Features added

Not yet released

• Makefile for rs6000 fixed. (rs6000 cc does not have good -o flag). Binary available for rs6000 again.

16 Oct 92: Version 1.3a

• SOURCE command prefix allows printing, pipiping etc postscript source without formatting. SOURCE PRINT prints a postscript file. SOURCE > allows the original source to be saved.
• -listrefs option allow noninteractive output to be followed by lists of addresses of documents referred to.
• MANUAL command takes a hypertext jump straight to the latest version of the online manual. (HELP is still local slightly context-sensitive help).

Oct 92 version 1.2l

• Bug in Gopher access removed.
• Now uses common code library

version 1.2k

• Default port number changed to 80 ****.

18 May 92 version 1.2h

• PS command added to print document on local printer attached to a terminal. Special compilation flag SLAVE_PRINTER.
• BUG FIX: Crashes on some machines only fixed (malloc length error on HTTP.c.)

version 1.2f

• Bug fix: telnet under unix: -l option was put AFTER the host name. Fixed 27-Mar-92.

Version 1.2e

• New command: 'Verbose' toggles verbose mode on/off as per '-v' command switch.
• New command: for Unix, 'cd' or 'lcd' changes the local working directory (as in FTP clients).
• Command input handled more efficiently. Should use readline() in the future, with completion on anchor names..
• Some minor bug fixes.

Version 1.2d

• COMMENT tag introduced for future use only.
• Speed improvement: Use of a hash table for document names improves load time especially of documents with many links.

Version 1.2c

• Bug fix: unknown tags without attributes caused text to be skipped until the end of the next tag. This lead to missing information (like phone numbers! ) in CERN yellow pages listing and a strange format for the xfind server.

Version 1.2b

Version 1.2a

• Feature: the -source option makes www load the unparsed source from HTML servers. See details ...
• Tags MENU and DIR introduced for future use.
• Bug fix: The style was not set until a style change occured: therefore, formatting of any text before a heading etc was wrong (no paragraph spacing, indents, etc).
• Bug fix: Newlines in HTML source are not taken as blanks if they follow other white space. This caused initial blanks on some paragraphs when a newline followed a tag.

Feb 12 1992: Version 1.2

• Binaries generated for unix and vms hosts, for general announcement. Code fixes for compilation on the various platforms.

Version 1.1c

• www can be used as a filter: The - option (a dash by itself) makes it take HTML data from stdin. See details
• FTP directories contain pointers back to their parent directory.
• Bug fix: News access didn't work on little-endian machines (VAX etc).
• Bug fix: VMS descrip.mms file was not complete.

Version 1.1b

• Bug fix: HTBrowse.h missing from source release.

Version 1.1a

• Bug fix: news server address always taken as "cernvax" : see documentation

January 1992 Version 1.1

• "Gopher" protocol added to allow access to those campus-wide systems using that protocol.
• "Telnet:" access added for information system which don't have a server at all;
• Allows gateways to be defined for arbitrary new (or old) naming schemes, eg setenv WWW_wais_GATEWAY //node:port/
• Bug fixes: the -n option didn't work properly in v1.0

Version 1.0 (released as alpha test only)

• New archiecture, more modularity.
• "News" access added: picks up news using NNTP as the NeXT W3 browser does.
• Forward and reverse scrolling.
• "Next" and "Previous" commands added to allow to move to next article in a list.
• Bug fix: Searches are now only allowed on indexes.

Version 14a

• Logfile option -l, and -h allows remote usage to be logged. (Existed in version 14, but bug in that log file was all one line!)
• If telnet used, default logfile /usr/adm/www-log- is used even though no -l logfileroot is specified.

November 1991 version 0.14

• The `Recall' command now displays references as `R 1', `R 2', etc. instead of just `1', `2', etc. so the user is reminded to type `R <number>'.
• An out-of-range reference number will launch a keyword search if applicable. For instance, in the phone book, you can now type directly `3755' instead of `K 3755'.
• New command : `(G)OTO <address>' jumps to the document specified by its hypertext address. The address may be absolute or relative to the current node.
• Clear screen after user input for NEWLIB and VM. NEWLIB-special source put in. VM version defaults to home page on //info.cern.ch.
• Entity handling <., >. and &. put in for text and TITLE fields.
• Bug fix: CR now ignored in remote FTP files which used to be displayed double-spaced.
• Bug fix: tabs in plain text were displayed as newlines! Now to next multiple of 8 columns.

version 0.12

• -a xxx option now allows the anchor format to be specified. The old -a option for anchor supression is renamed -na.
• Bug fix: occasional crash when going "back".
• Bug fix with the -n command line option. In non interactive mode the prompt was still produced.
• Now treats '\r' characters as '\n' characters.
• Reproduces last line of page at the top of the next page if a paragraph is split between them.
• Bug fix in FTP handling as for NeXTStep editor . (Could not access some sites).
• HTTP host addresses may now contain a port number after a colon to override the default.

