Version 3.3.17, 2022-09-02

New feature: sort and uniq options added to the tabulation output control.

Version 3.3.16, 2022-07-22

Concordance Download now has an option to include the categories of a Categorised Query.

New system for handling compressed files implemented, and used to make the Export Corpus tool work better.

Version 3.3.15, 2022-05-04

Extended Corpus Installer plugins to make it possible for customised questions to be asked of the user.

Version 3.3.14, 2022-04-27

Fixed multiple bugs in the Lexical Growth Curve tool (among other bits and pieces).

Version 3.3.13, 2022-04-07

Added pagination buttons to extended context view.

Refined mechanism for right-to-left text display, so that it works properly to display aligned parallel data where one corpus is right-to-left and the other isn't.

Added buttons for sequential access to concordance extended context (“previous“ and “next“).

Added five new colour schemes (palettes chosen by Isolde van Dorst).

Fixed a bug in the HTML cache.

Fixed a bug that prevented people accessing corpora shared by their colleaguates.

Version 3.3.12, 2021-12-23

Added an HTML cache for improved performance.

Fixed many bugs in the plugin system for user’ own corpora, making it actually fit for general use for the first time.

Version 3.3.11, 2021-11-09

Enabled use of “data-” attributes on <span> tags in XML visualisations.

Version 3.3.10, 2021-10-14

Implemented the 'TAB Optimisation' in the CEQL Parser, which makes certain types of query run up to 10 x faster (see https://www.linguistik.phil.fau.de/2021/07/18/tab-optimisation-cqpweb/).

Fixed many, many bugs. These include: a bug in the display of the Query History for queries run in unsaved subcorpora; a bug in concordance download affecting download of metadata columns; a bug affecting the display of Corpus Installer plugins; a bug affecting AutoSave in categorised queries; and assorted others.

Version 3.3.9, 2021-02-10

Improved subcorpous and restriction management.

Version 3.3.8, 2021-02-06

Made the Restriction Cache Control render more quickly.

Fixed a whole lot of bugs arising from new features in the last two versions.

Version 3.3.7, 2020-07-13

Fixed a longstanding bug in extended context display alternative view where spaces in the alternative attribute caused words to disappear. As a result, the latest version of CWB (3.4.26) is now required.

New feature: it's now possible to request arbitrary annotations to be included within the concordance/extendedcontext.

New feature: it's now possible to create a subcorpus by direct upload of corpus position interval data.

Made it possible to download files from upload areas.

Improved the framework for running user-written CQPweb Apps for specialised tasks.

Implemented revised CEQL improvements (in both the built-in PHP module and the external Perl implementation). As a consequence, installations that use the Perl CEQL parser now require the most recent version of CWB-Perl.

Fixed bugs in user corpus setup; query merging; matrix creation; and elsewhere.

Did a whole lot of cleanup and reorganisation.

Added new function, run_query(), to the API. This is the core of the API, although many data access functions remain.

Version 3.3.6, 2020-04-24

Added two new query modification tools: expand and narrow.

Expand wraps around the CQP “expand to s-attribute” command for modifying queries.

Narrow changes a multiword result to a single token per hit (either the original leftmost position or the original rightmost position).

Categorised query concordances now autosave changes to categories (by default; can be turned off in user settings, or in the categorise-mode concordance).

Made distribution run faster in queries with many, many texts.

Fixed some major bugs in the wordcloud view of keywords (plus an assortment of minor bugs).

Version 3.3.5, 2020-04-15

New feature: users can now change the email address associated with their account.

New user setting: preferred keywords astatistic (Log Ratio by default).

Fixed bug in query-combination; also made fixed bugs in admin view of users' Query History.

Version 3.3.4, 2020-04-02

Bug fixes to internals (mostly table naming) and improvements to data structures for different kinds of saved data.

Some tweaks to the keywords interface.

Version 3.3.3, 2020-03-31

Improvements to the categorised query tools.

Bugfixes galore.

Version 3.3.2, 2020-03-27

Gave the collocation and distribution interfaces a bit of an overhaul.

Yet more bugfixes.

