997. | |
| 63 Version 20.1 (not released to the net) April 15, 1997. | |
| 64 Version 20.2 released May 16, 1997. | |
| 65 Version 19.16 released October 31, 1997; retiring of v19 series. | |
| 66 Version 20.3 (the first stable version of XEmacs 20.x) released November 30, | |
| 67 1997. | |
| 68 Version 20.4 released February 28, 1998. (Jamie claims this version is the | |
| 69 "first reasonably stable release with MULE support" and says that "XEmacs | |
| 70 'core' and 'packages' now packaged separately.") | |
| 71 Version 21.0-pre5 released July 18, 1998. (Jamie says "Numbering scheme goes | |
| 72 wonky due to switch to stable + unstable branches.") | |
| 73 Version 21.0.60 released December 10, 1998. (The version naming scheme was | |
| 74 changed at this point: [a] the second version number is odd for stable | |
| 75 versions, even for beta versions; [b] a third version number is added, | |
| 76 replacing the "beta xxx" ending for beta versions and allowing for | |
| 77 periodic maintenance releases for stable versions. Therefore, 21.0 was | |
| 78 never "officially" released; similarly for 21.2, etc.) | |
| 79 Version 21.0.61 released January 4, 1999. | |
| 80 Version 21.0.63 released February 3, 1999. | |
| 81 Version 21.0.64 released March 1, 1999. | |

| 83 Version 21.0.66 released March 12, 1999. | |
| 84 Version 21.0.67 released March 25, 1999. | |
| 85 Version 21.1.2 released May 14, 1999; on comp.emacs, May 28. (This is | |
| 788 | 86 the followup to 21.0.67. The second version number was bumped to indicate |
| 87 the beginning of the "stable" series.) | |
| 2517 | 88 Version 21.1.3 released June 26, 1999. |
| 89 Version 21.1.4 released July 8, 1999. | |
| 90 Version 21.1.6 released August 14, 1999. (There was no 21.1.5.) | |

| 3902 The line above is original. Unfortunately, when an error is tripped | |
| 3903 inside of the handler (e.g. during Fbacktrace()), and the handler for | |
| 3904 the handler is invoked, it correctly notices that something is amiss | |
| 3905 and it should just return -- but it returns EXCEPTION_CONTINUE_SEARCH, | |
| 3906 which causes the debugger to be invoked debugging the handler code in | |
| 3907 this function -- and WITH THE STACK UNWOUND so that you see main() | |
| 3908 calling mswindows_handle_hardware_exceptions(), calling Fbacktrace(), | |
| 3909 and a crash a couple of frames in -- AND NO SIGN OF THE ORIGINAL CRASH! | |
| 3910 | |
| 3911 There's some real weirdness going on in the stack handling -- unlike | |
| 3912 in Unix, where further crashes just keep adding to the stack, it seems | |
| 3913 that under the structured-exception-handling, the stack can actually | |
| 3914 bounce back and forth between the full stack at the location of the | |
| 3915 exception and the unwound stack at the place where the __try clause was | |
| 3916 established. I don't completely understand it. What I do know is that | |
| 3917 returning EXCEPTION_EXECUTE_HANDLER on nested crash has the effect of | |
| 3918 aborting execution of the handler and going back to the outer filter | |
| 3919 function, which returns EXCEPTION_CONTINUE_SEARCH and everything is | |
| 3920 hunky-dorey -- your debugger sees a crash at the right location with | |
| 3921 the right stack. | |
| 3922 | |
| 3923 I'm leaving in the trickier Unix-like code in the handler; someone who | |
| 3924 understands better than me how the stack works in these handlers could | |
| 3925 fix it up more. As it is, it works pretty well, so I'm not likely to | |