15 August 1991 version 0.11

• You can read the address of the current document in the HELP information.
• MVS and VM only: Line width reduced to 78 characters.

July 91 version 0.10

• Bug fix for TOP commmand. Now functions correctly, and data is only buffered and formatted when the user requires more text, hence saving time.
• Can pick up on the users home environment, to display a certain intial page. Set variable (on VMS, logical name) WWW_HOME to the full hypertext of the file or index you want to start with.
• Keyword search accepts longer strings.
• On VMS, VMS files may be accessed. The WWW address is still unix-like, with slashes, and is converted into VMS syntax by the browser. VMS users can now write their own hypertext and keep it on VMS, though it will only be readable (at the moment) from VMS machines.

June 91 version 0.9

• Bug fix in anonymous FTP. The first version with a-ftp access.

24 May 91 version 0.8

• Page size selection now works with -p (bug in version 0.7)
• Styles have been made more compact, plain text uses all 80 columns.
• Bug fix: Missing loop end condidtion caused crash when listing some documents
• Files with suffixes other than .HTML are treated as plain text.

21 May 91 version 0.7

• Parameters avaliable on the command line :-

-v

Shows trace comments, including the pathways taken to locate a file.

-n

Makes the program non interactive with the user. No prompts are shown, and after the node is displayed it exits the program

-p

Turns off the paging. The page size can be selected by adding the value immediately after the 'p'.

-a

Stops positions of anchors being shown in the text.

• These options are particulary useful when redirecting the input into either a file or to the printer. They can also be used in any order on the command line, as long as 'WWW' is the first arguement.
• When the recall command is used to view what files have been visited, the titles of the files are used, rather than the file name. If there is no title then the file name is used.

14 May 91

• The function HTOpen() called from HTAccess has been changed so that it takes two parameters instead of one. This extra one being a pointer to an address where the format style is stored as an integer. The translations of the integers to the formats can be seen in WWW.h. At the momment this extra parameter is not used but will be in the near future so that more files can be accessed.

10 May 91

• WWW now reads the formatted text into a double linked buffer one screen full at a time and then produces it on the screen. This enables checking of documents so that splitting of small paragraphs or titles does not occur at the bottom of the screen.
• An option is offered to return to the top of the present document being viewed.
• Tim added the necessary code so that WWW can now access remote files using anonymous FTP.

17 April 91

• Modified WWW so that it is also executable on the SUN machines., i.e. using ordinary C.
• First version realeased on PRIAM, for testing by a few users, to gain feedback.
• Accepts keywords with the execute command.

8 April 91

• Keywords can be entered on the command line.
• The input file is copied into a buffer as soon as it is opened, so that the input channel is closed as soon as possible and the server freed. The first 23 lines of the document are read into the buffer and produced onto the screen. As soon as this is done, the remaining file is read into the buffer so the input channel is closed.

7 March 91

• Created an array called 'string_space' which is filled with blank spaces to be used for printing out margins etc. This method of printing a string was found to be faster than individually printing spaces.
• A history mechanism has been included so that a list of all the documents viewed are stored so that the user can refer back to them using the BACK, HOME and RECALL commands.
• Changed code so that the browser can handle text which contains long words which exceed the allowed line length on their own. This is just done by continuing the word on the following line.
• Read titles and headings into a buffer before outputting so that in cases where the title has a word longer than the allowed line length can be dealt with (for example above).This could also be useful in helping to solve the above problem. Maybe extend the length of headings.

5 March 91

• Handles a "LISTING" tag by treating it in the same way as an "XMP" tag. This is because, in the case of the line mode browser, the screen is limited to 80 columns and so the browser is unable to work with the 132 columns which the "LISTING" tag normally expects.
• Handles an "ADDRESS" tag, which left justifies the text.

27 Feb 91

• Lists and the help menu are not so spread out, as before.
• The browser works with file numbers rather than the file pointers.
• Tidied up paging, with the last line of a page repeated at top of next.
• Deals with tags within anchors.

11 Feb 91

• HTTP access to cernvm server, including FIND and NEWS tested.
• Browser can be executed by 'WWW' , 'YP' (yellow pages), 'XNEWS', or 'FIND'.
• "PLAINTEXT" tag added. Prints out the node exactly as it finds it in the file.
• Prompt only contains appropriate options, as does the help message.
• Keyword search option added.

Before Feb 91

• Text formatting and line wrapping completed to a reasonable standard.
• Removed section of program where 'r' has to be entered in order to select a reference.
• When no hypertext references have been found, the browser informs the user, and doesn't offer the list option in the help menu.
• Produces an error message if the user tries to select a reference or menu, when no references have been found.
• Records whether an anchor is a NAME or an HREF.
• Stop **** END **** (now [End]) appearing in the wrong places. This problem appears due to the lines in the html file being too long, so this causes an error in the 'C' run time.
• Handles a glossary.