Version 3.3.1, 2020-03-15

Added a tool to the admin interface that checks for should-have-been deleted uncompressed CWB attribute files (deleting these can help save disk space).

Added pagination to feature matrix display.

Made it possible to build a feature matrix for texts in a particular subcorpous, rather than the whole corpus.

Added a new kind of template: catdesc (“category-description”) templates. These are sets of category handles with associated descriptions that can be applied to any classification-type metadata field.

Added a new keyboard shortcut to the query entry box: pressing ALT+Q now cycles through the query modes (ALT+SHIFT+Q does the same the other way).

Plus a big wave of crucial bugfixes for the 3.3.0 upgrade.

Version 3.3.0, 2020-03-12

Major upgrade: changed the database encoding to support full UTF-8 (including emoji characters) via MySQL/MariaDB's "utf8mb4" encoding, which was not available when CQPweb was initially invented.

Also, set up a system to use the best available collation (compatible with recent versions of MySQL and MariaDB) for all stored textual data.

Improved support for corpora in right-to-left scripts.

Removed unneeded backwards compatibility code. This means that CQPweb henceforth requires AT LEAST v7.3 of PHP, and AT LEAST v 3.4.21 of the CWB core.

Removed dependency on the tar and gzip programs (internal PHP functions used instead), although indexing corpora form .gz still relies on gzip (because cwb-encode uses pipes for this, rather than Zlib functions).

Made use of the awk, sort and head tools optional, ending the Unix dependency.

Added a "rendering cache" to simplify preservation of view-settings across different screens.

Added a subcorpus creation method that simply converts a saved query's matches to the intervals that make up the subcorpus.

Made it possible for annotations (p-attributes) to have their default case-sensitivity and accent-sensitivity set independently (this can also be set for annotation templates).

Annotations, and annotation templates, can now also specify on a per-annotation basis whether a frequency table should be built for that annotation (necessary for collocations and keywords, but actually a bad thing for some kinds of p-attribute data).

In consequence, the frequency-table management tools for corpora have been made rather more sophisticated.

Added many more functions to the external API.

Added a system for annotation templates to supply information for pre-indexed CWB corpora. Added a parallel system for XML templates!

Revamped the internal debug-message systemk for maximum utility and convenience.

Reworked the colour scheme system completely; added five new colour schemes using the new system.

Gave a few other aspects of the user interface a proverbial "lick of paint".

Added experimental query optimisation using CQP TAB queries to the CEQL parser.

Added plugin activation for query download plugins (and, eventually, others).

Added tool to view SQL daemon configuration within admin control panel.

Versions 3.2.42 and later versions of 3.2 contain only fixes for bugs, many back-ported from 3.3.

Version 3.2.41, 2020-01-09

Finalised the (so far undocumented) “run CQPweb apps” tool.

Improved memory usage in subcorpus manipulation.

Fixed a ton of bugs, including some major issues in distribution tables.

Version 3.2.39, 2019-07-04

Added a command-line script to install a corpus.

Version 3.2.38, 2019-06-12

Revamped corpus access permissions for keywords, to make matching up a greater range of datasets possible.

Made the new, internal CEQL parser into the default (so CWB-Perl is no longer necessary to run CQPweb).

Began integration work on the new Dispersion tool (code contributed by Andressa Gomide).

Fixed multiple bugs.

Version 3.2.37, 2019-06-07

Standardised the back-end data formats; also fixed some problems with one of the plugins.

Version 3.2.36, 2019-05-31

Added the "embed-page" tool as per feature request.

Added a tool for administrators to view users' upload areas.

Fixed multiple bugs.

Added the "lock password" tool for administrators to stop users changing their passwords.

Added a button for administrators to reset all of a user's preferences to default values.

Fixed multiple bugs.

Version 3.2.34, 2019-05-07

Added the "colleaguation" networking system for data sharing (experimental only).

Version 3.2.33, 2019-04-24

Many, many bugfixes from the previous release.

Updated the required version of PHP from 5.x to 7.0 (the latter itself being out of date but still present in Debian).

Made improvements to the CQP class making it easier to set system options, change registry, change data directory, etc.

Version 3.2.32, 2019-04-15

Added a long-requested major new feature: users can now install their own corpora.

Added wordcloud-view to the keywords tool.

Added new built-in corpus statistic: 1,000 token Standardised TTR.

Added a new collocation statistic: conservative estimate of Log Ratio (credit: Stefan Evert). Also added this statistic to the keywords tool.

Changed the default collocation statistic and the default keywords statistic to Log Ratio.

Added tool to manipulate Saved Queries by merging two existing queries into one.

Added a built-in CEQL parser, allowing the dependency on Perl to be ended.

Added additional, more complex methods for defining variables for multivariate analysis.

Added programmatic access to CQPweb via an API (which has, so far, only a few unexciting functions; but more is on the way!)

Added better tools for measuring disk usage for database tables, as well as a UI to optimise tables that are wasting a lot of disk space.

Added an internal replacement for the now-very-old wztooltip.js library for rendering tips.

Changed the required version of the CWB core to 3.4.10 or later.

Fixed an edge-case bug related to the collation of handles in various table fields.

Ended support for Internet Explorer; the browsers for which bugs will be accepted are henceforth Edge, Chrom[e,ium], Safari, and Firefox.

Version 3.2.31, 2017-10-04

Completed the feature that adds new data to a corpus without re-indexing it (this can now be done for p-attributes as well as s-attributes and corpus metadata).

Version 3.2.30, 2017-10-04

Added an alternative method to insert new p/s-attributes: via rescanning the corpus registry file.

Version 3.2.29, 2017-09-29

Added a new method of corpus export: separate text files within a zip archive.

Version 3.2.28, 2017-09-28

Added a way to add new data to a corpus without re-indexing it (s-attributes and corpus metadata).

Version 3.2.27, 2017-09-25

Revamped the Distribution system to allow for non-text-based Distrbution statistics.

Fixed a longstanding and embarrassing potential security hole (non-use of CQP QueryLock for user queries).

Added Lexical Growth graph-drawing function as first of an anticipated series of data visualisation tools.

Added a system for XML visualisation templates.

Added an option for users to get frequency-list downloads in AntConc-compatible format.

Added a control to the search form allowing the CQP match-strategy to be set.

Tweaked some database structures in an attempt to optimise.

Fixed a CEQL bug with queries of the form {LEMMA/TAG}: the fallback to searching secondary plus tertiary annotations was not working, now it is.

Fixed multiple other bugs, including a potential data-shadow in the Restriction cache.

Version 3.2.26, 2016-12-23

Added access to CQP binary files for privileged users (for archiving, etc. purposes).

Added administrative tools for creating and editing user privileges.

Added additional admin tools for controlling user login sessions, as well as some extra security measures to the change-password mechanism.

Version 3.2.25, 2016-12-15

Added a new feature (yay!): experimental lexical growth curve analysis system.

Fixed a bug that stopped XML values containing spaces rendering correctly in the concordance.

Fixed a number of bugs in the storage of subcorpora containing very many texts selected individually or using the scan text metadata tool.

Added a tool in the administrator's interface to delete the entire query history (thus, setting the usage statistics back to empty values).

Reorganised the text metadata management screen.

Improved error messages in the save-query system.

Improved the gizmos for monitoring disk usage: query cache control now distinguishes user-saved data from deletable cache data, user profile view says how much disk space they are using for saved/categorised queries.

(v 3.2.24 was a partial way-point towards 3.2.25, it gets no separate entry.)

Version 3.2.23, 2016-08-08

Made parallel-corpus view work properly in categorise-query mode.

Made the limit on the size of file a user can upload configurable via the privilege system.

Fixed one or two bugs.

Version 3.2.22, 2016-07-31

Version 3.2.21, 2016-07-04

Fixed a critical bug in the code calculating confidence intervals for keywords and lockwords.

Version 3.2.19, 2016-06-29

Added the ability to create subcorpora from sub-text regions containing a query hit.

Added metadata view for XML-based ID-link metadata (e.g. speaker metadata in spoken corpora).

Version 3.2.18, 2016-06-25

Reimplemented the XML visualisation system.

Made breaking paragraphs after punctuation in extended context view optional, rather than always implemented.

Allowed "extra code files" (JS/CSS) to be added to enhance the visualisations.

Version 3.2.17, 2016-06-03

Fixed a bug affecting the installation of pre-indexed corpora.

Multiple bug fixes for the previously-added subcorpus/restricted query features.

Version 3.2.8, 2016-02-19

More big internal reorganisation.

Added query restriction by conditions on corpus XML.

Added, likewise, subcorpus creation by conditions on corpus XML.

(v 3.2.7 was a partial way-point towards 3.2.8, it gets no separate entry.)

Version 3.2.6, 2016-02-06

More effort to rework the internals for XML support.

By popular demand: added back the "create batch of accounts" tool in the admin interface.

Added "alternative view" to extended context, allowing historical corpora to show original spelling.

Improved the interface for managing user accounts a bit.

Version 3.2.5, 2016-01-23

Fixed numerous minor bugs.

Made the tabulation-download system able to access s-attributes.

Reworked some of the internals as a stepping stone to (yet more) XML support.

Version 3.2.4, 2015-11-19

Finished (for now) the XML metadata management functions.

Added plain-text download of feature matrices.

Added monochrome view to assist visually-impaired accessibility.

Rewrote the Distribution function for full BNCweb-style functionality (plus a fix to the broken sort buttons).

Fixed a potential security bug in the signup and persistent-login systems.

Fixed multiple minor bugs from the big 3.2 upgrade.

Fixed a bug affecting thinned queries, and another affecting collocate highlighting in concordances.

Version 3.2.3, 2015-10-15

Metadata templates now work properly.

Added list of CWB attributes to query forms (displays when "CQP syntax" is selected).

Fixed more bugs.

Version 3.2.2, 2015-10-09

Fixed a cluster of bugs, including some critical, in the corpus setup process.

Added metadata templates (some functionality incomplete).

And finally: added two new colour schemes just for the hell of it (there's more to life than databases, tha knows).

Reorganised the "manage metadata" functions.

Added management functions (not yet entirely complete!) for XML metadata.

Added potted explanations of collocation statistics to the collocation screen.

Reorganised the keyword output screen to give a richer analysis.

Added experimental effect-size statistics for keyness: Log Ratio unfiltered, and Log Ratio with LL or CI Filter.

Added tool to extract lockwords using Log Ratio.

Added the same Log Ratio with LL filter to the Collocations tool.

Fixed a bug affecting collocation/sorting done on uploaded queries.

Version 3.1.6, 2014-04-11

Version 3.1.1, 2014-01-20

Fixes for the inevitable bugs following a large update.

Version 3.1.0, 2014-01-20

Revamped user account system.

Added a script to automatically upgrade an existing CQPweb MySQL database to match a more recent version of the code.

Added a script to import user groups from the old system.

Added a script to import group privileges from the old system.

Rewrote configuration file format and added documentation to system administrator's manual.

Many other miscellaneous tweaks, improvements and architectural changes.

Version 3.0.16, 2013-12-24

Fixed two minor bugs in the concordance download function.

Version 3.0.15, 2013-11-20

Improved background handling of frequency lists (no changes a user would notice).

Version 3.0.14, 2013-11-18

Added protection against users compiling very, very large frequency tables for subcorpora or on-the-fly for collocations.

Version 3.0.13, 2013-11-04

Added some extra protection against possible XSS (cross-site-scripting) attacks.

Version 3.0.9, 2013-04-06

More bug fixes.

Added a new feature: a full file-by-file distribution table can now be downloaded.

Adjusted the Distribution interface to make it more like the Collocations interface.

Version 3.0.5, 2012-02-19

Just bug fixes, but major ones!

Version 3.0.4, 2012-02-10

New feature: optional position labels in concordance (just like "sentence numbers" in BNCweb) (this feature originally planned for 3.0.3 but not complete in that release).

Extended the XML visualisation system to allow conditional visualisations (ditto).

XML visualisations now actually appear in the concordance (but only paritally rendered: they look like raw XML).

Version 3.0.3, 2012-02-05

Mostly a boring bug-fix release, with only one new feature: users can now customise their default thin-mode setting.

Fixed a bug in concordance download function that was scrambling links to context.

Fixed a bug in categorisation system that allowed invalid category names to be created.

Fixed a bug in frequency list creation that introduced forms in the wrong character set into the database.

Fixed a bug in the keyword function's frequency table lookup process.

Version 3.0.2, 2011-08-28

Added the long-awaited "upload user's own query" function.

Finished the administrator's management of XML visualisations. Coming next, implementation in concordance view.

Made it possible for a user to have the same saved-query name in two different corpora.

Fixed a bug that made non-reproducible random thinning, actually always reproducible!

Version 3.0.1, 2011-08-20

Implemented a better system for sorting corpora into categories on the homepage.

Fixed a fairly nasty bug that was blocking corpus indexing.

Fixed an uninformative error message when textual restrictions are selected that no texts actually match (zero-sized section of the corpus). The new error message explains the issue more clearly.

Version 3.0.0, 2011-07-18

New feature: custom postprocess plugins!

Fixed some bugs in unused parts of the CQP interface.

Added support for all ISO-8859 character sets.

Version number bumped to 3.0.0 to match new CWB versioning rules, though CQPweb is in fact now compatible with the post-Unicode versions of CWB (3.2.0+).

Version 2.17, 2011-05-18

Fixed a fairly critical (and very silly) bug that was blocking compression of indexed corpora.

Added extra significance-threshold options for keywords analysis.

Version 2.16, 2011-03-08

Added a workaround for a problem that arises with some MySQL security setups.

Added an optional RSS feed of system messages, and made links in system messages display correctly both within webpages and in the RSS feed.

Created a storage location for executable command-line scripts that perform offline administration tasks (in a stroke of unparalleled originality, I call it "bin").

Added customisable headers and logos to the homepage (a default CWB logo is supplied).

Fixed a bug in right-to-left corpora (Arabic etc.) where collocations were referred to as being "to the right" or "to the left" of the node even though this was wrong by about 180 degrees.

Version 2.15, 2010-12-02

Licence switched from GPLv3+ to GPLv2+ to match the rest of CWB. Some source files remain to be updated!

A framework for "plugins" (semi-freestanding programlets) has been added. Three types of plugins are envisaged: transliterator plugins, annotator plugins, and format-checker plugins. Some "default" plugins will be supplied later.

Some tweaks have been made to the concordance download options, in particular, giving a new default download style (“field-data-style”).

For the adminstrator, there is a new group-access-cloning function.

The required version of CWB has been dropped back down to a late v2, but you still need 3.2.x if you want UTF-8 regular expression matching to work properly in all languages.

Improvements to query cache management internals.

Plus the usual bug fixes, including some that deal with security issues, and further work on the R interface.

Version 2.14, 2010-08-27

Quite a few new features this time. First, finer control over concordance display has been added; if you have the data, you can how have concordance results rendered as three-line-examples (field data or typology style with interlinear glosses).

The R interface is ready for use with this version, although it is not actually used anywhere yet, and additional interface methods will be added as the need for them becomes evident. It goes without saying that you need R installed in order to do anything with this.

The new Web API has been established, and the first two functions "query" and "concordance" created. Documentation for the Web API is still on the to-do list, and it's not quite ready for use...

Plus, a new function for creating snapshots of the system (useful for making backups); a "diagnostic" interface for checking out common problems in setting up CQP (incomplete as yet); and some improvements to the documentation for system administrators.

Also added a new subcorpus creation function which makes one subcorpus for every text in the corpus.

Version 2.13, 2010-05-31

Increased required version of CWB to 3.2.0 (which has Unicode regular expression matching). This means that regular expression wildcards will work properly with non-Latin alphabets.

Also added a function to create an "inverted" subcorpus (one that contains all the texts in the corpus except those in a specified existing subcorpus).

Plus, as ever, more bug fixes and usability tweaks.

Version 2.12, 2010-03-19

Added first version of XML visualisation.

Also made distribution tables sortable on frequency or category handle (latter remains the default).

Also added support for CQP macros and for configurable context width in concordances (including xml-based context width as well as word-based context width).

Plus many bug fixes and minor tweaks.
